Industrial Parts Cleaning… Buying vs Hiring vs Outsourcing, Which Is Best?

Industrial Parts Cleaning… Buying vs Hiring vs Outsourcing, Which Is Best?

Industrial parts cleaning is essential for keeping your machinery and equipment in the best possible condition. Using the latest cleaning techniques, you can eliminate excess spending and reduce your downtime, helping your business to run smoothly. When it comes to industrial parts cleaning there are various options to choose from. You can purchase your own industrial cleaning tools, hire the equipment you need to do the job yourself, or outsource the task to a specialist. In this article, we are weighing up the pros and cons of each option, to help you decide if buying, hiring, or outsourcing is the best option for your industrial parts cleaning.

Buying Industrial Cleaning Equipment

Many organisations choose to invest in their own equipment for industrial parts cleaning and keep the entire service in house. 


  • You own the equipment 
  • You have total control over use of the equipment
  • Always available and always on site for industrial parts cleaning whenever you need it
  • You set and maintain the standards yourself


  • Capital cost
  • Maintenance of parts often requires specialist labour
  • Need to buy consumables
  • Waste disposal must be handled in house
  • Additional operation with a different approach to processing/manufacturing 


What is the upfront cost? 
Typically a basic ultrasonic machine will cost from £5k to £25k, and a basic rotary jet wash from £10k to £20k.

What are the ongoing costs of operating these?
Running costs for power and chemicals will go from £100 to £1000 per month dependent upon size and usage.

Ultimately the cost of buying industrial part cleaning equipment will depend on:

  • The size of the machine required
  • Its complexity, because the more the machine is modified to the specific requirements of cleaning the parts, e.g. spray wash, filtration, oil separation, the more it will cost
  • Multi process cleaning operations, e.g. wash, rinse, dry
  • Automated handling to load, move and unload the parts during cleaning without manual handling
  • Variable operations to accommodate different parts, or different cleaning criteria

FAQs For Buying Industrial Cleaning Equipment:

Who are the most well-known manufacturers/suppliers?
There are more manufacturers of machinery than companies offering industrial cleaning services. Ultrasonic machine manufacturers include:

  • Allendale
  • Alphasonics
  • Camsonic
  • Caresonic
  • EJ Electronic
  • Hilsonic
  • Mecwash
  • Technowash
  • Turbex
  • Ultrawave

The most suitable manufacturer for you will depend upon your specific requirements and budget. Many manufacturers have particular expertise in an industry so would be better for businesses operating in their area of expertise.

Jet wash machine manufacturers include:

  • Bio-Circle
  • Rotajet
  • Safetykleen
  • Turbex
  • Vixen

Similarly to ultrasonic equipment manufacturers which one is best will depend on your specific requirements as again many manufacturers have a specialist expertise in specific industries.

Should you get a solvent or aqueous based one?
The trend is more to the use of aqueous cleaners rather than solvents since these are environmentally and safety wise seen as far better than their solvent equivalents. There are also many legal restrictions on the uses of certain solvents. 

However, the vast majority of aqueous solutions contain some solvents, and there are a wide variety of closed system solvent cleaners that both recondense the solvent cleaner and have very low solvent emissions. 

Open tank solvent cleaning systems are largely consigned to history. However, as a consequence of their more complex nature, solvent cleaning machines do tend to be significantly more expensive than aqueous based cleaners.

What kind of customer is this a good fit for?
Buying equipment is usually the first option considered and is often the best option where all or many of the following factors are in play;

  • Cleaning is ongoing and an intermediary process between other operations.
  • Required turnaround times on cleaning are immediate and ongoing. 
  • Production is continuous rather than batch production.
  • Parts being cleaned are relatively homogenous and straightforward to clean.
  • The cleaning process is a single operation rather than multiple processes using different technologies.
  • Cleaning will be a continuing requirement, and not a temporary one.
  • The logistics of moving parts off site for cleaning are complex, costly or compromise security. 

Hiring Industrial Cleaning Equipment

If buying isn’t the right choice, you might consider hiring equipment for industrial parts cleaning.


  • No upfront capital cost
  • The hire company should assist in the selection of the right equipment for the job
  • The hire company will usually supply a replacement machine in the event the hired one stops working
  • The hire company usually provide support in terms of training staff in the machine’s operation, and the chemistry and waste disposal
  • Costs are fixed and known for the length of the contract
  • The cleaning operation is still fully under the control of the Company itself


  • Lengthy contracts with expensive termination clauses
  • The Company will need to provide their own personnel and factory space to operate and house the equipment to do the cleaning 
  • Services and disposal considerations are still ultimately the responsibility of the Company
  • Maintaining the required cleanliness standards are still the Company’s responsibility.
  • Variations in quantities, part type, etc.. can mean the original machinery and cleaning process is no longer appropriate or adequate. The hire company may not always be accommodating or responsive to these changes


Costs of equipment hire vary tremendously and can take different forms depending upon the hire arrangement of just the machinery, or the more usual machinery, chemical, maintenance and waste disposal. However, costs typically range from £500 to £1,000 per month.

What are the ongoing costs of operating these? 
Again, extremely variable depending on the arrangement. Most contracts do ensure costs remain fairly constant throughout the period, but changes in equipment and frequency of the periodic maintenance/chemical changes will alter the rates.

What can drive the cost up from the “starting from” price? 
The biggest single factor is increasing the frequency of maintenance visits. In fact visits from the hiring Company are probably the biggest single influence on the hire cost after the size of the machine under hire.

FAQs For Hiring Industrial Parts Cleaning Equipment

Where can I hire industrial parts cleaning equipment from? 
Safetykleen are the biggest single hirer of cleaning equipment, but other companies like bio-circle and rotajet are also active in this market as well as straight selling of the equipment.

What should I consider when hiring?
As with any hire contract the devil is in the detail. Particular attention should be paid to:

  • Frequency of machine maintenance, including replenishment of chemical and disposal of waste, and the costs of increasing and decreasing this frequency.
  • What happens should the machine break down in terms of response rates and replacement.
  • The required notice period and penalties for termination of the contract.

Outsourcing Industrial Cleaning Equipment

Another common option for industrial parts cleaning is outsourcing the job to a specialist firm.


  • Outsourced companies like Sonic Solutions offer a range of solutions not just one
  • No financial outlay on machinery
  • More cleaning solutions available
  • No upfront capital cost
  • No setting up of an in-house cleaning operation requiring trained staff 
  • No services requirements for water/electric/ventilation/waste disposal/chemical storage & handling etc..
  • No ongoing maintenance costs of equipment
  • No ongoing consumables costs for power and chemicals
  • No lengthy learning curve for getting the right level of cleanliness
  • Focus remains on own area of expertise, making the product, not cleaning the product


  • Logistics of packing and transporting the items to be cleaned, both direct costs and time delay
  • Potential exposure to failures of the third party doing the cleaning
  • Increased risk of damage or loss to items being cleaned while off site
  • Security risk of sensitive items whilst off site
  • Lack of knowledge of item being cleaned by those cleaning it compared to those who make or use it


What is the cost to outsource industrial parts cleaning?
Cleaning costs vary enormously depending upon the complexity of the clean (particularly multi-process), size/weight and quantities being cleaned, the speed of turnaround required and the frequency of cleaning.

Typically, small simple cleans cost from £50 to £100, whilst more complex cleans will be £1000 upwards. Frequency and volume reduce unit charges but increases total cost.

What can drive the cost up from the “starting from” price? 
Higher levels of contamination, complexity of the item being cleaned, one-off cleans, multi stage (pre-treat, wash, rinse, dry, packaging etc..) and multi cleaning processes (pyrolysis, jet wash, media blast, ultrasonic etc..) can all increase from the base price

FAQs For Outsourcing Industrial Parts Cleaning

Why choose outsourcing over buying or hiring?
The most frequent reason for cleaning being outsourced is that in-house cleaning is unpopular with staff and consequently done very badly. This can frequently result in higher costs attributable to poor quality than the extra cost of subcontracting out the cleaning to an expert who does it properly, first time.

Why does the cost of outsourcing seem high?
The costs of industrial parts cleaning is frequently underestimated by people who do not understand the full process of cleaning and view it as “only cleaning”. Where multi process cleaning is required to get the desired level of cleanliness, in-house operations frequently miss steps out with the consequence being that cleanliness specifications are not met.

Is Buying, Hiring, Or Outsourcing The Right Option For My Business?

There is no one size fits all approach to industrial parts cleaning. Every business is different and unique requirements mean that each option needs to be carefully considered. Here we have broken down the three options and the scenarios when they might be most suitable:

Buying equipment for industrial parts cleaning might be the most suitable option if:

  • The requirement is long term and relatively stable
  • The cleaning process is well known 
  • The cleaning process is relatively straightforward
  • Items to be cleaned are fairly homogeneous
  • The equipment required is affordable to the business (either low cost, or a financially affluent business)
  • Cleaning is an intermediate and integral part of a process, which is difficult or impossible to interrupt. Cleaning must therefore be in-house with own machines under the complete control of the business
  • Intellectual property dictates complete confidentiality of all parts of the production process

Hiring equipment might work for you company if:

  • The equipment required is not affordable to the business
  • Items to be cleaned are varied so a wide range of equipment is required.
  • The cleaning requirement is well known, BUT the volumes and duration of requirement are potentially variable so equipment requirements may have to be revised

Outsourcing industrial parts cleaning could be the perfect solution if:

  • Your company has little or no cleaning experience or expertise
  • The cleaning methods and requirements are not well known by your team
  • In-house cleaning has proven ineffective and costly
  • There is no scope for setting up an in-house cleaning operation (space, services, environmental issues etc..)
  • The cleaning requirement is of a specialist nature (often multi staged and multi processed)
  • The cleaning requirement is for a limited period of time (not warranting the expense of setting up cleaning operations)
  • The cleaning requirement is critical, vital and immediate and there is insufficient time or resources to set up an in-house cleaning operation (the cleaning contract is a prelude to setting up an in-house cleaning operation)
  • Cleaning is incompatible with existing operations, be it the noise, chemicals, waste disposal, or other environmental considerations
  • Cleaning requirements are very variable and in-house cleaning capacity may be overloaded so subcontract cleaning handles the occasional excess load.

Erema Maintenance – 5 Tips to Keep Your Hot Melt Filter Disks in Better Shape & Lasting Longer

Erema Maintenance – 5 Tips to Keep Your Hot Melt Filter Disks in Better Shape & Lasting Longer

Erema are probably the most popular brand in the UK of machinery to make pellets from recycled plastics. Their system of continuous hot melt filtration allows for high productivity of an extremely pure product.

The laser cut discs through which recycled product is melted and passed through prior to pelletisation are key to the entire process. If they get blocked (or blinded) then pressure builds up and throughput drops. Worse, if the pressure causes the disc to burst then impurities enter the finished product. Proper maintenance of these discs is therefore critical. In addition to production issues from blinded or burst discs the cost of replacements is eye watering, so proper maintenance of Erema filter discs is a problem facing all managers of Erema extrusion lines. Yet the traditional cleaning method of burn-off of residual plastic only partially clears the filter. Here at Sonic Solutions we specialise in the cleaning of Erema laser filter screens. We have worked with some of the UK’s leading plastics recyclers over the last 3 years and developed a cleaning process that has seen replacement costs cut in half, throughput increased by over 10% and downtime significantly reduced for nearly all our customers. We are the first to acknowledge the contribution of our customers in the development of this process. We have also learnt the following top tips from our Erema using customers in the maintenance of these discs to reduce wear and tear and keep them running better and longer. We thought it might be helpful to managers of Erema hot melt extrusion lines to share these tips on how to maintain and clean their filter discs.

1: Scheduled Downtime

If you wait for your machine pressures to skyrocket between laser filter screen changes then you risk the screen bursting requiring costly replacement as well as impurities entering your finished product. Changing the screens at frequent and specific predetermined times brings many benefits, including a longer life for your screen and a reduction in unplanned downtime, one of the costliest, most stressful and embarrassing occurrences in any production line. The cost of more frequent cleaning is a fraction of the cost of unplanned and frequent downtime and resultant replacement costs.

2: Blade Change

Metal particulate can get trapped in the screen and dragged around and around the filter by a blade too blunt to cut through it, causing the deep scoring damage. Yet blades are inexpensive compared to the replacement cost of a screen. A regular customer of ours changes their blades every week in a scheduled downtime (they also change and clean their screens at this point). They report that some screens have lasted 8-9 cycles of burn off/ultrasonics as a consequence of this weekly changing of blades alone.

3: Screen Explosion

When re-using damaged or scored screen you should reduce the operating pressures and monitor carefully. You shouldn’t have to clean your filter core regularly since the material entering it should not be contaminated but on occasions when the screens burst, contaminated material will enter and block the core. It is then good practice to burn off and clean your core and pelletizing head as large pieces of wood or metal can enter the wedge in the holes, reducing throughput and cause another blockage. Usually a straightforward burn-off and jet wash will be adequate since there are no small holes to clean.

4: Burn off temperatures and times

For the best results when burning off your laser screens we have found that a temperature between 400-450 degrees centigrade works best. The oven should be slowly raised to this temperature and held there for around 3-4 hours. The oven should then be allowed to cool down gradually and not opened until the temperature falls below 250 Centigrade. This prevents flare-ups of any remaining plastics and rapid cooling of metal with the  potential for warping and distortion. Larger items like the core, screens and blades with higher quantities of waste material to burn off may require longer to completely degrade the waste plastic. It is also important to allow sufficient space between items whilst in the oven so the heat can circulate properly and allow the molten plastic to melt away from the parts. Failure to do so can lead to an incomplete burn-off of the plastic contaminant on the items in the middle.

5: Ultrasonic cleaning and surface passivation

Traditional cleaning methodology for the filter discs tends to stop at a quick jet wash after burn off. Whilst this is fine for the heavy items like the core, blades, pelletising head and screws, the laser screens with their ultra fine mesh require a more complex multi-process clean. After burn-off and jet wash they still contain trapped, burnt carbonised plastic in the fine mesh and, if not dried properly, also rust heavily again blinding the micron sized holes. Ultrasonic cleaning in acid solution for around 3 hours cleans the screens to a near 100% cleanliness level. Furthermore, after the acid clean surface passivation in an rust inhibiting alkaline solution followed by a thorough drying ensures they remain clean and rust free until use. It is a classic case of the whole being greater than the sum of the parts. The whole process we employ to clean filter discs does take longer and cost more than the traditional method, but the benefits make the extra effort and cost well worth it. Laser filter screen lifetimes can be extended to double or triple compared to burning alone. Throughput can be increased by up to 20% because of reduced blinding. Extended times between blockages reduces downtime and bursts significantly. We know that the material type and quality going in has a lot to do with what goes on in the extruder, but a lot of that is out of your control. Maintenance of your hot melt filter line is something you can control. We hope the above tips are helpful.

How to Perform a Foil Test in an Ultrasonic Cleaning Bath

How to Perform a Foil Test in an Ultrasonic Cleaning Bath

When a customer asks us how they can check the performance of their ultrasonic tank, the easiest way to do it is through a foil test.

It is really easy to do and all you need is a piece of aluminium kitchen foil and your ultrasonic tank!

Firstly you want to fill your tank with clean mains water with no chemical in. A lot of ultrasonic chemicals will react with aluminium, especially thin foil.

Next you want to take a small square of aluminium foil, 10㎠ should do it.

Then, using gloves, you need to hold the foil under the solution for 30 seconds. While doing this, try to keep the foil straight and avoid it curling in on itself as this will not give the required results.

Next you want to hold the foil up to a light and see the results.

Good result

If the ultrasonic bath is working effectively then what you should see is an even covering of pinprick holes throughout the foil. The holes should be relatively uniform in size and be evenly distributed.

Bad result

If the ultrasonics are not working correctly you may see little or no holes on the foil. This would indicate that some or all of the transducers are no longer working.

Patchy holes

Another result you may see is large holes on some parts of the foil and little to no holes on other parts. This is caused by there being an ineffective or missing sweep frequency. This results in “Hotspots” of ultrasonic activity which can seriously damage your parts if not fixed.


For the best results, repeat this test in different parts of the tank to make sure there is consistency throughout. The larger the tank, the more tests should be carried out.

When Does it Make Sense to Clean Your Own Parts?

When Does it Make Sense to Clean Your Own Parts?

If you are undertaking a new project that requires parts to be ultrasonically cleaned, a question you may ask is:

Should we undertake the cleaning ourselves or outsource it?

To decide which option is better for your business, there are several points that you should consider.

What volumes are you expecting to clean?

If you are only expecting a small volume of parts to need cleaning then it would be easier to outsource the cleaning work. Even a small industrial ultrasonic tank will cost upwards of £2000. If you only have 500 items that a cleaning company such as ourselves can clean for £1 per item, it makes much more financial sense to outsource.

Is the project ongoing?

This ties in with the volumes. Are you going to be producing a certain volume of parts per month indefinitely? Or is it just a few parts whenever they are ordered? 

If you have a full production schedule where you know you will require ultrasonic cleaning for a given length of time, then it is a good idea to look into purchasing your own equipment.

How much budget do you have?

As I  have already said, ultrasonic baths can be very expensive, especially if you are looking to clean large items. If you are working on a multi-million pound project then cost may not be an issue. But for most, a £50,000 investment in machinery cannot be taken lightly. Before you even consider purchasing your own ultrasonic bath, you should take a detailed look at your budget and see how much capital you have to work with. And yes, you can pick up a cheap 5 litre tank from amazon, but they are not designed for industrial use and will not be able to handle volume work.

Have you considered the additional costs?

As well as the initial expense of the tank, there are also the running costs that have to be considered.

Cleaning solution – The chemical that is added to the tank.

Power – The energy required to use the tank.

Waste disposal – The correct disposal of your waste solution.

Do you have the right personnel?

Are you going to have a dedicated member of staff to operate the tank or are your existing production staff going to take on the roll? Whatever you decide, you must ensure that whoever is operating the machine has adequate training to get the best results from it.

Other things to consider are the amenities needed for your own tank.

Do you have enough free floor space?

Do you have a water and power supply?

Is there adequate ventilation?

Have you considered health and safety factors?

When operating an ultrasonic tank, PPE must be worn to protect the operator from accidents. This is usually gloves, goggles, and an overall but some chemicals require a mask to be worn too. Wherever an ultrasonic tank is situated on a company’s premises they need to have a dedicated area where PPE must be worn beyond a certain point.

Do you just need it for one job?

If you are only producing one part that needs to be ultrasonically cleaned out of a large product range then you have to consider whether the machine is going to be used enough to warrant buying one.  That said, once you have your own tank, it’s easy to find things that could do with an ultrasonic spruce up.

So when DOES it make sense to get your own machine?

We get a lot of enquiries from people looking into getting their own tank and around 80% of them are put off once they hear the cost of the tank they require. Unless you are cleaning volumes of parts on a regular basis, then it is best to leave it to the professionals and use an outsourced company like ourselves. 

If your production is time-sensitive and you want to stay in control of the entire process then it makes sense to keep the cleaning in house. The logistics of sending out parts to a third party can add days to a production schedule and for some this is just not viable.

How Clean Will it Be?

How Clean Will it Be?

When we receive an enquiry for cleaning parts, a question we get asked a lot is “How clean will it be when we get it back?”

The simple answer to this is: “How clean does it need to be?”

With ultrasonic cleaning, there is cleaning action right down to the molecular level, meaning even the tiniest particles can be removed from an item. How clean the item needs to be is dictated by the next process the item will go into. For example, We have cleaned sensors that will go into oilfields for one of our customers. For the next process, the sensors need to be completely free of hydrocarbons or they may cause an explosion in the oil well. We therefore devised a multi-stage cleaning process which we know will leave the items completely free of these hydrocarbons.

A multi-stage cleaning process is the best way to ensure an item is as clean as it needs to be for the next process. If an item doesn’t need to be clean to the molecular level, then a two-stage process will usually suffice. This is usually an ultrasonic wash followed by a mains water rinse. For deeper cleaning, we usually add a demineralised water ultrasonic rinse at the end. If the cleaning specification runs even deeper than that, we can add different stages of ultrasonic cleaning to the process. This could be another clean in the same chemical but in a different, clean bath. Sometimes we may use a different chemical if there is more than one contaminant.

Ultrasonic Cleaning vs Jet Washing for Precision Engineers

Ultrasonic Cleaning vs Jet Washing for Precision Engineers

Jet blast cleaning is the process of using a high-pressure water pump to generate a flow of pressurised solution (up to 40,000psi) which is passed through a small diameter orifice to form a coherent stream of pressurised fluid. This jet of solution is then directly applied to any objects to be cleaned. The solution is usually water based, often containing a chemical to assist in removing the contaminant, and may also be heated to further assist the cleaning process.

Ultrasonic Cleaning uses the varying pressures created by high frequency sound (greater than 20Khz) as it passes through solution to create and then implode tiny vacuum bubbles (1-200 microns). The force exerted by these implosions (up to 20,000 psi) are intense over a small area, removing particulate adhering to any item submerged in the solution.

What can it clean?

It can be used to clean a wide variety of items relatively quickly and easily. Generally, it can be used to clean any accessible surface that can withstand the high-water pressures. Traditionally used for cleaning volumes of items with straightforward surface geometry and loose oil and particulate, it is used widely in precision engineering for the removal of cutting oils and swarf after machining.

Pros of ultrasonics over jet wash

  1. By its nature ultrasonics cleans all surfaces which the solution touches, offering a universal clean to any item, irrespective of its surface geometry. In contrast jet washing only cleans the surface under the jet so internal chambers, and inaccessible surfaces, or surfaces with uneven geometry, are impossible to clean to a very high standard with this method. This shortcoming has been addressed by the use of sensor robotics within the cleaning process to hold the item and move it and the jet nozzle to expose all surfaces to the jet stream. Companies such as MecWash have developed some extremely sophisticated machines to overcome this shortcoming. The price of this complexity in both financial and time aspects is considerable however.
  2. Ultrasonics uses a fixed amount of water in the cleaning bath which can be recycled and filtered to last a considerable period. Jet washing uses large volumes of water which can become waste (up to 1500 Litres per minute), although most modern jet wash units filter and recycle the waste solution to a certain extent.
  3. High pressures used by jet wash systems can damage delicate and light objects which move about when hit by high-pressure jets. In contrast, the forces created by ultrasonics suck dirt away from the item so do not move it around with the consequent potential for damage.
  4. Ultrasonics can achieve extremely high levels of cleanliness since they function at the micron level. The microscopic bubbles created in the liquid medium grow to a maximum size proportional to the ultrasonic frequency. At 20 kHz the bubble size is roughly 150 microns in diameter, reducing to 100 microns at 30 kHz and 38 microns at 80 kHz.
  5. Ultrasonics removes dirt from the surface into the solution, rather than just blasting from the surface. Where dirt eventually lands in a jet wash process is uncertain, and some residue is merely moved from one part of the surface onto another.
  6. Ultrasonic cleaning is more flexible and adaptable being able to use different solutions to remove a wide variety of contaminants ranging from oils to scale and rust. By contrast jet washing is almost invariably used to remove oils, loose particulate, inks and paints. It is not generally successful in removing scales and rusts where an acid-based solution can be used with ultrasonics.

Pros of jet wash over ultrasonics

  1. Jet washing can remove large volumes of tough grime, both wet and dried. With a recirculating and filtered system, large quantities of dirt can be effectively removed from items. Ultrasonic solutions can be filtered and recycled but large volumes of dirt put into the solution will diminish the effectiveness and efficiency
  2. Jet washing can be used safely in potentially volatile environments/situations, since it is invariably within a contained unit.
  3. Jet washing is fast and economic to clean large volumes of parts. Where the objective is to make parts safe to handle for the next process by removing the majority of oils and swarf rather than cleaning to a reliable high standard, jet washing is more economic than ultrasonics.


Ultrasonic Cleaning is probably the preferred cleaning methodology where parts to be cleaned have the following characteristics;

  • Uneven surface geometry with internal chambers and small apertures;
  • A high level of cleanliness is required. Where parts undergo further processes, or are a component of a part being used in a very demanding application, then the level of cleanliness required is likely to be higher than jet washing can achieve.
  • Small numbers of variable parts are required, so ultrasonic immersion works far better than jet washing.
  • Where the contaminant to be removed is more than a simple particulate and oil.
  • The volume of dirt to be removed is relatively low, so the cleaning solution does not become too contaminated, too quickly. A pre-wash and filtration can overcome this but adds cost and complexity.
  • Items to be cleaned are small, light and delicate so need a gentle cleaning process to prevent damage.
  • Jet washing is probably the preferred cleaning methodology where parts to be cleaned have the following characteristics;
  • Regular outward facing surfaces to be cleaned (no small holes or internal chambers);
  • Large volumes of dirt to be removed;
  • Large volumes of items to be cleaned;
  • Lower cleanliness levels required;
  • Items are heavy and robust enough to not be damaged by high pressure blasting.

What Our Customers Say About us


We approached Sonic Solutions after our parts manufacturers let us down and wasted precious time by supplying oily parts. Not only were they friendly, helpful and happy to rush our parts through - the quality was unbelievable! They arrived back at our factory just in time to not hold up production and we couldn't recommend them highly enough.

Martin Frings


Our company AssetCool found the entire team at Sonic Solutions to be responsive and incredibly supportive of a new project. Their technical knowledge is superb, and they delivered exactly what they promised. We're very happy to recommend them to anyone with ultrasonic cleaning needs, and look forward to working with them again in the future.

Tonia Parris


I reached out with a problem to various companies prior to talking with Sonic Solutions, most were unhelpful. These guys insisted on the first trial being for free! The job was excellent and the turn around time very impressive. We are now setting up a monthly cleaning regime with them. A joy to deal with.
