How Does Ultrasonic Cleaning Work?

Ultrasonic cleaning uses high-frequency sound waves to generate microscopic bubbles in the cleaning solution. These bubbles rapidly collapse, creating a powerful cleaning action that removes contaminants from even the most intricate surfaces.

Key benefits include:

  • Non-Abrasive Cleaning: Eliminates the need for scrubbing or harsh chemicals.
  • Deep Penetration: Cleans inside tubes, threads, and hard-to-reach areas.
  • Time-Saving: Allows for ‘switch on and leave’ operation.

Unsure? Contact us below

How do I control the cleaning process?

Most ultrasonic cleaners come with adjustable temperature and timer controls. The temperature can range from 20-80°C, and the cleaning time typically varies from 0-20 minutes, depending on the level of dirt and the type of object being cleaned.

Do I need a cleaning basket?

Yes, using a wire basket (usually sold separately) is recommended. It helps to keep items suspended in the tank, preventing direct contact with the bottom, which improves cleaning efficiency and protects the cleaner.

Can I put multiple items in an ultrasonic cleaner at once?

Yes, but avoid overcrowding. Items should be spaced apart so that the cleaning solution can circulate freely around them for an even clean. Using a wire basket helps to keep items properly positioned.

Can I use tap water in my ultrasonic cleaner?

Yes, but distilled or deionised water is always recommended, especially for delicate items like jewellery or medical tools, as it reduces mineral deposits that could be left behind.

Do ultrasonic cleaners heat the water?

Yes, many of our models include a built-in heating element (20-80°C) to improve cleaning effectiveness, especially for removing grease, oil, and hardened contaminants. Please check the product description

Do your ultrasonic cleaner come with a warranty?

Standard Warranty: All products are guaranteed for one year from the date of purchase (unless otherwise specified).

During the warranty period, we will repair or replace any defective products at no charge (return-to-base warranty), excluding normal wear and tear.

How do I know if an ultrasonic cleaner is right for me?

If you need a fast, effective, and hands-free way to clean delicate or intricate items, an ultrasonic cleaner is a great investment. Consider the size, power, frequency (40KHz is ideal for general use), and heating options before purchasing.

What are internal tank dimensions, and why do they matter?

The internal tank measurements determine the maximum size of objects that can be cleaned. Always check your item dimensions to ensure they fit comfortably in the tank.

What does ultrasonic power mean?

Ultrasonic power (200W) refers to how strong the cleaning waves are. Higher power means stronger vibrations in the water, which create tiny bubbles that clean the dirt off your items. A 200W ultrasonic power is strong enough to clean heavy dirt, but still gentle enough for more delicate items, like jewellery.

What does heater power mean?

Heater power (400W) means the strength of the heater inside the cleaner. The more heater power, the faster the water can get hot. Heating the water helps break down grease and sticky substances faster, so your cleaning job is done quicker and more efficiently.

What is the temperature range, and why does it matter?

The temperature range (0-80°C) tells you how hot the cleaning solution can get. Hotter water helps clean things like grease, oil, or sticky dirt more easily. So, if you need to clean something that's really dirty, you can turn up the heat. On the other hand, if you're cleaning something delicate, you can keep the water cooler to avoid damage.

What does frequency mean?

Frequency (40kHz) refers to the number of sound waves that the ultrasonic cleaner sends out each second. A 40kHz frequency is the most common and means the cleaner can work quickly and effectively without being too rough. It’s great for cleaning delicate things like jewellery but also strong enough for tougher dirt on things like tools.

I'm on my second one of these tanks now, they last me around 3 years of heavy use each, but now I have two I can cannibalise the older unit and Allendale sell most parts as spares. Previously I used a similar chinese-made unit that is near identical. I recommend replacing the cooling fan with a better quality ball bearing unit once out of warranty as they start groaning when the bushings dry out. Apart from that, I've had a couple of circuit boards fail quite badly (the PCB burnt out), but these are easily changed if you have spares or they can be bought here for £30. I tend to run mine for a good two to four hours, three or four days a week. I use a strong non-corrosive detergent solution and the stainless casing does rust over, but can be easily cleaned. The tank itself usually stays rust free, although build up of deposits above the solution level needs removing regulatly. Tank heating does take a long time and apart from very hot summer days, it usually struggles to get past 50°C, no matter how long it's left switched on. I really likd the simple two dial controls and prefer them over the digital type units. This review might sound critical, but at this price I'll definetely buy another if I can't keep mine running.
