Ultrasonic cleaning has become a go-to solution for both professionals and home users looking for a fast, effective, and gentle way to clean a wide range of items. From precision engineering workshops and factories to clinics and tattoo parlours, and even hobbyists’ garages, ultrasonic cleaners are trusted for their ability to deliver spotless results without harsh scrubbing or abrasive chemicals.
At the heart of this technology is a process called cavitation, which uses sound waves to clean surfaces thoroughly, even in places you can’t reach with a brush.
How Do Ultrasonic Cleaners Work?
High-Frequency Sound Waves
Inside the cleaner, an electrical generator sends out a high-frequency signal. This activates transducers attached to the tank, creating compression waves in the cleaning fluid. These sound waves typically range from 20 kHz to 400 kHz - lower frequencies are great for tough jobs, while higher ones suit more delicate items.
Cavitation: The Cleaning Powerhouse
The sound waves produce tiny vacuum bubbles in the liquid. When these bubbles collapse, they release intense energy, with pressures up to 20,000 psi and temperatures around 5,000°C (on a microscopic scale!). This action lifts dirt, grease, and other contaminants from surfaces, even in hard-to-reach places.
Deep, Gentle Cleaning
Because ultrasonic cleaning is non-abrasive, it’s ideal for delicate components. The collapsing bubbles clean every surface they touch - including blind holes, crevices, and internal channels - without causing damage.
Tips for Getting the Best Results
To maximise your ultrasonic cleaner’s performance:
- Use the right cleaning solution: Choose one formulated for ultrasonic use to boost cavitation and cleaning power.
- Start with pure water: De-ionised, demineralised, or distilled water is best. Tap water can introduce impurities and reduce effectiveness.
- Keep an eye on temperature: Most cleaning solutions work best between 40°C and 60°C.
- Change the solution regularly: Dirty fluid means dirty results - fresh solution ensures consistent cleaning.
Before and After: The Ultrasonic Difference
Ultrasonic cleaning transforms items from visibly dirty to spotlessly clean, removing even microscopic contaminants. This level of precision is essential in industries like medical, electronics, jewellery, and engineering.
Choosing the Right Cleaning Solution
The cleaning fluid you use makes a big difference. Here are a few examples:
- Engine parts & carburettors: Use a degreasing solution to break down oil, grease, and carbon deposits.
- Jewellery: Opt for gentle, jewellery-safe cleaners. Avoid cleaning soft or porous stones like opals and pearls - always check with a jeweller first.

What Can I Clean with an Ultrasonic Cleaner?
Ultrasonic cleaners are incredibly versatile. If it’s waterproof or submersible, chances are it can be cleaned ultrasonically! Popular applications include:
- Jewellery: Great for intricate designs - just avoid delicate stones.
- Carburettors & engine parts: Removes built-up grime and grease.
- Dental & veterinary instruments: Achieves medical-grade cleanliness.
- Tattoo equipment: Ensures professional hygiene standards.
- Coins & collectables: Restores shine without damaging fine details.
- Waterproof watches: Cleans inside cases without opening them.
- PCB boards & electronics: Removes flux and residue safely.
- Optical lenses & glasses: Clears smudges and particles without scratching.
- Laboratory glassware: Ideal for precision cleaning in scientific settings.
- 3D printed parts: Removes support material and residue efficiently.
- Airbrushes & spray guns: Keeps nozzles and components clean for consistent performance.
Why Choose Ultrasonic Cleaning?
With over 20 years of experience, we’ve seen ultrasonic cleaning revolutionise workflows across industries. Here’s why it’s a smart choice:
- Saves time and effort compared to manual scrubbing.
- Reaches microscopic crevices for a truly thorough clean.
- Preserves delicate items, thanks to its gentle, non-abrasive action.
Whether you’re a professional or a hobbyist, ultrasonic cleaning offers a reliable, efficient way to keep your tools, parts, and valuables in top condition.
