Why Choose Ultrasonic Cleaning?
Traditional cleaning methods like scrubbing or soaking can miss hidden grime and risk damaging delicate surfaces. Ultrasonic cleaning works by creating high-frequency sound waves in liquid, producing millions of tiny cavitation bubbles that implode on contact with surfaces — lifting away contaminants at a microscopic level without physical abrasion. It's the same technology trusted by jewellers, dentists, laboratories, and watchmakers worldwide.

Frequently Asked Questions
Q: What can I clean with this 2.5L ultrasonic cleaner?
A: This ultrasonic cleaner is versatile enough to handle jewellery, eyeglasses, watch parts, dental tools, coins, electronic components, lab glassware, keys, and many other small hard-surface items. It's suitable for household, commercial, clinic, hotel, and laboratory settings.
Q: How long does an ultrasonic cleaning cycle take?
A: The digital timer allows you to set cycles anywhere from 0 to 8 minutes. A standard cleaning cycle is 180 seconds (3 minutes), which is sufficient for most everyday items. Heavily soiled items may benefit from a longer cycle or a repeat run.
Q: Do I need special cleaning solution, or can I use plain water?
A: Plain water works for many items, but adding a small amount of mild dish soap or a purpose-made ultrasonic cleaning concentrate can improve results — particularly for greasy or heavily soiled parts. Always check that your chosen solution is compatible with the item being cleaned.
Q: What voltage does this ultrasonic cleaner require?
A: This unit operates at 220V. Please ensure your power supply is compatible before use. If you are in a 110V region, you will need a step-up voltage converter.
Q: Is the tank easy to clean after use?
A: Yes. The inner stainless steel tank is smooth, non-porous, and corrosion-resistant, making it simple to empty, rinse, and wipe down after each use. Regular cleaning of the tank prolongs the life of the unit.
