Yes, 42kHz is the medical-standard frequency. It is powerful enough to remove biofilm but gentle enough to not cause structural damage or micro-cracks in clear aligners like Invisalign, traditional retainers, or dentures.

Correct. OsicClear is designed for chemical-free operation using plain water. The combination of ultrasonic cavitation and UVC light handles both physical cleaning and biological sanitisation. You can add a drop of mild detergent for a minty scent if desired, but it isn't necessary for hygiene.

We recommend a 5-minute daily cycle to maintain oral hygiene and prevent plaque buildup. For older appliances or heavy staining, use the 10-minute deep cleaning cycle once or twice a week.

OsicClear operates with a low hum, typical of high-frequency ultrasonic devices. It is quiet enough to use in the bathroom without disturbing others, and significantly quieter than older industrial ultrasonic cleaners.

It is perfect for jewelry (gold, silver, diamonds), night guards, mouthguards, glasses, waterproof watches, razors, and even metal coins. Avoid using it for porous gemstones like opals or pearls.

Simply wipe the stainless steel tank with a soft cloth after each use. Periodically run a cycle with a mixture of water and a dash of vinegar to prevent mineral scaling if you live in a hard-water area.
