Ultrasonic cleaner 49 KHz 27 oz tank
This Metra TUH56332 unit uses 49,836 Hz sound waves to generate microscopic cavitation bubbles that implode and dislodge embedded dirt, oils and residue from small items. The 304 stainless steel tank holds 27 ounces and measures 8.66 x 4.92 x 3.54 inches while weighing 1.6 lbs. Five preset cycles of 90, 180, 280, 380 and 480 seconds let you match the cleaning time to the object. Tap water works for most jobs; a drop of dish soap helps with greasy watch straps.
Limits of 49 KHz ultrasonic cleaning
The high-frequency action is gentle enough for eyeglasses, retainers, dentures, jewellery, coins and small dental appliances, but it cannot clean natural pearls, jade, cracked pieces or any electronic components. Items must be fully submerged and should not touch the tank walls, so very large or oddly shaped objects will not fit. Heavily accumulated grime may require multiple cycles followed by a light wipe rather than a single pass. The cleaner has no heating element, so water temperature depends on what you pour in.
Upgrading from manual brushing or soaking
This machine replaces hand scrubbing, denture tablets and lens wipes for anyone who regularly cleans retainers, glasses, jewellery or small metal parts. The jump is worth it when you need consistent results on intricate surfaces without abrasion, or when you process several items a week and want a repeatable timed cycle. Buyers who only clean an occasional ring or who need to sanitise larger instruments will not benefit from the 27 oz capacity.

Questions about this item
Which 27oz capacity and 5-mode combination should I choose for cleaning both retainers and eyeglasses?
The single 27oz model offers five timed cycles; use the 280s mode for retainers and dentures, and the 90s or 180s modes for eyeglasses placed lenses-up in the 304 stainless steel tank.
What does the 49KHz frequency actually do inside the tank?
It generates 49,836Hz sound waves that create microscopic cavitation bubbles; these implode to blast away embedded dirt and oils from crevices without abrasion, using only tap water or a drop of dish soap.
How does the touch-control interface limit what I can set?
The unit provides five fixed cycles — 90s, 180s, 280s, 380s and 480s — so you select a preset duration rather than adjusting frequency or power; the longest 480s mode suits stubborn residues with warm water and soap.
