How to use an ultrasonic retainer cleaner
Zima's steps for its Dental Pod.
Fill the tank to the line
Water up to the fill mark. Zima
Put the appliance in
Up to two at once; a bulky night guard may need the 190 ml Pro. Zima
Close the lid and press the button
One button, a 5-minute cycle, and an audible buzz, owners say. ZimaOwners
Rinse before you wear it
Lukewarm water, never hot, as the AAO describes; then pour the tank out. AAO
What goes in the water?
A tablet is optional, Zima says, and some other brands' tablets corroded its tank. Zima
Are ultrasonic retainer cleaners worth it?
Good for
- A quick clean on top of the daily brush AAO
- Travel: owners pack small pods Owners
- Two appliances: the Dental Pod holds two Zima
Think twice about
- Old yellowing: owners say it stays Owners
- Skipping the brush: the daily brush still applies AAO
- A pacemaker: read the makers' warnings below ZimaAlign
A 2019 study in The Angle Orthodontist tested eight cleaning methods and found none ideal for clear retainer material.
Safety, regulation and how to read a UV claim
Before you plug one in
- Pacemaker? Zima says ask your physician first. Align: "Do not use the Ultrasonic Cleaner if you have a pacemaker."
- Magnasonic's manual: never run it without liquid in the tank.
- Sonic Odyssey's lid is not watertight, a reviewer notes.
How the FDA classes them
- Mechanical denture cleaners: Class I (21 CFR 872.3530).
- UV chamber disinfection devices: Class II (21 CFR 880.6600).

Retainer cleaner machine questions
How do you use an ultrasonic retainer cleaner?
Zima's directions for its Dental Pod: fill the tank to the line with water (a cleaning tablet is optional), put the appliance in, close the lid and press the button for the 5-minute cycle, then rinse the appliance. Other makers' steps differ, so follow the ones for your cleaner.
How often should you use an ultrasonic retainer cleaner?
The AAO describes a rinse every time the retainer comes out, a brush once a day and a weekly soak, and names ultrasonic cleaners and solutions as one option, on top of the daily brush. How often to run the machine is in your cleaner's own directions.
Do ultrasonic retainer cleaners actually work?
The makers say high-frequency sound in water makes tiny bubbles that loosen buildup, and owners commonly report cleaner appliances than with brushing alone. Several owners also say a machine does not reverse old yellowing or cloudiness.
What do you put in an ultrasonic cleaner with a retainer: water only or a tablet?
Zima says its tablets are optional, recommends one if you wear your appliance for more than 6 hours at a time, and says some other brands' tablets damaged and corroded its tank. Align pairs its cleaner with its own Cleaning Crystals+. Follow your cleaner maker's guidance.
Can I use an ultrasonic jewelry cleaner for my retainer?
Magnasonic markets its MGUC500 for jewelry, eyeglasses and watches, not dental appliances. Check with your orthodontist and the appliance maker's care guide before you use a jewelry cleaner.
Are ultrasonic retainer cleaners worth it compared with tablets?
It depends on the routine. Owners commonly report cleaner appliances than with brushing alone, and a machine still leaves the AAO's daily brush in place. A 2019 study in The Angle Orthodontist that tested eight cleaning methods found none of them ideal for clear retainer material.
Ultrasonic vs UV retainer cleaner: what is the difference?
An ultrasonic cleaner uses sound waves in water to loosen buildup, as the makers describe it. A UV-C chamber shines ultraviolet light, and kill-rate figures such as Sonic Dental's come from the maker's own testing. The FDA classes UV radiation chamber disinfection devices as Class II (21 CFR 880.6600), and Zima argues UV is less effective in cloudy water.
