How it works
1. Bubbles form. Ultrasonic waves create millions of microscopic bubbles throughout the water.
2. Bubbles collapse. They implode against every surface of your appliance, thousands of times a second, including the grooves a bristle can't reach.
3. Buildup lifts away. Plaque, film and staining release and suspend in the water — which is exactly why it changes colour.
Five minutes vs. the old way
A toothbrush cleans what it can reach. A retainer is a cast of your teeth — its whole shape is grooves a bristle can't enter.

Why we built this
Most people clean a retainer by rinsing it and giving it a scrub. It comes out looking clean, so the assumption is that it is.
It isn't. A retainer is a cast of your teeth, which means its entire surface is grooves and undercuts shaped exactly like the gaps a bristle can't enter. Run one through five minutes of ultrasonic cleaning and the water tells you the truth.
We sell one thing and we're specific about what it does. It's a cleaner, not a steriliser. It works with plain water and better with a tablet — which we don't sell and don't mark up. And it costs $59 against the $99.99 the biggest name in aligners charges for theirs.
Everything you need to know
Does it sterilise my retainer?
No — and be sceptical of anything in this category claiming it does. It's a cleaner. It removes plaque, film, staining and debris from surfaces a brush can't reach. That's a different claim, and it's the one we can stand behind.
How do I know it's working?
The water. It goes cloudy after the first cycle, and that's the buildup lifting off your appliance. You'll see it on day one.
Can I use it with Invisalign aligners?
It cleans clear aligners, including Invisalign trays. To be straight with you: Align Technology doesn't officially endorse third-party ultrasonic cleaners, so we're not going to imply that they do.
Do I need cleaning tablets?
It works with plain water and works better with a tablet. We don't sell tablets and we don't mark them up — any pharmacy denture or retainer tablet does the job for around ten dollars a month's supply.
One tip from experience: if you're using a tablet, fill the tank slightly below the max line. Tablets fizz, and a full tank can bubble over.
What are the four modes?
Quick clean — 5 minutes of ultrasonic with UV, for daily maintenance.
Deep clean — 10 minutes of pulsed ultrasonic with UV, for stubborn buildup.
Ultrasonic only — 10 minutes, for delicate items.
UV only — 15 minutes, no vibration.
Switch between them with one touch. A digital countdown shows the time remaining.
What shouldn't go in it?
Emeralds, opals and pearls — ultrasonic cleaning can damage all three permanently, along with anything on worn or antique settings. Use room-temperature water only; heat combined with vibration is what warps thermoplastic trays.
Anything I should know before the first use?
Always close the lid before starting a cycle — the UV lamps switch off automatically when it's opened, and you shouldn't expose eyes or skin to UV light. Keep it out of reach of children, and don't run a cracked or broken appliance in it.
Fill to the line with room-temperature water, never hot.
How often should I use it?
Once a day. More isn't better — repeated ultrasonic cleaning over time can leave microscopic scratching that makes clear appliances look cloudy.
