I tried the battery powered retainer cleaner and I love it!

I used the cleaner on a dirty veneer, it came out spotless. I've never seen a cleaner do it that good before.

Common questions
Still got a question? Get in touch and we'll help.
What can Sonic Spa Go clean?
Clear aligners, retainers (including ones with metal parts), mouth guards, bite guards, dentures, whitening trays, sleep apnea devices and other removable oral appliances.
Will it damage my appliance?
No. Ultrasonic cleaning has been used in laboratories and dental practices for over 60 years because it's both effective and gentle.
How does ultrasonic cleaning work?
Sonic Spa Go sends ultrasonic sound waves through the water. These create millions of tiny bubbles that gently lift dirt and bacteria out of every groove, without any scrubbing. At the same time, UVC light shines down from the lid. Read the research
Do I need Boostab tablets?
No. Sonic Spa Go cleans with just water. Add a Boostab tablet whenever you want an extra-deep clean and extra freshness.
How long does the battery last?
Around 10 cleans on a single charge, which is about 5 days if you clean twice a day. A full charge takes around 1.5 hours, and because it's cordless, it's easy to take with you when you travel.
Real people. Real results.
Dropped it twice, got water all over it, used it almost every night for ten months. Still works perfectly and my retainers look good as new.
Love the cordless cleaner. Now bought two, one for my son at uni and one for my daughter. Charge lasts well over a week.
Cleans my dentures better in three minutes than an hour in my other ultrasonic cleaner. Highly recommend.
Very easy to use and has cleaned retainers properly.
So clean, and easy to use.
Compact and cordless, so it's easy to use daily. The cleaning is thorough and everything feels really fresh afterwards. Peace of mind that my retainers are properly clean without the effort.
