How to choose
Cleaning tablets
The simplest option. Dissolve a tablet in water, soak your retainer per the product instructions, rinse, done. Low cost and easy to keep as a routine.
Ultrasonic cleaner
A small at-home device that cleans retainers, aligners, and other dental appliances in a water bath. A bigger one-time purchase, useful if you wear a retainer every night.
Case and storage
A ventilated case protects your retainer from damage, pets, and pockets. Cheap, practical, and the item most people lose first.
What matters when comparing
Compatibility: the product page should mention retainers or clear aligners
Size: the tank or case must fit your retainer without bending it
Your routine: tablets for soaking, a device if you want a repeatable daily cycle
Warranty and returns for devices
Delivery to your country and total cost in EUR at checkout

Your retainer care routine
Rinse after every use Rinse with cool or lukewarm water each time you take the retainer out.
Clean regularly Use tablets or an ultrasonic cleaner per the product's own instructions.
Store it dry, in a case Keep the retainer in a ventilated case when it is not in your mouth.
Avoid heat and hot water Heat can distort the material and ruin the fit. No boiling, no dishwasher, no car dashboard.
Replace damaged or loose retainers A cracked, worn, or loose retainer cannot do its job. Order a replacement instead of pushing through.
Retainer care FAQ
Only if the product states it is compatible with retainers or clear aligners. If it does, follow the product's instructions exactly.
No. Treat an ultrasonic cleaner as one part of your routine. Keep rinsing after use and cleaning regularly as the base habit.
Avoid hot water unless the appliance or cleaning product instructions specifically say otherwise. Heat can permanently distort the retainer.
If it is cracked, loose, heavily worn, smells persistently after cleaning, or no longer fits well. Keepers makes replacement retainers from your 3D scan, so ordering a new one is simple.
