Editor's Pick: Just drop your removed retainers and clear aligners in, add water, and press once to start. The 42kHz frequency reaches into the tiny crevices on the inside of aligners, shaking out residue your toothbrush can't reach. Choose from three timer settings, and it automatically shuts off when done, so you don't have to wait around. After use, simply rinse the body with water. It's IPX7 waterproof, and it runs quietly enough to keep in your bedroom at night without disturbing you.
