Tablets and crystals questions

How long do you soak a retainer in a cleaning tablet?

Each label differs: Retainer Brite says 15 minutes in warm, not hot, water; Efferdent Retainer Clean & Bright says 3 minutes in very warm water; Invisalign Cleaning Crystals say at least 15 minutes in about 100 ml of warm water.

Can you use retainer cleaning tablets every day?

Retainer Brite's directions say 'Use daily for best results', and Efferdent describes its tablets as safe for daily use. The AAO describes a weekly soak of 10 to 20 minutes.

Can you put a cleaning tablet in an ultrasonic cleaner?

Neither tablet label covers it. Zima says some other brands' tablets damaged and corroded its tank, so follow your cleaner maker's guidance.
