Disinfects. Works with the iSonic ultrasonic denture/retainer/appliances cleaners. Fast action. Crystal form, 1 teaspoon per cup of tap water to remove heavy stains. 1 bottle is good for 48 cups with this ratio. Use 1/2 teaspoon in iSonic model F3900, DS180. It can also be used with less concentration for mild/daily cleaning and disinfection.

Much more effective than regular tablets and most other denture cleaners on the market
The second photo shows a 25 year old denture which was never cleaned professionally before. The left side was cleaned with iSonic White Denture/Retainer Cleaning Crystal in the iSonic F3900 for 15 minutes. The right side was not cleaned.

 
Recommended application: to remove stains and buildups from dentures, retainers, sleep apnea appliances, mouth guards and other dental appliances, can be used for mild/daily cleaning and disinfection with reduced concentration as well.
