How To Clean Night Guard With Vinegar. After you’ve soaked your appliance in vinegar, rinse the bowl and the appliance. Mix mouthwash with water and soak the night guard for 30 minutes.
In order to use vinegar for mouth guard cleaning, you should place your mouth guard in a metal bowl or cup and pour vinegar over the device, ensuring that its totally covered. Once you are done rinsing and scrubbing, you must thoroughly dry your night guard before storage. This is when you’ll want to use a denture product specifically labeled for use with partials (typically dentures with metal parts).
If chemicals aren’t your thing, you can clean your night guard naturally.
If you don’t have mouthwash handy, hydrogen peroxide will work too. Add the mouth guard and dilute with water. Dry it with a soft, clean cloth. Rinse your mouth guard or night guard under lukewarm tap water.
