Things You'll Need:
- Water
- Pot or microwaveable bowl
- Food-grade hydrogen peroxide (3% solution)
- Small bowl (large enough to fit mouthpiece)
-
Step 1
Bring a small pot of water to a boil or microwave a bowl of water and bring it to a boil.
-
Step 2
Dip the mouthpiece into the water for just long enough to sterilize, but not long enough to melt. Depending on the thickness of the mouthpiece this could take anywhere from 15 seconds to a minute.
-
Step 3
Take mouthpiece out of water and let it cool and dry.
-
Step 4
Pour hydrogen peroxide into a small bowl.
-
Step 5
Place the mouthpiece into the bowl of hydrogen peroxide. Make sure there is enough hydrogen peroxide to cover the mouthpiece completely. If there are remaining bacteria on the mouthpiece, the mouthpiece will begin to foam.
-
Step 6
Repeat Step 5 with fresh hydrogen peroxide until the mouthpiece no longer foams.
-
Step 7
Rinse the mouthpiece with cold water to wash off all of the remaining hydrogen peroxide.
