5 Steps for Success

Step 1

Rinse the retainer with lukewarm water: Before cleaning your plastic retainer, it’s important to rinse it in lukewarm water to remove any loose debris.

Step 2

Use a non-abrasive cleaner: Choose a non-abrasive cleaner, such as a gentle soap or a specially-formulated retainer cleaner. Avoid using regular toothpaste, as it can be abrasive and scratch your retainer.
