For a deeper clean, mix lukewarm water with mild dish soap (toothpastes are abrasive and can scratch the retainer's surface). Use a soft toothbrush or denture brush to gently scrub away plaque and other debris. If necessary, use a cotton swab to get into the deepest grooves and ridges on clear plastic retainers.

How do you remove plaque from retainers?

For a light buildup, soak your retainer in distilled water. Avoid tap water as it may contain harmful bacteria or minerals. Use a soft-bristled toothbrush to remove the plaque. For a heavier plaque buildup, soak your retainer in a mixture of baking soda and distilled water.

How can I make my retainers clear again?

To clean a retainer with vinegar, people should create a mixture in a small dish that is half white vinegar and half warm water. The retainer should then be soaked in the mixture for 20 minutes. If the retainer is covered in a film or in mineral deposits, a soft toothbrush can be used to scrub the retainer clean.
