Retainers can become a bit grungy over time since they are exposed to any food particles or germs in your mouth. While a quick rinse might be enough to keep your retainer feeling and looking fresh most of the time, sometimes you need something a bit stronger than water. You can use Arm & Hammer baking soda to clean and deodorize your retainer safely in as little time as it takes you to brush your teeth.

Items you will need

  • 2 tsp. of baking soda
  • 2 tsp. of water
  • Toothbrush
  • Running water
Step 1

Combine 2 tsp. of Arm & Hammer baking soda and 2 tsp. of water to form a paste.

Step 2

Dip your damp toothbrush into the baking soda paste.

Step 3

Scrub your dirty retainer with the toothbrush and baking soda paste.

Step 4

Rinse your retainer under running water to remove all of the baking soda.


  • Mix 2 tsp. of Arm & Hammer baking soda into 1 cup of warm water and use this mixture to soak your retainer for about 10 to 15 minutes. The Arm & Hammer website recommends soaking your retainer after each use to keep it fresh and clean.
