How to Clean Your Retainer

1. How to Clean Retainer with a Toothbrush

Your retainer lives in your mouth, so bacteria builds up fast. This makes daily cleaning an absolute necessity! It's how you avoid bad breath, infections, and keep your retainer fitting comfortably.

Just take a few minutes each day to:

  • Gently scrub your retainer with a soft toothbrush and mild soap.

  • Rinse thoroughly with cool or lukewarm water.

3. How to Clean Retainers with Baking Soda

Baking soda is a handy cleaning agent for many things – including your retainer! It's gentle yet effective at removing buildup and neutralizing odors. 

Here's how to do it:

What You'll Need:

  • Baking soda

  • Lukewarm water

  • Soft-bristled toothbrush

  • Clean container


  1. Mix Your Solution: Add 1 teaspoon of baking soda with about 1/2 cup of lukewarm water. Mix until the baking soda dissolves.

  2. Soak Your Retainer: leave your retainer in the baking soda solution and let it soak for 15-20 minutes.

  3. Gentle Scrub: After soaking, use a soft-bristled toothbrush to gently scrub away any remaining residue. Pay attention to nooks and crannies.

  4. Rinse Thoroughly: Rinse your retainer well under cool or lukewarm water to remove all traces of baking soda.

Important Notes

  • Not a Daily Staple: While baking soda is great, overuse can make some retainers cloudy. Stick to using it 1-2 times a week for a deep clean.

  • Talk to Your Orthodontist: Always check with your orthodontist before using any new cleaning method – they can make sure it's safe for your specific retainer type.

4. How to Clean Your Retainers with Vinegar

Vinegar is a natural cleaner known for its antibacterial properties. Here's how it can give your retainer a fresh, deep clean – but caution is needed!

What You'll Need:

  • White vinegar

  • Lukewarm water

  • Soft-bristled toothbrush

  • Clean container


  1. Dilute the Vinegar: Create a solution of equal parts white distilled vinegar and lukewarm water. Avoid using hot water, as this can damage some retainer materials.

  2. Soak Time: Submerge your retainer in the vinegar solution and let it sit for 15-30 minutes. Do not soak for longer.

  3. Brush Lightly: If any buildup persists after soaking, very gently brush with a soft-bristled toothbrush.

  4. Rinse, Rinse, Rinse: Thoroughly rinse your retainer with cool or lukewarm water multiple times to remove any remaining vinegar taste or residue.

Important Notes

  • Occasional Use Only: Prolonged or frequent vinegar soaks can weaken certain retainers. It's best for occasional deep cleaning, rather than routine maintenance.

  • Not for Everyone: Always consult your orthodontist before using vinegar to ensure it's appropriate for the material of your retainer.

5. How to Clean Retainer with Hydrogen Peroxide

Hydrogen peroxide has cleaning and disinfecting properties, but it's important to use it carefully on retainers.  Here's a breakdown, with safety notes:

What You'll Need:

  • 3% Hydrogen peroxide (standard household strength)

  • Lukewarm water

  • Soft-bristled toothbrush

  • Clean container


  1. Dilute Thoroughly: Create a solution with equal parts 3% hydrogen peroxide and lukewarm water. Never use undiluted hydrogen peroxide.

  2. Short Soak: Submerge your retainer in the solution for no more than 10 minutes. Extended soaking can cause damage.

  3. Brush Gently: If needed, use a soft-bristled toothbrush to lightly remove any remaining buildup. Avoid harsh scrubbing.

  4. Rinse Well: Rinse your retainer multiple times with cool or lukewarm water to remove all traces of hydrogen peroxide.

Important Notes

  • EXTREME CAUTION: Many orthodontic experts strongly advise against using hydrogen peroxide on retainers at all. The risks of material discoloration, weakening, and even changes to fit outweigh the potential benefits.

6. How to Clean Retainer with an Ultrasonic Cleaner

Ultrasonic cleaners are small devices that use ultrasonic waves to quickly and deeply clean items like jewelry and now, retainers! Here's how to use one for a sparkling clean retainer:

What You'll Need:

  • Ultrasonic cleaner

  • Water (Distilled is best, but tap can work depending on your cleaner's instructions)

  • Mild soap or an orthodontic-approved retainer cleaner

  • Soft-bristled toothbrush


  1. Fill the Tank: Fill the ultrasonic cleaner tank with water according to the manufacturer's instructions.

  2. Add Cleaner: Add a small amount of mild soap or a specialized retainer cleaner solution to the water.

  3. Submerge Your Retainer: Gently place your retainer in the tank, ensuring it's fully submerged.

  4. Set the Timer: Run the ultrasonic cleaner for the recommended time (usually 3-5 minutes).

  5. Brush and Rinse: For extra cleaning, gently brush your retainer with a soft-bristled toothbrush after the ultrasonic cycle. Rinse well with cool or lukewarm water.

Important Note:

  • Cleaner Compatibility: Make sure your ultrasonic cleaner is safe for use with retainers. Most are, but double-checking is wise.

7. How to Clean Retainer with Mouthwash

Mouthwash seems convenient for your retainer too, right?  While it can freshen in a pinch, there are reasons to be cautious.

What You'll Need:

  • Alcohol-free mouthwash

  • Lukewarm water

  • Clean container


  1. Dilute, Dilute! Create a solution of equal parts mouthwash and lukewarm water. Alcohol-free is crucial, as alcohol can damage retainers.

  2. Quick Soak: Soak your retainer for no more than 5-10 minutes. Prolonged soaking may cause staining or weaken the material.

  3. Rinse Thoroughly: Rinse your retainer multiple times under cool or lukewarm water to ensure all mouthwash residue is removed.

Important Notes:

  • Not For Daily Use: Mouthwash isn't designed for retainer materials and can impact color or durability over time.

  • Freshness Only: It can temporarily reduce odor, but won't remove significant buildup or tackle bacteria the way specialized cleansers do.

Retainer Care: Crucial Things to Avoid

To keep your retainer in top shape and working perfectly, here are some key things to avoid:

  • Hot Water: Never use hot or boiling water for cleaning or rinsing your retainer. This can warp and damage the material, ruining the fit.

  • Household Cleaners: Harsh chemicals like bleach, abrasive cleaners, or even standard toothpaste can be detrimental to your retainer. Stick to gentler options.

  • Alcohol-Based Products: Avoid using mouthwash with alcohol, hand sanitizer, or similar products – they can discolor and degrade the retainer.

  • Putting it Directly in Your Pocket/Purse: This may seem quick, but your retainer will collect lint, dirt, and can break easily. Always use an aligner protective case.

  • Letting it Dry Out A dried-out retainer becomes brittle and may crack. If not in use, keep it moist inside its case.


Hopefully, by now, you have a better understanding of how to clean your retainer!
