Woman smiling and holding up an Invisalign aligner.

Modern technology has made straightening your teeth easier than ever, especially with discreet Invisalign® trays.

You’re probably extremely excited to start your orthodontic treatment.

But, wait!

Do you know how to clean Invisalign trays?

In this quick blog, you’ll learn our top four tips on keeping your aligners… This text opens a new tab to the Invisalign website… clear, clean, and durable.

Let’s get started!

1. Use a soft-bristled toothbrush

Use a soft toothbrush to clean out food particles and germs from your trays.

Put a gentle, clear liquid soap on the brush, and using light circular motions, clean the inside and outside of your trays.

Keep in mind:

Only use lukewarm water to rinse out your trays.

Hot water may cause your aligners to deform or lose shape.

2. Don’t leave your aligners exposed to open air

After removing your aligners, you want to train yourself to put them in their case immediately!

Exposing your aligners to open air allows bacteria to form quickly.

If you leave them out for an extended period, remember to thoroughly clean them before putting them back in!

3. Soak your trays with Invisalign crystals

Invisalign crystals… This text opens a new tab to the Invisalign website… are specifically designed to clean your trays without discoloring or warping them in any way!

To use:

  • Fill a container with warm water
  • Pour a packet of the cleaning crystals and stir until it dissolves
  • Place your trays in the solution
  • Soak for 15 minutes
  • Brush and rinse

That’s it!

4. Find at-home cleaning products

You probably have these tools in your cabinet already.

You can clean your Invisalign trays with the following:

  • Hydrogen peroxide
  • Baking soda
  • Distilled white vinegar

Hydrogen peroxide

Hydrogen peroxide removes stains from your trays.

Find a low concentration of peroxide and combine it with warm water.

Then, you’ll want to soak your aligners for around 30 minutes.

After, brush and rinse them before wearing them again.

Baking soda

Baking soda is great for removing stubborn food particles and plaque from your aligners.

Combine a tablespoon of baking soda in one cup of warm water.

Soak your trays for at least 30 minutes, then brush and rinse.

Distilled white vinegar

Keep in mind:

You need to use white vinegar for this method.

Any other type will stain your aligners.

Create a solution that’s 1/4 vinegar and 3/4 warm water.

Then, soak for 15 minutes and proceed to brush and rinse before putting them back in!

Why do I need to clean my Invisalign trays?

Invisalign trays are made to be clear.

When you don’t clean them, food particles and plaque may build up on the trays, giving them a cloudy or discolored look.


Dirty aligners lead to tooth decay, staining, and bad breath.

Keep your aligners clean for the best treatment possible.
