Invisalign retainers should be cleaned every week in vinegar for 15 minutes if you want to keep them free of bacteria. Afterward, rinse it with distilled water and soak it as usual. 

In exchange for the invisibility and freedom you get with Invisalign aligners, you have to spend a little more time taking care of your orthodontic appliance than someone with traditional metal braces. Also because of the uniqueness of Invisalign aligners, there are special steps you’ll need to take to clean and store your Invisalign aligners correctly.

Can I Clean my Invisalign Aligners at Home? 

You sure can, see our tips below. 

Aligner-Friendly Cleaning Solution

You can buy cleaning solution from Invisalign that was created specifically to work with their products. However, some at-home remedies include: 

• A 20 minute soak in a 3:1 ratio of distilled white vinegar and water
• A 30 minute soak in an equal mixture of hydrogen peroxide and water
• A 60 min soak in a mix of a tablespoon of baking soda and  ½ cup water (this one is helpful if stains/residue begin to appear on your aligners)

Soft-Bristled Toothbrush

After soaking in your prefered cleaning solution, you will need to scrub your Invisalign retainers for remaining solids and to remove any lingering cleaning residue. Your trays are strong enough to arrange your teeth, but an abrasive brush with your typical toothbrush may damage your trays and not allow them to work properly. We recommend getting a separate, soft-bristle brush for cleaning your aligners.

How to Clean Your Invisalign Case?

While you may think of your case as more of a protective measure than a cleansing one, your Invisalign aligner tray case plays an important role in keeping that bacteria we wrote about earlier at bay. When you remove your aligners to eat, make sure to store them in your case. This will limit their exposure to air and reduce the likelihood of bacteria blooming. Your case also provides a perfectly sized soaking vessel.

How Often Do You Need to Clean My Invisalign Aligners?

Like your teeth, Invisalign aligners need to be cleaned everyday in order to best prevent bacterial growth and oral health problems. Ideally, you’d take the time to scrub your retainers each time you remove them. However, we know this is not always possible. So, the cleaning schedule we recommend is once in the morning, when you wake up, and once in the evening, before you go to bed. In between, make sure you rinse your aligner in cold water before replacing it after eating. Remember: just rinsing them after meals is not enough to prevent bacterial build up!

What is the white stuff on my Invisalign?

You could end up with a white film covering your aligners if you don’t regularly clean your Invisalign aligners. This film is called plaque. Orthodontist typically recommend brushing your teeth frequently due to plaque buildup.

How to Store Invisalign Aligners When Not In Use

For your Invisalign aligners to work as intended, you need to be wearing them for as much of the day as possible. However, when you remove your retainers for meals, cleaning, or other activities that may require their removal, be sure to secure them in your Invisalign case, away from hot environments. 

When you receive your next set of Invisalign aligners, we recommend storing them in a cool place and in the packaging they arrive in. This can help minimize misplacing or confusing them with your old retainers.  

Conclusion

While it may seem like a lot laid out in this blog post, cleaning your Invisalign retainers each day takes minimal time. It’s much more beneficial to invest the time over each day of treatment than attempt intense deep cleans only once every so often. Proper care and cleaning of your Invisalign will ensure you maintain your oral health and achieve your ideal smile.
