How to Clean Invisalign – Essential Tips, Dos & Don’ts, & FAQs!

How to Clean Invisalign

If you are undergoing Invisalign treatment, you probably know that keeping your Invisalign trays clean is essential for maintaining good oral hygiene. It is also crucial for ensuring effective treatment. But do you know how to clean Invisalign?

This blog post explores correct methods to clean Invisalign retainers and answers some frequently asked questions about their maintenance. Some dos and don’ts are also mentioned here for your further help. So, let’s dive in!

Why Should You Clean Invisalign?

Before getting to know how to clean your Invisalign aligners, let’s clarify why it is so important! Keeping your Invisalign trays clean is essential for proper dental hygiene and reducing bacteria accumulation. When your aligners are clean, they feel more comfortable in your mouth.

Furthermore, clean Invisalign lessens the likelihood of developing foul breath. Most importantly, transparent aligners must remain clear in order to be inconspicuous and avoid attracting unwanted attention. Regular cleaning can also help your aligners stay longer and function well during your treatment.

So, keeping Invisalign clean is essential not only for appearance but also for the health of your smile!

What are the Most Efficient Practices for Cleaning Invisalign?

Let’s dive into some of the best practices for cleaning your Invisalign aligners and keeping them in tip-top shape!

  • Everyday Cleaning Routine: It is critical to integrate everyday cleaning into your dental care regimen. After you’ve removed your aligners, rinse them with lukewarm water to remove any saliva or food particles.
  • Brushing Your Aligners: Brush your Invisalign aligners gently, just as you would your teeth. However, it is critical to use a soft-bristled toothbrush and clear, antibacterial soap.
  • Soak Them Clean: In addition to regular washing and brushing, soaking your Invisalign aligners can help keep them clear and clean. There are specifically prepared cleaning crystals and solutions that may successfully eliminate residual odors and stains.
  • Avoid Staining Agents: To maintain your Invisalign aligners in good condition, avoid drinking staining beverages such as coffee, tea, or red wine while wearing them. These might discolor the aligners, making them more visible in your mouth.
  • Store Them Properly: When you don’t wear your aligners, be sure to store them in their case. This prevents accidental damage, loss, or exposure to outside elements that could compromise their cleanliness.
  • Regular Check-ins With Your Orthodontist: It’s crucial to attend your scheduled orthodontic appointments and follow up with your orthodontist if you encounter any issues with your Invisalign aligners.

6 Proven Ways to Clean Invisalign

Just like your teeth, Invisalign trays can accumulate bacteria, plaque, and stains over time. Regular cleaning helps remove bacteria and plaque and keeps your aligners clear, comfortable, and odor-free. Check out the 6 most effective ways of cleaning Invisalign trays.

  1. Invisalign Cleaning Crystal

    One of the most popular, convenient, and recommended methods is to clean Invisalign with Invisalign Cleaning Crystals. These crystals are specifically designed to remove plaque, tartar, and other debris that can accumulate on the trays.
    All you need to do is dissolve the crystals in water as instructed and soak your trays for the recommended time. This method is simple, effective, and helps maintain the clarity and freshness of your Invisalign trays.

  2. Invisalign Cleaning Spray and Foam

    Another excellent option is using Invisalign Cleaning Spray and Foam. It is formulated to kill bacteria and remove stains from your trays. The method is simple – spray or apply the foam onto your trays, brush gently, and rinse thoroughly.
    This method lets you properly clean Invisalign while leaving them with a pleasant, minty-fresh scent. Plus, it’s the perfect way to clean stained Invisalign.

  3. Distilled White Vinegar

    If you notice stubborn tartar or hard buildup on your Invisalign trays, distilled white vinegar can be your go-to solution. It has natural antimicrobial properties that help kill bacteria and dissolve tough deposits. To clean Invisalign with vinegar, dilute the vinegar with equal water and soak your trays for about 15-30 minutes.
    Afterward, give them a gentle scrub with a soft toothbrush and rinse thoroughly to remove any residual vinegar taste.

  4. Hydrogen Peroxide

    Hydrogen peroxide can also effectively tackle stubborn stains on your Invisalign trays. It acts as a bleaching agent, helping to whiten and brighten your trays. But how to clean Invisalign with hydrogen peroxide? It’s pretty simple. Create a mixture of equal parts hydrogen peroxide and water, then soak your trays for about 15-20 minutes.
    Then give them a gentle brush and rinse thoroughly. Remember not to use hydrogen peroxide on colored or patterned trays, which may cause discoloration.

  5. Clear Hand Soap

    Using clear hand soap can be simple and effective for regular daily cleaning of Invisalign retainers. Just lather up a small amount of clear hand soap on your fingers, gently rub it onto your trays, and rinse thoroughly.
    However, avoid using soaps with added fragrances or moisturizers, which may leave residue on the trays.

  6. Baking Soda

    Baking soda is a versatile cleaning agent that can also be used to clean Invisalign cases along with trays. Create a paste by mixing baking soda with water, then gently brush your trays with the paste using a soft toothbrush.
    Rinse thoroughly after brushing. Baking soda effectively combats odors and helps remove stains.

What are Major Dos and Don’ts for Cleaning Your Invisalign Aligners?

While it’s super important to maintain good oral hygiene during your orthodontic treatment, it’s equally crucial to take proper care of your Invisalign trays to ensure they stay crystal clear and free from bacteria. So, let’s dive into the dos and don’ts of cleaning your Invisalign trays!


  • Rinse Them Frequently: After withdrawing the trays from your mouth, thoroughly rinse them with lukewarm water. This easy action helps to eliminate saliva and other food particles that may be left on the trays.
  • Store Them Properly: When you remove your trays, make sure to store them in their designated case. This helps to protect them from damage and prevents them from getting lost or accidentally thrown away.
  • Brush Gently: Invisalign trays, like your teeth, require a good brush to keep clean. To gently scrub the trays, use a soft-bristled toothbrush and mild, clear antibacterial soap. Avoid using colored or strongly scented soaps, as they might leave residue and alter the flavor of your trays.
  • Keep Them Away From Hot Water: Avoid using hot water to clean your Invisalign trays, as it can warp the plastic and affect the fit.
  • Soak Them: To keep your trays crystal clear, immerse them in specialized Invisalign cleaning crystals or denture cleaner. Follow the directions given by your orthodontist or product maker.


  • Use Toothpaste: Using toothpaste to clean your Invisalign trays is a major no-no. Toothpaste is abrasive and can scrape the surface of the trays, making them more prone to bacterial growth.
  • Use Strong Chemicals: Avoid using strong chemicals or bleach to clean your trays, as these might harm the plastic and threaten its integrity.
  • Eat or Drink While Wearing Them: It’s tempting to keep your trays in while enjoying a snack or beverage. But eating and drinking with your trays can cause discoloration and bacterial development, as well as severe damage. So, it’s always better to take them out first.
  • Forget to Brush Your Teeth: Maintaining good oral hygiene goes hand in hand with keeping your Invisalign trays clean. Make sure to brush and floss your teeth after eating before putting your trays back in.
  • Neglect Cleaning: The last thing you want is a buildup of plaque and bacteria on your Invisalign trays. Regular cleaning and care are essential for keeping them in top-notch condition.

To conclude, taking care of your Invisalign aligners doesn’t have to be a hassle. A little bit of TLC goes a long way! Following the tried-and-true procedures suggested in this article allows you to clean and maintain your Invisalign aligners efficiently.

Remember, consistency is essential! So, include these cleaning strategies in your everyday practice. Here’s to a bright and healthy smile with your freshly cleaned Invisalign!
