If you wear Invisalign, keeping your aligners clean is just as important as wearing them for the recommended time each day. To clean Invisalign, gently brush your aligners with a soft-bristled toothbrush and rinse them in lukewarm water after every meal. For deeper cleaning, use a specialized cleaning solution or Invisalign Cleaning Crystals to remove bacteria and buildup. Avoid using hot water, harsh cleaning products, or toothpaste, as these can damage the trays.
Clean aligners not only look better but also prevent odors, discoloration, and bacterial buildup that could affect your oral health. Below, you’ll learn the best ways to clean Invisalign retainers, when to use hydrogen peroxide or baking soda, and what common mistakes to avoid.
The most effective way to clean Invisalign trays is to incorporate them into your daily oral hygiene routine. Each morning and night, remove your aligners and rinse them under lukewarm water. Then, use a soft toothbrush (different from your regular toothbrush) to gently clean both the inside and outside surfaces. Avoid using toothpaste, as it can be too abrasive and leave scratches that trap bacteria.
After cleaning, rinse the trays again and store them in their case when not in use. It’s also important to brush and floss your teeth before putting your aligners back in. This prevents food particles and plaque from getting trapped, which can cause bad breath and cavities over time.
A professional-grade cleaning solution can help maintain the clarity and freshness of your aligners. Many orthodontists recommend soaking Invisalign aligners once a day or every few days in a mild solution specifically made for aligners or retainers.
You can purchase branded cleaners, such as Invisalign Cleaning Crystals, or other products labeled as retainer cleaning solutions. To use them, dissolve the cleaning tablet or crystals in a cup of warm (not hot) water and soak your trays for about 15 minutes. After washing, rinse the aligners thoroughly under running water before reinserting them.
This process removes bacteria and plaque buildup that brushing alone may not be able to eliminate. Regular soaking also prevents odor and staining, keeping your trays clear and virtually invisible.
Hydrogen peroxide is a convenient and affordable option for cleaning Invisalign at home. It works as a natural disinfectant, killing bacteria and eliminating odors. However, it should be used correctly to avoid damaging your trays.
To clean Invisalign retainers using hydrogen peroxide, mix equal parts of 3% hydrogen peroxide and lukewarm water in a glass or bowl. Soak your aligners for about 15–20 minutes. Afterward, rinse them thoroughly with clean water to remove any residue.
While hydrogen peroxide is effective, it shouldn’t replace your daily brushing routine or professional cleaning solutions. Overuse can cause the aligners to lose their shine or become cloudy, so it’s best to use this method a few times per week.
Baking soda is another simple and safe way to disinfect and deodorize Invisalign aligners. Its mild abrasive quality helps remove plaque without scratching the trays, and it’s especially helpful if your aligners have developed an unpleasant odor.
To clean Invisalign retainers with baking soda, mix one tablespoon of baking soda with half a cup of water. Stir the mixture until the baking soda dissolves, then soak your aligners for about 30 minutes. After washing, brush them gently and rinse thoroughly with lukewarm water.
Baking soda is ideal for those who prefer a natural cleaning method and want to avoid chemical-based cleaners. However, it should not be combined with vinegar or hydrogen peroxide simultaneously, as this can cause unwanted reactions.
Invisalign Cleaning Crystals are specially designed by the manufacturer to keep trays clear and hygienic. They are made from ingredients that dissolve plaque and bacteria without damaging the plastic material.
Using Cleaning Crystals is easy and quick. Dissolve one packet in a cup of warm water and soak your aligners for about 15 minutes. The solution changes color as it works, helping you see the cleaning process. Once finished, rinse your aligners under water before putting them back in.
Unlike household alternatives, Cleaning Crystals are formulated specifically for Invisalign aligners, so they’re less likely to cause discoloration or affect the fit of your trays. Regular use helps maintain transparency, comfort, and hygiene throughout your treatment.
Hot water might seem like a quick way to kill germs, but it can warp or distort your aligners. Invisalign trays are made from a specialized thermoplastic material that softens under high heat, so always use cool or lukewarm water when cleaning them.
Similarly, avoid harsh cleaning products, such as mouthwash, bleach, or household detergents. These can damage the surface of your trays, making them cloudy and uncomfortable to wear. Even alcohol-based mouthwashes can dry out the plastic, leading to cracks or brittleness over time.
If you want to freshen up your trays between deep cleans, simply rinse them under cool water and brush gently. Consistency and gentle care are key to maintaining their shape and clarity.
If you prefer ready-to-use options, several cleaning products are specifically designed for use with Invisalign and other clear aligners. These include tablets, foams, and sprays that remove plaque and kill bacteria effectively without harming the trays.
Brands like Invisalign Cleaning Crystals, Retainer Brite, and Steraligner are popular choices. Foaming cleaners can be sprayed directly onto the aligners, left for a few minutes, and then rinsed off. Cleaning tablets and powders are typically dissolved in water for soaking.
Always check the product instructions before use and ensure it’s labeled as safe for clear aligners. Using approved cleaning products ensures your trays remain in good condition and last through the full course of your treatment.
Even with good intentions, it’s easy to make mistakes that could damage your aligners or reduce their effectiveness. One common mistake is using toothpaste or abrasive brushes, which can create small scratches that trap bacteria. Another is soaking trays in mouthwash or hot water, which can cause discoloration and warping.
Some people forget to clean their storage case, which can harbor bacteria and transfer them to the trays. Make sure to wash your case daily with soap and water, and allow it to air dry completely before storing your aligners.
Additionally, never eat or drink anything other than water while wearing your aligners. Foods and colored drinks can stain the trays and increase the risk of cavities. Proper care ensures your Invisalign aligners stay clear, comfortable, and hygienic throughout your orthodontic treatment.
To keep your Invisalign aligners in top condition, clean them every time you brush your teeth. Always rinse them after eating or drinking, even if you can’t brush right away. Store them in their protective case whenever they’re not in your mouth to prevent exposure to bacteria or loss.
Replace your aligners according to your orthodontist’s schedule. Even with perfect cleaning, trays are designed for short-term use and must be changed regularly to stay effective. Maintaining good oral hygiene – brushing twice a day and flossing once daily – will also help your aligners stay cleaner and your smile healthier.
Learning how to clean Invisalign properly is an essential part of your orthodontic treatment. With simple steps – rinsing in lukewarm water, brushing gently, and soaking with a safe cleaning solution or Invisalign Cleaning Crystals – you can keep your trays clear, fresh, and comfortable.
Avoid using hot water or harsh cleaning products, and follow your orthodontist’s care recommendations for the best results. Whether you use hydrogen peroxide, baking soda, or specialized cleaning products, consistency is what matters most. Clean aligners lead to better oral health, fresher breath, and a smoother path toward your ideal smile.
