So, how should you clean an Invisalign case? Dr. Boris Pinhasov, a board-certified orthodontist at BP Smiles NY, says, “The case can be cleaned using a toothbrush and a bit of toothpaste. Simply brush and rinse the case, and it will be clean.”

What Are the Safe Methods of Cleaning Invisalign Cases?
Regular Brushing
Use a soft-bristled toothbrush and orthodontist-suggested toothpaste for everyday cleaning. Brush gently, focus on the corners and crevices to ensure thorough cleaning.
Mild Wash
Soak your Invisalign tray in soapy water for 15 minutes. Only use scent-free, mild soap and warm water to wash thoroughly and remove any remaining residue.
Thorough cleaning
For any hard plaque layers that won’t go with brushing, apply an orthodontist-suggested denture cleaner solution. Invisalign cleaning crystals and white vinegar solution work great for a deeper wash.
Stain Removal
When your Invisalign case turns yellow or gets stained, mild dish soap or an Invisalign-approved cleaning solution can help restore its clarity. For stubborn stains, soak the case for up to 30 minutes.
How to Remove Stains from Your Invisalign Case and Trays
Stains on your Invisalign case usually come from coffee, tea, red wine, tobacco, or colored mouthwash residue. The good news: most stains lift with a 15-minute soak. Here are the safest stain-removal methods Dr. Pinhasov recommends:
- Mild dish soap soak (first try): Fill the case with warm water and 2 to 3 drops of dish soap. Soak 15 minutes, scrub gently with a soft toothbrush, rinse thoroughly.
- Baking soda paste (moderate stains): Make a paste with 1 teaspoon baking soda and a few drops of water. Apply with a soft toothbrush, scrub in circles, rinse for 60 seconds.
- White vinegar soak (set-in stains): 1 part white vinegar to 3 parts warm water. Soak 20 to 30 minutes, scrub, rinse for 2 minutes to remove all vinegar smell.
- Hydrogen peroxide rinse (deep yellow stains): 3% hydrogen peroxide diluted 1:1 with water. Soak 10 minutes maximum to avoid material damage. Rinse thoroughly.
Avoid: bleach, alcohol-based mouthwash, hot water (over 120F), abrasive scrubbing pads, or denture-cleaning tablets with persulfate. These will damage the plastic or leave a chemical residue. If your case stays yellow after these methods, it is time to replace it. Same rules apply to your Invisalign trays themselves; rinse them every time you remove them and brush them daily with the same method.
What Precautions Should You Take to Protect Your Invisalign Material?
- Do not use toothpaste containing silica or baking soda on your aligners, as these abrasive ingredients can damage their surface.
- A hard or brittle toothbrush can scratch the surface of both the aligners and the case. Always use a soft-bristled brush.
- Always ensure the Invisalign case is completely dry before storing your aligners. Moisture can lead to bacteria buildup.
- Make sure your teeth and mouth are clean before putting the aligners back in to prevent bacteria and plaque buildup.
What Happens If You Don’t Clean Invisalign Trays?
Plaque and Bacteria Build-Up
When you eat and drink, food particles get trapped in the trays, causing plaque to form. Over time, this buildup can lead to bacteria growth. This, in turn, increases the risk of tooth decay and gum disease.
Discoloration
Without proper cleaning, Invisalign trays can become yellow or discolored. Once stained, it’s difficult to restore their original clear appearance.
Bad Breath
Bacteria and trapped food particles in unclean trays produce unpleasant odors. This can lead to bad breath.
By keeping your aligners clean, you reduce the risk of plaque buildup, maintain their clarity, and ensure your treatment progresses on schedule.
How to Get Rid of Mold in Your Invisalign Case
Mold in an Invisalign case develops when moisture is trapped without air drying. The black, brown, or pink spots are biofilm with bacteria and fungal growth. Throw out the case and replace it if mold is established; aggressive cleaning of a moldy case is not safe for daily aligner storage. For early-stage mold (a single spot or light film):
- Soak the case in 1 part white vinegar to 3 parts warm water for 30 minutes.
- Scrub every interior surface with a soft toothbrush dedicated to the case (not your tooth toothbrush).
- Rinse for at least 2 minutes under running warm water.
- Air dry the case open and upside down for at least 6 hours, ideally overnight.
- Inspect under bright light. If any discoloration remains, replace the case.
To prevent mold from coming back: always air dry the case open after washing, never store wet aligners in a closed case, and replace the case every 2 to 3 months. Patients in our Queens office who follow these steps almost never have mold issues.
How Often Should You Clean Invisalign Aligners?
You should clean your Invisalign aligners regularly. The best practice is to clean them every time you brush your teeth. This should be at least twice a day. Once in the morning and once before bed. Regular cleaning helps remove buildup from daily use.
If you eat or drink anything other than water while wearing your aligners, rinse them afterward. This will help prevent staining and bacteria from developing. Once a week, thoroughly clean your aligners to remove any buildup and prevent yellowing.
Signs That Indicate It’s Time to Replace the Invisalign Case
- If you notice any cracks, breaks, or chips in the case, it’s time for a replacement to ensure proper protection.
- A case that no longer fits properly or has become deformed won’t hold your aligners securely.
- Persistent stains or discoloration that can’t be cleaned off may harbor bacteria and should be replaced.
- If the case develops a bad smell despite regular cleaning, it’s a sign that bacteria buildup has occurred.
- If the case doesn’t close securely or the hinges are broken, it can no longer safely protect your aligners.
If you are still waiting for your first set of trays, your Invisalign trays typically arrive about 2 weeks after your scan, and your provider will give you the original case at the fitting appointment. Save it as a backup. After 2 to 3 months of daily use, request a fresh case at your check-in.
