Key Takeaway
Keeping your Invisalign aligners clean is simple. Rinse them with lukewarm water, brush gently with mild soap, soak them daily, and avoid anything that could scratch or stain the plastic. A few extra minutes each day will keep your aligners clear and odor-free.
Step-By-Step Guide to Clean Aligners
Follow these steps to keep your aligners clean, clear, and free from buildup.
- Rinse with lukewarm water every time you remove trays: Warm water helps loosen plaque and rinse away saliva. Avoid cold water, which does not clean effectively, and never use hot water, it can warp your trays.
- Brush gently with a soft toothbrush and liquid soap: Use a soft-bristled toothbrush and mild, clear, unscented antibacterial soap. Avoid abrasive toothpaste, which can scratch the plastic and trap plaque. Do not use scented soaps or strong cleaning products that are not made for dental appliances. Rinse the aligners very well before putting them back in your mouth.
- Soak aligners once daily: Use Invisalign cleaning crystals, a retainer cleaner, or an effervescent tablet designed for plastic trays. Refer to the directions on the packaging for soak time. Rinse well with lukewarm water before putting them back in.
- Try a vinegar or baking soda solution for deeper cleaning: Mix one part white vinegar with three parts water, or try a mix of baking soda and water. These natural antiseptics break down stubborn plaque and odor. Rinse thoroughly to remove all residue.
- Keep the case clean and dry: Wash the storage case daily with warm water and soap. Let it dry fully to prevent bacterial growth.
What to Avoid When Cleaning Trays
Avoid these common mistakes that can damage your trays.
- Toothpaste and mouthwash: Most toothpaste is too abrasive. Mouthwash often contains alcohol or dyes that damage plastic.
- Colored or scented soaps: These can stain trays or leave an unpleasant taste.
- Hot water or boiling: This warps trays and ruins the fit.
- Leaving trays in napkins or on tables: Easy to lose, easy to contaminate. Always use the case.
Pro Tips for Clean Aligners and Better Oral Hygiene
These small habits can make a big difference in keeping your treatment on track and your smile healthy.
- Brush and floss before putting your trays back in: This removes food particles and plaque, helping keep your aligners clean and your teeth protected.
- Avoid coffee, tea, or soda with trays in: These drinks stain and create sugar buildup. Remove trays before drinking. If you do drink anything other than water with your aligners in, give them a quick rinse after finishing the drink.
- Stay consistent: Add aligner cleaning to your oral hygiene routine. Nightly cleaning is the best time to clear away built-up food and plaque.
- Use safe cleaning agents only: Stick to approved products like retainer cleaner, Invisalign cleaning solution, or homemade baking soda mixes.

FAQs About Invisalign Cleaning
Can you use denture cleaner to clean Invisalign?
Yes, but only if the denture cleaner is labeled safe for clear plastic aligners. Some formulas may be too harsh and cause damage over time.
How often should you clean Invisalign?
Clean your trays every time you take them out and soak them at least once daily to prevent buildup of bacteria and plaque.
Can you brush Invisalign with toothpaste?
No, toothpaste is abrasive and can scratch the plastic, making it easier for bacteria and plaque to stick.
Why does my Invisalign get so dirty?
Aligners collect food particles, plaque, and bacteria throughout the day. Not brushing before putting them back in, drinking sugary beverages while wearing them, and not cleaning your trays regularly can cause them to get dirty quickly.
