Keeping your Invisalign® aligners clean is one of the most important parts of successful treatment. Daily cleaning removes plaque and bacteria, helps prevent odors and staining, and keeps your aligners fitting properly. In this guide, you’ll learn how to clean Invisalign® aligners correctly, which products are safe to use, how often to deep clean them, and the best habits for keeping them clear throughout treatment.
Why Invisalign® Aligner Care Matters
Proper Invisalign® care does more than keep your aligners looking clean. A consistent cleaning routine helps prevent bacteria buildup, preserves the trays’ transparency, and ensures they continue fitting correctly throughout treatment.
Improves Treatment Results
Properly looked after Invisalign® aligners let your treatment progress as planned by your orthodontist. Clean and damage-free aligners fit precisely so your teeth can move into the desired position. Poorly maintained aligners or excessive plaque buildup can hinder this progress and may extend the treatment time or be uncomfortable.
Prevents Odor and Bacterial Buildup
Invisalign® aligners are worn up to 22 hours a day, creating an environment where bacteria can grow if not cleaned regularly. Plaque and bacteria buildup can cause odor and bad breath, affecting your confidence and oral health. Regular cleaning routines reduce the risk of bacterial accumulation and keep you feeling fresh and clean every time you wear your aligners.
Maintains Aligners Transparency
One of the main benefits of Invisalign® aligners is their near-invisible appearance. You can correct your smile without the visible look of traditional braces—a key advantage in the ongoing Invisalign® vs braces comparison.. But without regular cleaning, the aligners can become discolored, reducing their transparency and making them more visible on your teeth. Committing to daily care can keep your aligners clear and will help them stay as discreet as possible during your treatment.
Daily Cleaning Routine for Invisalign Aligners
You need to follow a daily cleaning routine to keep your aligners clear and bacteria-free. If you follow a few simple habits, you will keep your Invisalign® aligners fresh, clean, and effective throughout your treatment.
Rinse Upon Removal
When you remove your aligners, take a quick rinse under lukewarm water. This will wash away the saliva and bacteria that have accumulated in the aligners while they are in your mouth, reducing odor and buildup. A quick rinse also makes it easier to clean them more thoroughly later in the day.
Use Gentle Brushing Techniques
Daily brushing is important to keep your aligners clean, but use a soft-bristled toothbrush and clear, mild soap instead of toothpaste. Toothpaste can scratch the surface of the aligners and cause cloudiness and visible wear. Gently brush both the inner and outer surfaces of each aligner to remove any bacteria or food particles, then rinse well before reinserting.
Avoid Hot Water
Always use cool or lukewarm water when cleaning your aligners. Hot water can distort the plastic and affect how the trays fit. If you’d like more tips on preventing accidental damage, read our guide on preventing damage to Invisalign® braces.
Dos and Don’ts of Invisalign® Aligner Care
For best results, follow these essential dos and don’ts to keep your Invisalign® aligners in top shape and make sure your treatment stays on track.
Dos:
- Clean Aligners Every Morning and Night: Make it a habit to clean your aligners twice daily — once in the morning and once before bed. Regular cleaning prevents bacteria buildup, keeps odors at bay, and helps maintain the aligners’ clarity.
Don’ts:
- Don’t Use Harsh Cleaners: Steer clear of abrasive or chemically-laden products like bleach, scented soaps, colored soaps, or toothpaste, as these can damage the aligners’ material or leave behind harmful residues. Instead, opt for mild soap or Invisalign®-recommended cleaning solutions to keep your aligners fresh and safe for use.
Tips to Deep Clean Invisalign® Aligners
Along with daily cleaning, deep cleaning helps keep your Invisalign® aligners sparkling. A few extra steps a week will keep them clear, prevent discoloration, and keep them as fresh as possible.
Soak Aligners Weekly
Use Invisalign® Cleaning Crystals or a similar aligner-cleaning product once a week to dissolve any stubborn stains and buildup that daily brushing might have missed. This quick weekly soak will keep your aligners clear and odor-free, allowing you to have a more discreet appearance and a comfortable fit.
Try a White Vinegar Solution
For a simple at-home deep cleaning, soak your aligners in a solution of one part white vinegar to three parts water for 15–20 minutes. This natural method will disinfect and deodorize your aligners without harsh chemicals. Be sure to rinse thoroughly with cool water afterward to remove any remaining taste or smell.
Brush After Meals
To prevent transferring food or bacteria to your clear aligners, get into the habit of brushing your teeth after every meal or snack. This will reduce the risk of odor, stains and decay by keeping your mouth clean before you put the aligners back in.
How to Stop Invisalign® Trays from Staining
Invisalign® aligners are supposed to be clear, but bad habits can stain them. Follow these tips to keep your aligners clear and invisible during your orthodontic treatment.
Limit Staining Drinks
Try to avoid drinks that stain like coffee, tea, red wine and sodas. Drinking these with your aligners in will stain them and make them more visible. If you drink, remove your aligners first and rinse your mouth before putting them back in.
Rinse Aligners
Every time you take out your aligners, give them a quick rinse under cool water. Rinsing removes saliva and bacteria that can cause buildup and staining. This simple step keeps your aligners cleaner and reduces the chance of staining over time.
Use Mouthwash without Alcohol
If you use mouthwash, use an alcohol-free one. Alcohol can damage the plastic of the aligners and cause staining, affecting their clarity and durability. An alcohol-free mouthwash will keep your aligners and teeth fresh without compromising the aligners’ appearance.

Keep Your Aligners Clean Between Uses
After cleaning your aligners, place them in a clean protective case until you’re ready to wear them again. Proper storage helps keep them clean and reduces unnecessary exposure to bacteria and dust.
