Invisalign clear aligners offer a discreet and removable alternative to traditional braces. While they are known for their convenience and comfort, maintaining your aligners’ cleanliness is an essential part of ensuring effective treatment and good oral health.
Many patients at The 32 Dental Solutions Dental Studio ask us, “How do you clean Invisalign aligners the right way?” In this blog, we’ll walk you through the best practices for cleaning your aligners, based on dental hygiene recommendations and practical tips.
Why Is It Important to Clean Your Invisalign Aligners?
Because Invisalign aligners are worn for 20–22 hours a day, they are exposed to:
- Saliva
- Food particles
- Bacteria
- Plaque
If aligners are not cleaned regularly, they can become discolored, develop unpleasant odors, and harbor bacteria that may lead to oral health problems such as tooth decay or gum inflammation. Cleaning your aligners daily helps maintain:
- Clear, stain-free trays
- Fresh breath
- A healthy oral environment
- Comfort during use
How Do You Clean Invisalign Aligners? A Step-by-Step Routine
Rinse After Every Removal
Each time you remove your aligners—for eating, drinking (anything besides water), or brushing—rinse them thoroughly with lukewarm water. This helps prevent plaque and saliva from drying on the surface.
- Avoid hot water, as it may warp the aligners and affect their fit.
Brush Gently with a Soft Toothbrush
Use a soft-bristled toothbrush and clear, unscented liquid soap to gently brush your aligners at least twice a day. Focus on both the inner and outer surfaces and avoid scrubbing too hard.
- Do not use toothpaste or colored soaps, as they may scratch or stain the plastic.
Soak in a Cleaning Solution
For a deeper clean, soak your aligners once daily using:
- Invisalign Cleaning Crystals, or
- Retainer/denture-cleaning tablets
Let the aligners sit in the solution for about 15–20 minutes, then rinse thoroughly before placing them back in your mouth. This step helps remove bacteria and mineral buildup.
Clean Your Teeth Before Reinserting Aligners
It’s important to brush and floss before putting your aligners back in. This reduces the risk of trapping food particles and bacteria, which can contribute to tooth decay and bad breath.
Cleaning Solutions: What’s Safe and What to Avoid
Safe Options:
- Mild clear soap
- Invisalign Cleaning Crystals
- Retainer/denture cleaning tablets
- Diluted white vinegar (1 part vinegar, 3 parts water) — occasional use
- Diluted 3% hydrogen peroxide — occasional use only
What to Avoid:
- Toothpaste: Often abrasive, leading to scratches
- Colored mouthwash: Can discolor the trays
- Hot water: May deform the aligners
- Harsh chemicals: Not intended for oral appliances
If unsure about any cleaning product, consult your dental care provider before use.
Can You Eat or Drink with Aligners In?
No. It’s recommended to remove aligners when eating or drinking anything other than water. This prevents:
- Staining or discoloration
- Warping from hot liquids
- Buildup of food particles
- Increased risk of decay due to trapped sugars or acids
Always store aligners in a clean case when not in use.
How Often Should You Clean Your Aligners?
- Rinse: After each removal
- Brush with soap and water: Twice daily
- Soak for deep clean: Once daily or every other day
Consistency helps keep aligners looking clear and reduces the risk of oral health issues during treatment.
Why Aligner Hygiene Matters During Orthodontic Treatment
Aligner cleanliness isn’t just about aesthetics. Research shows that poor hygiene with removable orthodontic appliances can contribute to increased plaque accumulation and potential enamel demineralization. Regular cleaning practices not only support treatment success but also protect your teeth and gums throughout the process.

FAQs
Can I use dish soap to clean my Invisalign aligners?
Yes, mild, clear liquid dish soap without dyes or fragrances can be safely used to clean your aligners. Use it with a soft toothbrush and rinse thoroughly afterward. Always avoid heavily scented or colored varieties.
Is it safe to use mouthwash to soak Invisalign trays?
No. Most mouthwashes contain dyes and alcohol, which can stain or degrade the aligner material. Instead, use Invisalign Cleaning Crystals or clear retainer-soaking solutions approved for oral appliances.
How do I remove cloudy buildup from my aligners?
Soaking your aligners in a mixture of equal parts water and white vinegar for 15–20 minutes can help dissolve calcium or mineral deposits. Brush gently afterward and rinse thoroughly before reinserting.
Are ultrasonic cleaners safe for Invisalign aligners?
Yes, ultrasonic cleaning devices designed for retainers and aligners can be effective. Use them as directed, ideally with a cleaning solution approved for dental appliances. Consult your dental provider before purchasing.
What happens if I skip cleaning my aligners for a day?
While a single missed cleaning may not derail your treatment, it can lead to temporary plaque buildup or odor. If this happens, soak the aligners immediately and resume your regular cleaning routine. Consistency is essential to prevent long-term issues.
Can I brush my aligners while brushing my teeth?
It’s better to use a separate toothbrush dedicated to cleaning aligners. Toothpaste residue and bacteria from your regular brush can damage the aligners or leave residue behind.
What should I do if my aligners start to smell?
A foul odor can indicate a buildup of bacteria. Try a deep clean with Invisalign Cleaning Crystals or a retainer-cleaning tablet. Make sure you’re brushing and rinsing the aligners regularly and cleaning your teeth before wearing them.
How long can I leave Invisalign trays out while cleaning?
Try to keep them out for no more than 15–30 minutes. Invisalign trays should be worn for 20–22 hours a day to be effective.
