How to Clean Invisalign the Right Way (Without Damaging It)
To clean Invisalign, rinse the aligners whenever they're out of your mouth, gently brush them once or twice a day with a soft toothbrush and a little clear, mild soap in lukewarm water, then rinse and reinsert — and avoid heat, coloured or scented soaps, toothpaste, and anything abrasive. Clean trays stay clear, smell fresh, and don't trap the bacteria that cause staining and odour.
To clean Invisalign safely: rinse trays in lukewarm water every time they come out, brush them gently with a soft brush and clear mild soap once or twice a day, and skip hot water, toothpaste, and harsh chemicals, which can warp, scratch, or cloud the plastic.
This guide walks through a simple daily routine, what's safe versus what quietly damages your aligners, and how to keep them clean while you track your wear time. It applies to Invisalign and other clear aligners alike. For the bigger picture, see our clear aligner tracking guide.
Why cleaning Invisalign matters
Your aligners sit against your teeth for around 22 hours a day, which is plenty of time for saliva, plaque, and tiny food particles to build up on the plastic. Left alone, that film causes three problems:
- Cloudiness. Invisalign is meant to be nearly invisible. A layer of dried saliva and plaque turns clear trays foggy and dull, so they show more when you smile.
- Odour. Bacteria trapped between the tray and your teeth produce a smell you'll notice the moment you take the aligners out — and sometimes on your breath.
- Staining. Coffee, tea, red wine, and coloured foods can tint a poorly cleaned tray. Once the surface is scratched or etched, stains cling far more easily.
Keeping trays clean isn't just cosmetic. A film of bacteria against your teeth for most of the day isn't great for your gums either, so a quick cleaning habit protects both your aligners and your mouth.
A simple daily Invisalign cleaning routine
You don't need anything fancy — just consistency. Here's a routine that takes under two minutes:
- Rinse every time they come out. Whenever you remove your aligners to eat or drink, rinse them under lukewarm (never hot) water right away. This washes off saliva before it dries and hardens.
- Rinse your mouth too. Give your teeth a quick rinse before putting the trays back in, so you're not sealing food particles against them.
- Brush them gently, once or twice a day. Use a separate soft-bristled toothbrush and a small amount of clear, mild soap. Brush the inside and outside of each tray in light circles — no scrubbing.
- Rinse thoroughly. Rinse all the soap off under lukewarm water so nothing lingers when you reinsert them.
- Reinsert or store dry. Put them straight back in, or if they'll be out for a while, store them in their case — clean and dry, not wrapped in a napkin where they get lost or crushed.
Morning and night pairs naturally with brushing your teeth, so it's easy to remember. If you only deep-clean once a day, make it the evening, when the most has built up.
Safe vs. unsafe ways to clean Invisalign
The plastic Invisalign is made from is softer and more delicate than your teeth. Many everyday cleaning habits that seem harmless will quietly scratch, warp, or cloud it. Here's the split:
Safe to use:
- Lukewarm or cool water — for rinsing throughout the day.
- A soft-bristled toothbrush — kept separate from the one you use on your teeth.
- Clear, mild, unscented soap — a small amount goes a long way.
- Aligner cleaning crystals or tablets — products in this category are made for soaking trays; follow the label and rinse well afterward.
Not safe — avoid these:
- Hot or boiling water. Heat warps the plastic. A warped tray no longer fits your teeth correctly, which can set your treatment back.
- Toothpaste and other abrasives. Toothpaste is mildly gritty and scratches the surface; those micro-scratches trap stains and make trays look cloudy.
- Coloured or scented soaps and hand washes. Dyes can tint the plastic and fragrances can leave a taste or residue against your teeth.
- Harsh chemicals. Bleach, hydrogen peroxide, denture products not meant for aligners, and mouthwash with strong dyes can discolour or degrade the trays.
When in doubt, gentler is better. Lukewarm water and a soft brush will handle the vast majority of daily cleaning.
A weekly deep clean
Once a week, give your aligners a longer soak to lift the buildup that daily brushing misses. Fill a small cup with lukewarm water and add an aligner cleaning tablet or a measure of cleaning crystals — the product category made specifically for this. Drop the trays in, soak for the time the label recommends, then brush gently and rinse thoroughly before wearing them again.
A soak reaches the grooves and edges a brush can skip, and it's the easiest way to keep long-term cloudiness at bay. Never soak in hot water or in anything not intended for aligners, and always rinse well so no cleaning solution stays on the plastic when it goes back in your mouth.
Keeping trays clean while you track your wear time
Cleaning and tracking go hand in hand, because both happen at the same moments — every time your aligners come out and go back in. A tracker app like TrayJourney turns those moments into a habit loop: you tap out when you remove the trays (a natural cue to rinse them), and tap back in when you reinsert (after a quick clean). The app tallies your daily wear time against your goal so your treatment stays on pace, while the rinse-and-brush routine keeps the trays clear.
Pairing the two means your aligners stay both clean and on schedule without you having to think about it. For more on the wear-time side, see our Invisalign tracker guide. And because these habits are identical across brands, our generic how to clean clear aligners walkthrough covers the same steps for any tray.
Frequently asked questions
Can I use toothpaste on Invisalign?
No. Toothpaste is mildly abrasive and leaves micro-scratches on the soft aligner plastic. Those scratches make trays look cloudy and trap stains more easily. Use a soft brush with a little clear, mild soap and lukewarm water instead.
Can I use hot water to clean Invisalign?
No. Hot or boiling water warps the plastic, and a warped tray no longer fits your teeth properly — which can disrupt your treatment. Always rinse and soak in lukewarm or cool water.
How often should I clean Invisalign?
Rinse your aligners every time they come out, and give them a gentle brush once or twice a day — ideally morning and night when you brush your teeth. A longer soak once a week lifts any buildup the daily routine misses.
Can I use mouthwash or bleach to clean my trays?
It's best not to. Mouthwash with strong dyes can tint the plastic, and bleach or other harsh chemicals can degrade and discolour it. Stick to clear mild soap or a product from the aligner cleaning crystals and tablets category, and rinse thoroughly afterward.
