If you’ve chosen Invisalign® for your smile transformation, chances are you love that your aligners are clear, removable, and much less noticeable than traditional braces. But there’s one small catch: clear aligners need to stay clean to stay clear.
Your aligners spend most of the day against your teeth, so plaque, bacteria, food particles, and whatever you had for lunch can quickly find their way onto your trays. A good cleaning routine helps keep your aligners fresh, comfortable, and looking as discreet as they’re supposed to.
But with so many Invisalign cleaner options—from Invisalign™ Cleaning Crystals and Retainer Brite® to M3 Naturals, Polident tablets, ultrasonic cleaners, and mild soap—which one is actually the best?
Let’s compare the most popular options and help you find the right fit for your smile!
Quick Answer: What Is the Best Invisalign Cleaner?
For most Invisalign patients, the best cleaner is the one you’ll use consistently.
Mild, non-abrasive soap and a soft toothbrush work well for everyday cleaning, while Invisalign Cleaning Crystals, Retainer Brite, Polident, or M3 Naturals tablets can provide a deeper clean. An ultrasonic cleaner for Invisalign is another option if you prefer a more hands-off routine. Whatever you choose, avoid hot water, abrasive cleaners, and aggressive scrubbing that can damage or warp your aligners.
1. Invisalign Cleaning Crystals
If you’re looking for the best cleaner for Invisalign and want something made specifically for clear aligners, Invisalign Cleaning Crystals are an easy place to start.
The crystals dissolve in warm water, allowing your aligners to soak for about 15 minutes. They’re designed to help keep Invisalign aligners and retainers clean and fresh.
Our verdict: ⭐⭐⭐⭐⭐
A great choice if you want a simple, Invisalign-specific deep-cleaning solution.
2. Retainer Brite
Retainer Brite is a popular option for cleaning removable orthodontic appliances. The tablet dissolves in water to create a soaking solution that helps loosen buildup and freshen your appliance.
It’s especially convenient if you like the idea of dropping a tablet into a cup and letting it do the work. Just make sure the product you use is appropriate for clear aligners and follow the directions.
Our verdict: ⭐⭐⭐⭐
A convenient choice for patients who prefer tablets over crystals.
3. M3 Naturals Retainer Cleaner
M3 Naturals makes cleaning tablets marketed for retainers, aligners, Invisalign, and other removable dental appliances. The tablets dissolve in warm water before the appliance is soaked and thoroughly rinsed.
One important thing to note: the formula contains persulfates, so check the product label carefully if you have known sensitivities.
Our verdict: ⭐⭐⭐⭐
A convenient, budget-friendly tablet option, but make sure it’s appropriate for your specific appliance.
4. Polident Retainer Tablets
Polident offers cleaning products designed for removable appliances, including certain aligners and retainers. Its guidance recommends using a soft-bristled toothbrush for daily cleaning and following the directions for the specific Polident product you choose.
One important detail: don’t grab just any denture cleaner and assume it’s Invisalign-safe. Look at the label and choose a product specifically intended for aligners or removable dental appliances.
Our verdict: ⭐⭐⭐⭐
Easy to find and convenient, as long as you select the right formula for your aligners.
5. Ultrasonic Cleaner for Invisalign
An ultrasonic cleaner uses high-frequency sound waves to agitate water around your aligners and help loosen debris from hard-to-reach areas.
It can be a nice addition to your routine, especially if you’re someone who loves a gadget that makes everyday life easier.
It can also come in handy after Invisalign treatment when you’re cleaning your retainers.
Our verdict: ⭐⭐⭐⭐
A nice option for patients who love a little technology in their cleaning routine.
6. Mild Soap: The Underrated MVP
Sometimes the best Invisalign cleaner is already sitting at home.
A soft toothbrush and a small amount of mild, non-abrasive soap can provide an effective daily cleaning routine. The key word is mild—avoid anything abrasive, heavily colored, or harsh.
For daily care:
- Rinse your aligners with cool or lukewarm water.
- Gently brush the inside and outside with a soft toothbrush.
- Rinse thoroughly.
- Store your aligners in their case when you aren’t wearing them.
Simple? Yes. Effective? Absolutely.
What NOT to Use on Invisalign
This is the most important part of caring for your Invisalign trays!
Avoid:
- Hot or boiling water — heat can warp your aligners and affect their fit.
- Abrasive cleaners — aggressive products or scrubbing can scratch clear plastic.
- Hard-bristled toothbrushes — soft bristles are gentler on your trays.
- Household cleaners — stick with products intended for removable dental appliances.
And remember: never put your aligners back in without thoroughly rinsing them after using a soaking solution.

Frequently Asked Questions About Cleaning Invisalign
How often should I clean my Invisalign aligners?
Dr. Albert says: “I recommend cleaning your aligners every day, ideally when you brush your teeth. You should also rinse them with lukewarm water whenever you take them out. Regular cleaning helps prevent plaque and buildup from accumulating on the trays and keeps them looking and feeling fresh.”
Are Invisalign cleaning tablets safe to use every day?
Dr. Albert says: “That depends on the specific product. Some Invisalign cleaning tablets are designed for daily use, while others have different recommendations. I always encourage my patients to follow the product instructions and ask our office if they’re unsure whether a particular cleaner is appropriate for their aligners.”
Do I need an ultrasonic cleaner to keep my Invisalign clean?
Dr. Albert says: “No. An ultrasonic cleaner can be a convenient addition to your routine, but it isn’t necessary for successful Invisalign treatment. A soft toothbrush, mild soap, regular rinsing, and an occasional aligner-safe cleaning solution are enough for most of my patients. If you prefer the convenience of an ultrasonic cleaner, we can help you decide whether it makes sense for your routine.”
Why are my Invisalign aligners turning cloudy or yellow?
Dr. Albert says: “Cloudiness or discoloration is usually related to plaque, bacteria, food or drink residue, or mineral buildup on the trays. I recommend removing your aligners when you eat or drink anything other than water and cleaning them regularly. If an aligner becomes significantly discolored or damaged, let us know so we can determine whether it needs to be replaced.”
Can I eat or drink while wearing Invisalign?
Dr. Albert says: “I recommend removing your Invisalign aligners before eating or drinking anything other than water. Food and beverages can become trapped against your teeth and can stain the aligners. Removing your trays also gives you the opportunity to brush and floss before putting them back in, which is an important part of keeping your teeth healthy during treatment.”
Is Invisalign harder to keep clean than braces?
Dr. Albert says: “Invisalign requires a little different kind of maintenance, but many patients actually appreciate how easy it is to keep their teeth clean because the aligners are removable. You can brush and floss normally without working around brackets and wires. The key is being disciplined about wearing, removing, cleaning, and storing your aligners as instructed.”
