4 ways to keep your aligners clean and happy

When it comes to cleaning your clear aligner you know you have to do it everyday. But what can you clean it in?Let us walk you through some steps on how to clean your aligners. 

Aligners have an unfortunate habit, just like we all do. Aligners have a tendency to attract grime and gunk which in turn can smell. And frankly, no one wants a smelly mouth. In your aligner box, we provide a set of instructions on how to properly clean your aligners (which needs to happen daily) but if you’ve lost the sheet or just can’t remember, don’t worry! We’ve got some cleaning options and tips for you. 

Let’s start: How to clean your aligner
Aligners are made of porous material, which means they absorb whatever you choose to clean them with. So it’s important to use cleaning products that are not only safe for your aligner but also your mouth. 

It’s important to be cautious of what you’re cleaning your aligner with, not everything that seems like a good cleaning solution actually is. For instance, mouthwash. Mouthwash may seem like a good solution to clean your aligner with but some of the ingredients in mouthwash can actually dry out your aligner and can damage them as well. 


So, what can you clean it with?

We have 4 fantastic options for you to choose from. 


  1. Vinegar and water 
  2. Baking soda and water
  3. Hydrogen peroxide and water 
  4. Retainer cleaner 

Vinegar cleaning solution for clear aligners

Vinegar and water
Vinegar is a natural disinfectant  and a good way to help keep your aligner bacteria-free. 

In a cup, mix 1 part vinegar to 3 parts warm (but not hot) water. Soak your aligner for at least 20 minutes, then rinse it off in cool water. 

Baking soda solution for cleaning clear aligners

Baking soda and water
Now baking soda is a good option for not only cleaning your retainer but if you notice your retainer is a little fragrant, baking soda will keep deodorize it as well. Because baking soda is a natural base, it neutralizes acidity and rebalances the mouth.

Mix one tablespoon (15 mls) with ½ a cup of water and then soak your aligners for 60 minutes. Rinse them off before putting them back on. 

Hydrogen Peroxide solution for cleaning clear aligners

Hydrogen Peroxide and water
Hydrogen peroxide is just one of those disinfectants found in almost every household, you know which bottle we’re talking about, the one with white cap and brown bottle? Yes that one. 

Mix equal parts hydrogen peroxide and water together in a glass and toss in your aligners for at least 20 minutes. You can easily pass the time by watching all those fizzy bubbles work their magic!

Denture cleaner solution for cleaning clear aligners

Retainer Cleaner and water
Now, we think this one is pretty self explanatory, all you have to do is drop a little pre-pressed tablet into a glass of water, let it fizzle away then drop in your aligners for 15-20 minutes. Rinse it off and then you’re good to go! 


We don’t use caps lightly over here so just know these are very important not to use to clean your aligners.

Never ever ever ever ever use

Bleach, rubbing alcohol or other harsh chemicals
We shouldn’t have to remind you that using harsh chemicals on something that goes in your mouth for 20 hours a day is NOT a good idea. 

Boiling water
Although boiling things in water is a good way to sterilize them, hot temperatures and aligners don’t mix. You can warp and ruin your aligner by boiling it which will prolong your treatment as you will have to get a replacement aligner.

Toothpaste is great for your teeth, not for your aligner. Depending on the brand toothpaste can be abrasive and scratch/dull your aligner which is no bueno. It’s always best to use our suggested cleaning solutions rather than your toothpaste. 


A clean aligner is a healthy aligner and healthy aligners make for straight healthy teeth.
