How to Clean Invisalign Trays With Hydrogen Peroxide?

Did you know Invisalign trays are meant to last for 12 months straight? However, it is possible only if you clean them properly.

Without proper maintenance, the material will break down and become more harmful than helpful. As for the term cleaning, it doesn’t just mean washing all the stuff off them. Instead, it needs special care to remove bacteria and stains.

f you are using Invisalign, you will want to know how to clean them. You may even wonder if the trays can ever be cleaned. z

Well, many things can go wrong with Invisalign if you do not know how to clean them properly.

Today we’ll talk about the best way to clean your Invisalign trays and why it is important.

We will cover everything from why you need to clean your trays with hydrogen peroxide to how and what you should do with them with all the safety precautions.

Why Do You Need to Clean Invisalign Trays?

Every daily use item requires special care and cleaning procedures. Invisalign tray also falls under the category. Not cleaning the trays can make them look stained, corroded, or scratched. As a result, these won’t remain invisible as they were before. Some primary reasons for cleaning the Invisalign trays are as follows:

To Get Rid of Bacteria

Microbes are everywhere in our surroundings. According to the NIH, even our mouths aren’t safe from exposure.

The human mouth has 700 different species of bacteria. In solitary numerical value, the number jumps up to 20 million bacteria. The saliva in our mouth cavity keeps the number in a harmless range for the human body.

However, Invisalign trays act as a growth culture for these tiny organisms. Without proper sanitation strategy, the growth rate of these bacteria upsurges.

An increased colony population of microbes can result in several acute and chronic infections. To get rid of these, you need a proper disinfecting methodology. That is where several disinfectants come in. They inhibit bacterial, fungal, and viral growth, saving you from unintentional hazards.

To Make Them Appear Shiny and Appealing

A Chinese proverb says, “A smile with a thousand ounces of gold.” What good are your thousand ounces of gold if they are full of stains, streaks, and corrosion?

That is the exact reason why you should clear your alignment Invisalign trays. Inside your mouth and as a cover on your teeth, these become visible whenever you speak or smile.

However, these stay appealing only if you try to keep them. Cold beverages or poor oral hygiene can cause discoloration or add stains.

The best way to make them everlasting is through cleaning after proper intervals. Cleansing your Invisalign can be easier with strong stain removals like Hydrogen peroxide.

To Prolong Their Life

Maintaining any equipment is the best way to enhance product life. Just like that, Invisalign trays also require constant cleaning for longer life.

Food products and other beverages can cause stain formation on the trays. Therefore, you must maintain proper oral hygiene at all times.

As these trays are removable, you can easily get them out and use proper cleaning measures to eliminate any stain-causing elements or food compounds.

Cleaning these alignment trays after adequate intervals help minimize stain induction. In addition, using strong cleaning agents can help you clear any discoloration agents.

That is why remediation of Invisalign trays keeps them invisible for longer periods and prolongs their life.

How to Clean Invisalign Trays With Hydrogen Peroxide

Now that you know cleaning Invisalign trays must be cleaned daily, you may ask what the best method is.

Experts suggest using a strong disinfectant and stain-removing agent. There is no better option in the market other than hydrogen peroxide.

Hydrogen peroxide has great oxidative properties that make it an active stain removal. Plus, it helps to kill and inhibit microbial growth.

#1 Using Hydrogen Peroxide to Disinfect Invisalign Trays

Hydrogen peroxide with the formula of H2O2 is an excellent disinfectant. It has been used for centuries to disinfect water and other liquids, but it’s also been shown to disinfect Invisalign trays effectively.

In a study published in the Journal of Orthodontics, researchers found that using hydrogen peroxide to sanitize the trays resulted in significantly lower levels of bacteria. Instead, the trays that weren’t exposed to hydrogen peroxide had more microbial growth.

These findings aren’t conclusive proof that hydrogen peroxide is an effective alternative to bleach or other common disinfectants. However, they show that hydrogen peroxide could replace some of today’s more harmful disinfectants.

What You Need

How to Use

First, gather all your supplies. It is better to soak your Invisalign trays in a water container first. Using only hydrogen peroxide can be damaging for your Invisalign trays. The reason is its abrasive nature.

Therefore, we use water to make it less corrosive for the trays. The first step is to take two equal concentrations of water and hydrogen peroxide. Now mix them both in a container for a liquid composition.

Next, soak the Invisalign trays inside the mixture for 20 to 25 minutes. After the time limit, get them out and rinse thoroughly under running water.

Finally, air dry the alignment trays, and voila! They are ready to use again, as good as new.

#2 Using Hydrogen Peroxide to Shine Invisalign Trays

Hydrogen peroxide is an incredibly effective natural abrasive. It can clean and polish metal, glass, and other surfaces.

It is one of the most common ingredients in home-cleaning products. You may have even seen it around your house before.

It’s that liquid that you squirt on your counters and sinks when you’re doing dishes or cleaning a toilet bowl. The reason is its naturally unstable state that causes abrupt oxygen eruption.

Consistent oxidation can help to remove any stain or shine on the surface of trays. It removes them from the root by targeting the chemical bonding and eliminates the stains entirely.

What You Need

How to Use

Using hydrogen peroxide to shine your old Invisalign trays isn’t very complex. The process is somewhat similar to the cleaning process. First, gather all the supplies and try to perform the task in a shady environment as sunlight decomposes hydrogen peroxide.

Mix equal parts of water and hydrogen peroxide to get its abrasive nature down. Make sure that the water is neither cold nor hot. Instead, it must have an adequately warm temperature.

Mix well until the mixture is homogenous. Now add your trays and soak them in for 20 to 30 minutes. Lastly, take it out using gloves and rinse it using water. Put them in again once they are completely dry.

How Can I Make My Invisalign Trays Clear Again?

If you want to make your Invisalign trays clear again, there are a few options. The first is using hydrogen peroxide.

It is a great way to unclog any buildup in the trays that might be the reason for the stain or discoloration. It also has the benefit of being inexpensive and easy to find at most pharmacies or grocery stores.

Another way is to use a mixture of hydrogen peroxide, baking soda, and water. It can help you create a strong abrasive mixture that is powerful enough to make them clear again.

What Can I Soak My Invisalign Trays in to Clean Them?

The first option is to soak your Invisalign trays in hydrogen peroxide and water. It will help remove any build-up on the tray, as well as help keep your trays clean from microbes.

You’ll want to leave them in the solution for at least 30 minutes, but you could leave them overnight if you have time.

If you don’t have hydrogen peroxide on hand, you can try soaking your trays in a mixture of lukewarm water and vinegar.

Just mix half a cup of vinegar with a cup of lukewarm water until it reaches a paste. Then place your trays in the solution for 15 minutes, and rinse thoroughly with warm water.

Can You Use Hydrogen Peroxide to Safely Clean Invisalign Trays?

Remember, Invisalign trays are made from a material similar to plastic. Like any plastic, it’s susceptible to breaking down when exposed to high temperatures or strong chemicals.

That’s why you should never use hydrogen peroxide on your Invisalign trays directly.

You must be sure that no more than 3% concentration is being used at any time. To do so safely, mix the hydrogen peroxide concentration with water before applying it to your tray.

Also, be sure not to leave any containers of concentrated hydrogen peroxide open during this process, as they’re likely to decompose.

How Often Should You Clean Invisalign Trays?

There are a few factors to consider when deciding the frequency of cleaning your Invisalign trays.

First, you need to consider how many days a week you wear your trays. If you wear them for eight hours a day, you can expect to clean them daily after use.

If you wear your trays for five hours a day, you should clean them at least twice every four days.

Moreover, if they’ve been on for less than two years, then it’s recommended that you do so at least once per day.

Do You Have to Clean Invisalign Every Time You Take Them Out?

The frequency of cleaning your Invisalign trays depends on your case. You should clean your Invisalign trays every week or as needed.

If you have been cleaning your trays every week, you can continue to do so without making any changes to the frequency.

However, if you notice that the trays are getting dirty or smudged, it’s worth it to go ahead and clean them every time you take them out.

Why Hydrogen Peroxide is Best for Cleaning Invisalign Trays?

Hydrogen peroxide is the most effective way to clean your Invisalign trays. As a disinfectant, hydrogen peroxide is capable of killing 99% of all germs on contact.

Hydrogen peroxide has no adverse effects on your teeth or gums because it does not contain any fluoride or salts. Besides that, the compound has an active

Best Antibacterial Properties

Hydrogen peroxide has a high pH level that is more acidic than other common household cleaners. When mixed with water, it forms a strong antiseptic solution.

It means that it can kill bacteria, viruses, and fungi that are present in your mouth. As a disinfectant, it can also prevent the growth of new germs in your mouth by destroying the existing ones.

It also kills Streptococcus mutans, an especially hard-to-kill form of bacteria that causes cavities. By killing these germs, hydrogen peroxide helps prevent cavities and other dental problems.

Harmless Byproducts

Hydrogen peroxide also has harmless byproducts when used as a disinfectant, which means it won’t damage any materials (like your metal brackets).

It makes it easy to use on everything from plastic brackets to toothbrushes. On the decomposition, only water and oxygen erupt as by-products.

These are completely safe for the human body. So, we can say their exposure to the mouth won’t be toxic for human health.

Reasonably Straightforward to Get and Use

Hydrogen peroxide is an easily accessible liquid you may have seen around your house. It is an over-the-counter disinfectant available at most clinics and medical stores.

Hydrogen peroxide is an active part of most of our household supplies. It is present in the mouthwash to some of our detergents.

The easy accessibility, usage, and handling make it the ideal choice for cleaning the Invisalign trays.

What Happens If You Don’t Clean Invisalign Trays?

Invisalign trays are designed to be removable, making them easy to clean. The plastic polymer inside them doesn’t allow water or saliva to get through.

That is why the only way to remove debris is by cleaning them. Untreated trays can lead to bad breath, tooth discoloration, and the possibility of infection and inflammation. We’ll look at some disadvantages of leaving your Invisalign trays untreated.

Bad Breath

Throughout our day, we eat several different types of foods. These meals sometimes get caught up in the tray. Getting them out isn’t possible without cleansing.

Therefore, if they keep staying there for a more extended period, they can cause bad breath. Think of it as a spoiled food ground.

Leaving them there for weeks or days can cause their decomposition by bacteria and cause inflammation, sore gums, and bad breath.

Even rinsing isn’t enough for you to get rid of bad breath. You need constant cleaning to eliminate every grain of food in the trays.


Stains are also possible if you don’t clean your Invisalign trays regularly. The polymer that makes up the trays is made of different chemicals.

These diverse compounds can react with toothpaste or other substances in your mouth and create stains on your trays.

Stains can also lead to bad breath and an overall unappealing appearance. Plus, it takes the lifespan of the trays down to a great extent.

If you don’t want this problem, it’s best to rinse your trays before brushing your teeth with toothpaste or during a meal when you may spill something on them (or use mouthwash).


If your trays don’t receive the attention they need, they could become breeding grounds for bacteria that lead to infections in your mouth.

These infections can cause pain, discomfort, oral soreness, and swelling in the gums around your teeth.

You may even develop an abscess or boil on your gum line if left untreated for too long.

It is especially likely to happen if you sleep with them overnight or wear them all day long without cleaning them properly.

So, to prevent this from happening, try cleaning them daily after use. Plus, rinse them whenever you get them out of the mouth.

Disruption of Taste

Not cleaning your Invisalign trays could lead to the disruption of taste buds. In that case, food doesn’t taste good anymore, and the overall taste gets disrupted.

Debris inside your Invisalign trays can cause a significant change in your taste. You can get a sensational sour taste from the trays. Not only that, but they can alter your mouth taste and cause problems in everyday food taste sense.

It can have severe consequences if this happens while eating or drinking anything with a strong taste, like coffee. You may panic, and it gives a strong hallucinative vibe.

The Ideal Hydrogen Peroxide Concentration to Clean Invisalign Trays

Hydrogen peroxide is a commonly used disinfectant for oral health care. However, its pH is acidic in its concentrated form.

Therefore, the best way to use it is to use only 3% hydrogen peroxide, which isn’t much abrasive. Besides that, you can use it with water to create a diluted mixture of hydrogen peroxide that will also serve the purpose.

The 3% hydrogen peroxide is not as dangerous as the concentrated one. Therefore, it is easily available in most stores for public use.

Follow These Safety Precautions

Hydrogen peroxide is a common household cleaning product that has many uses. Cleaning Invisalign trays is one of them. However, it isn’t as simple as it seems.

Hydrogen peroxide poses several risks in its concentrated form. In addition, its diluted form also requires several safety precautions that the user must follow.

  • Always follow the instructions on the bottle of hydrogen peroxide. Do not put more than what is recommended.
  • It is better to rinse the trays thoroughly after the cleaning procedure. Without proper rinsing, the liquid may stay on the tray and cause sore gums or other toxicity symptoms that may result in an infection.
  • Hydrogen peroxide is very potent and can cause serious damage to your skin if it comes in contact with the eyes.

Therefore, Use rubber gloves when handling the hydrogen peroxide. You should also wear goggles or glasses while working with the solution so that you don’t get any in your eyes.

  • If your skin comes in contact with hydrogen peroxide and you feel irritation, try to use water for rinsing and look for medical assistance.
  • Do not add extra cleaning agents to enhance the effect of the mixture. The addition of components like bleach and vinegar can bring devastating outcomes for you.

The Bottom Line

To ensure the long-term health of your Invisalign trays, they must be kept clean. Experts recommend that you clean them each time after you take them out of your mouth.

Hydrogen peroxide is the recommended cleaning agent for Invisalign trays. Its common use in orthodontists’ and surgeons’ strategies has made it a public choice.

It is the way to ensure their safety while enjoying the benefits they get from their trays without side effects.

Best of all, you can buy it inexpensively by the bottle or in bulk from our firm. So, what are you waiting for? Order your set immediately and get rid of stained and dirty Invisalign trays.
