Hair clippers need cleaning. The cleaner they are, the better they perform. 

For blades to be dirt-free, they need an effective disinfectant. 3% hydrogen peroxide can do that.

In this article, I will guide you on how to clean your hair clippers with hydrogen peroxide and give you tips that could save your blades. 

With that said, take a look at the table of contents, and let’s begin.

 Power off
Disconnect your clippers from the power source and remove any attachments or blades on your clippers 

Then remove the top front cutting rail and top cutter blade.
Put on some gloves and mix a small solution of 25% hydrogen peroxide and 75% water into a flat bowl or cup. (A 1:3 ratio is best)
Using your cotton swab, or small hard bristle brush, scrub your hair clipper blades to remove hair and dirt. 

Try to get into the hidden parts of your blades by scrubbing in the direction of your blades.
When done, wash down your blades with some cold water and dry them thoroughly.
Re-attach your blades back onto your hair clipper making sure they are aligned.
Oil your hair clipper blades.

How clean your clippers are can make a difference in how safe your clients are as you work on their hair.

Your clippers work on a wide range of hair types and in the process, can easily hold blood and infections between the cutter which can be easily passed on.

I don’t think you’ll be doing your clients a benefit if you put them at risk. 

The steps I have laid out above are a quick run-through on how to clean hair clippers with hydrogen peroxide. Later on in this article, I go far more in-depth on this process. 

However,  while hydrogen peroxide can be effective at cleaning your blades, it does have some drawbacks, I talk about that next. 

Can You Clean Clippers With Hydrogen Peroxide

Can you clean hair clippers with hydrogen peroxide

Yes, hydrogen peroxide can clean hair clippers but you must use a sparing amount to make sure it doesn’t corrode your blades but still deep cleans them in the process. 

Hydrogen peroxide does have the potential to corrode stainless steel. This is the metal most commonly found on modern hair clippers.

Stainless steel is resistant to corrosion, stainless steel contains 12-30% chromium and it’s a passivity layer that acts as a shield against corrosion. this layer blocks oxygen from getting into the steel’s surface.

While this does protect your blades from corrosion, exposing your blades to heavy amounts of hydrogen peroxide for a long time will eventually corrode your clippers.

This is because hydrogen peroxide is an oxidizing agent and can weaken the passive chromium layer making your blades vulnerable to rust.

But this is in extreme cases, with the method I provide to you, hydrogen peroxide will only be in contact with your blades for a few minutes. Your blades naturally will be able to resist the effect of hydrogen peroxide.

 Hydrogen peroxide is great at cleaning. It is a fantastic disinfectant that kills bacteria and germs which build up in around your blades.


But you must realize, that hydrogen peroxide is not made for hair clipper blades so it has some adverse effects as I have just mentioned. 

Keep the hydrogen peroxide to 3% as the higher concentration you use, the more corrosive irritating the product become:

Step 2: Hydrogen peroxide

Put on some gloves.

Mix a solution of equal parts water and hydrogen peroxide in a small bowl or cup. 

Aim to keep it to a 1:3 ratio of hydrogen peroxide to water. You can use a higher concentration of hydrogen peroxide if necessary, but be aware that it can be harsh and may cause damage to your blades over time.

Step 3: Scrub

Dip a smooth brush or cloth into the solution and use it to scrub the blades and other surfaces of the clippers. Be sure to get into all the crevices and corners.

While you should work to get as much dirt and grime off both your blades, you don’t want to scrub too hard and remove the chromium layer. 

If you’re struggling, let your clippers sit in the water-peroxide solution for a minute or two and try again to remove the dirt.

Step 4: Dry

Rinse the clippers thoroughly with water to remove any residue. This will help prevent corrosion and ensure that the blades are clean and ready for use.

Then, you must Dry your clipper blades completely before reassembling them and using them again. 

This is important because moisture can also cause corrosion and may affect the performance of the clippers

Step 5: Further check

Before you put your clippers back together, you must make sure the internal components of your clippers are clean too. 

If the inside of your clippers looks like this:

They need to be thoroughly cleaned out. 

Use a toothpick or hard bristle brush to remove as much dirt and debris from within your clippers. 

You can also use an air can to get rid of very tricky bits of hair.

Allowing this grime to build up puts your hair clipper motor at risk and stops your clippers from working at their best. 

But do not put any hydrogen peroxide inside your clippers!

Use a dry tool to clean the internal parts of your clippers and if you have a blower use that to get rid of any hidden micro hairs. 

Step 7: Re-attach

Once both your blades and your clipper are clean, you can re-attach your blades back onto your clippers.

Put your clipper blades back onto the setter.

Then palace your front rail blade on top making sure the holes for both line screws line up

Now, individually put your screws back into the hole gap, and using your screwdriver, screw your blades back together but not fully as you have to make sure the alignment is correct.

Step 8: Align

Move the front cutting rail blade to make it parallel to the cutting blade

Make sure the top cutter is also as straight as possible.

When done, screw your blades firmly back together.

Step 9: Oil

Once your blades are put back together, use hair clipper oil. Apply oil to your blades in the areas shown below:

Once done turn your clippers on and work the oil into blades by opening and closing the lever for 20 seconds. 

Afterward, wipe away any excess oil.

With that, your clipper blades and hair clippers should now be clean and ready for use. 

Thai method cleaning when done can be very effective but it should be done sparingly I.e once a month to reduce the effect of hydrogen peroxide on your blades 

If this cannot be done and you need to clean your clippers more frequently, take a look at my guide on sterilizing hair clippers.
