I remember that I have written an article about the best microphone for ASMR, and just thinking about how audio people record the ASMR noise, makes me want to clean my microphone.

I mean, ASMR noses should be recorded really close to the microphone, and that’s why you are touching or spluttering the microphone all the time. And most of the time we totally forget that we have to clean the things around us, and that happens with the microphones, as well. We tend to use them often, but never think to give them a good clean, and then we wonder why our microphones muffle.

Well, if we are not capable to clean our microphones on a regular basis, then muffled microphones are the least bad thing that can happen to the microphone you are using.

The importance of hygiene when it comes to everything is crucial, especially if we are talking about audio equipment.

These gadgets can get very filthy since we speak into microphones and our mouths quickly spread germs. Handheld microphones are another item that is routinely shared, utilized, and held by various individuals.

This results in spit, sweat, makeup, and skin particles landing on the devices, even if you can’t see them.

Your microphone will accumulate dirt if you don’t clean it frequently. By opening the top half and peering inside, you can tell if your audio equipment has a build-up. If you decide to ignore this accumulation over and over again, the particles will keep gathering and your device’s sound may start to become muddled.

This is because accumulations in a mic can dramatically lower its frequency response, which will prevent the device from operating to its full potential. Therefore, you should check to determine whether your gadget has a build-up or if it is making an odd sound and hasn’t been cleaned in a while.

How Should You Disinfect Your Microphone?

Well, first of all, let’s get one thing straight, first and foremost you should be aware of what kind of microphone you have because I am sure that I have mentioned somewhere in one of my articles that there are two types of microphones, condenser, and dynamic mics, They both require different ways of cleaning them so I’m going to explain the microphone cleaning methods.

What’s the best way to clean a condenser mic?

It is well known that condenser microphone cleaning is a little more challenging than a dynamic one. This is because condenser devices are more delicate, necessitating extreme caution.

The tools

The tools that you will need in order to clean a condenser mic, are A toothbrush, cleaning surface disinfectant wipes, paper towel roll, and washing liquid which is typically used to wash dishes. Just be careful of spraying any kind of liquid on the microphone capsule or its electronics.

Grille Removement

If you can, carefully separate the grille from the device’s body, if the grille can be removed. It could be laborious and require taking out screws. Make sure the equipment itself never comes into contact with any liquids or water. Even a small bit of moisture might permanently harm the gadget.

Grille wash

If the device’s grille can be removed, remove the windscreen as well. Just as you would for the dynamic device, start cleaning the grille with a toothbrush and washing solutions. Concentrate on removing any buildup that may be present on the grille by using warm water. In addition, look for any concealed particles in the corners and edges.

If the grille cannot be removed from the device, carefully scrape it with a dry toothbrush. Allow any dirt and debris to fall out onto the ground by holding the gadget upside down. Avoid forcing dirt or toothbrush bristles through the grille because doing so will cause them to become caught in the chamber indefinitely.

Drying of the grille

If your device has a removable grille that you were able to wash, make sure it is totally dry before reinserting it. This is a very important step since a condenser device will be severely harmed by a moist grille. To make sure it is completely dry, you can use a paper towel, but I also advise using a hair dryer or letting it air dry.

Windscreen wash

Once you’re certain that all of the buildups have been removed, you should start washing the windscreen using water and washing detergent. As previously said, before reinstalling the windscreen on the device, you must ensure that it is totally dry. This has major significance. The easiest approach to dry the windscreen is to let it air dry overnight or use a hair dryer.

Clean the microphone’s body

Last but not least, you have to clean the mic body with disinfectant wipes.

What’s the best way to clean a dynamic mic?

The vast majority of people who utilize microphones assert that dynamic microphones are the simplest to maintain. Cleaning microphones is generally not too difficult because most of them include a grille that is relatively simple to unscrew and separate from the device’s body.


The tools that you will need in order to clean a dynamic mic, are: Washing liquid which is typically used to wash dishes, a toothbrush, cleaning surface disinfectant wipes, and a paper towel roll.

Grille removement

The grille must first be carefully removed from the device’s body. With a hard twist and unscrewing, it ought should be simple to remove. Use moderate force; otherwise, you risk irreversibly damaging the gadget.

Remove the foam windshield as well after successfully removing the grille. You can start noticing spit buildup on the foam windshield and lipstick, grime, and saliva buildup on the grille.

Grille wash

Use the toothbrush to apply warm water and dishwashing liquid next. To remove any buildup, start cleaning the device’s grille. Be careful, and be sure to reach all the corners and edges.

Dry the grill

Before re-attaching the grille to the device, completely dry it using paper towels. If you don’t make sure it’s completely dried, the object can rust. If you have the extra time, you can also use air drying.

Windscreen wash

You must now repeatedly wash the foam windshield with water and washing detergent until you are certain that all buildup has been removed. Again, you must make sure the foam windshield is completely dry before reinstalling it on the apparatus. If you need it to dry rapidly, I’d suggest using a blow dryer or letting it air dry overnight.

Clean the mic’s body

Just like with condenser microphones, you have to clean the body of the dynamic microphone, as well, using disinfected wipes.

Things To Avoid When Cleaning Your Microphone

While cleaning your microphone, there are certain things that you have to avoid or tools that you mustn’t use any under circumstances, such as:

  • No Hydrogen Peroxide
  • No bleach cleaning products
  • Do not saturate products with liquid
  • Do not use hand sanitizers to clean Shure products
  • No abrasive cleaning tools (I.E. scrub brush, scouring pad)
  • No rubbing alcohol (Isopropyl Alcohol) on clear plastic parts

Final Words

The whole process of cleaning a microphone seems simple, but as you might have noticed, there is a certain way about doing anything, including microphone clean, so make sure you do it properly and you won’t have any issues with the proper functioning of your microphone.
