Keyboards are a big part of our computers. They help us communicate when we are writing documents or playing games.

But have you ever had to work on a computer that had a keyboard that looked like it hasn’t been cleaned in months? I don’t mean a keyboard with some dust bunnies underneath, but one with dried potato chip crumbs, grease, or sticky syrup spills.

If you have ever had the misfortune of working on one of these machines, you quickly realize it’s a bad situation to be in. Not only will a dirty keyboard hinder you from your work, but it can also be a breeding ground for germs and could literally cause you to get sick.

So what’s the solution? Clean a dirty keyboard with baking soda?

Yes! You can do that, and it is pretty simple.

This article will show you how to clean a filthy keyboard by using baking soda with other household items.

Let’s begin.

3. Use a dry microfiber cloth to wipe the surface of the keyboard. This should remove some of the loose dust and grime off. Also, check if there are damaged keys that need to be replaced.

4. Remove the keys. If your keyboard keys are removable, use a flat head screwdriver to gently pop them out one by one. Check your keyboards manufacturer’s guide when in doubt. Bonus Tip: Take a picture of the keyboard before you remove the keys. You can use the picture as a reference when placing the keys back later.

5. Mix 2 liters of water and 4-6 tablespoons of baking soda in a small basin. Put the keys in the water. Let them soak for 15-20 minutes.

The Dangers of a Dirty Keyboard

You probably spend eight to twelve hours on your computer every day, so using a dirty keyboard can be a serious issue. 

Studies have shown that there are more harmful bacteria on the QWERTY keys than there are on a toilet seat. That means that it’s vital to always clean your keyboard. 

It’s also important to wash your hands before and after you use your keyboard, because if you don’t, then there’s a high chance that you could get sick from germs. It’s also a good idea to keep a bottle of hand sanitizer on your work desk in case you need to sanitize your hands.

The dust on your keyboard may look harmless, but it can cause a lot of problems. You see, dust build-up accumulates over some time and reduces your keyboard’s functionality, and with that reduces your ability to do your work efficiently. Dust also triggers allergies, so it’s best we minimize our exposure to it.

3 Tips to Keep Your Keyboard clean

  1. Don’t eat and drink in front of the keyboard. Food debris can get lodged in between the keys. If you really gotta chow in front of the computer, keep a reasonable distance between you and the keyboard.
  2. Don’t touch the keyboard with dirty hands. Wash those cheesy fingers before typing. 
  3. If you notice your keyboard is getting a little dusty, use a feather duster or vacuum cleaner. 


Regularly cleaning your keyboard keeps it in tip-top shape while at the same time keeping the germs away.
