Well, today I decided to clean my computer keyboard. It's something I've been putting off for a while, one of those jobs whilst not very hard to do helps make your computer more aesthetically pleasing. Quite frankly I don't like cleaning it out often and if looking at it upside down it turns into a kaleidoscope with special floating objects. Did you also know that the quantity of bacteria on a computer keyboard is more than that of a toilet seat. Ewww. Seriously!

Now, the job itself isn't that hard to do, just more of a timewaste and mess around with taking things apart and meticulously clean them so there is less to look after the next time. For tools, you don't really need much, just a couple of simple screwdrivers should do it and when the keyboard is fully dissassembled some soapy water and a sponge to rub everything down. I gave everything a good rub over with a scouring pad and then once I did this I dried them off and assembled the keyboard in stages

I've added some comparison pictures below for you to see the progress as I cleaned it. What I would recommend once it has been cleaned is to make sure you test out each individual key on the computer to make sure you have assembled it in the correct order. If you need a point of reference I have added a standard picture below as well incase you need to check the placement of where letters go in keyboard.

Additionally one of the benefits of cleaning your keyboard, aside from the health benefits is that it will usually respond better to the typing input. The germs and grease generally form a sticky bond with all the letters and with it removed the keys have a nice solid feel to them again when typing with them.


  • Pop all the buttons off the keyboard
  • Unscrew all the screws from the keyboard and carefully dismantle
  • Remove the internal components being careful not to damage the membrane
  • Clean the plastic components and keys inside of a warm soapy mixture
  • Firmly dry keys and build them again on the keyboard one at a time for springs, fit them slightly and add pressure. This pressure will align the springs
  • Once all the keys are installed place the membrane and all internal components inside the keyboard
  • When everything is replaced resync the keyboard if wifi as the batteries will have been removed
  • Once removed, logon to the computer and test all of the keys to make sure they're in the correct order
  • If any keys are incorrect, pop them off with a screwdriver and reinstall, a standard QWERTY layout is listed below for a point of reference

The first step is to remove all the keys from your keyboard and collect them in a pile, you can see from the ones I removed on my keyboard they had bits of everything like grime, hair, nails and bits of food etc. They're manky, the cleaned ones I put inside a blue container

A picture of the keyboard after I removed the keys on the keyboard and a picture on the right after cleaning it with soapy water, it wasn't 100% cleaned but a lot cleaner that it was originally.

keys as you go

When I assemble the keyboard I prefer to do it as I go so that I don't have lots of keys hanging around, I replace them as I go along

A before an after of the keyboard cleaning progress, you can see the grime and dirt formed around the spacebar etc.

This is a secondary before and after of the keyboard to get an idea of the difference a bit of cleaning can make. This should really be a thing I do at least once a year to maintain the overall cleanliness of your keyboard, it's about an hour long job overall, but worth it to maintain your PC to a healthy and cleanly standard.



Remember when you are assembling the keyboard to place the membrane down on top of the rubber component and make sure the screws are put in the keyboard firmly. If your keyboard is a wireless keyboard, you may need to resync the wireless connections by pressing the button and find wifi equipment. This will reconnect the keyboard and hardware
