A keyboard is an input device that is frequently used almost every day. Because of the structure of the keyboard, dust or small things, such as hair, can easily accumulate under the key caps and very hard to be cleaned. Also, during daily using, many bacterium grow on the keyboard. Having a clean and sanitary keyboard can improve your experience using computers. If you have a membrane keyboard for your computer and it is dirty, this instructable will show you how to deeply clean it steps by step. This process only takes less than 30 minutes and it is really simple and doable at home.

The tools you will need are:

· A membrane keyboard

· A Phillips screwdriver

· A slot screwdriver

· An used toothbrush

· Sanitizer (optional)

Step 1: Open Up Your Keyboard

  1. Turn the keyboard upside down and use a Phillips screwdriver to remove all the screws at the back.
  2. Insert the slot screwdriver into the space bewteen top and bottom pieces at sides and open it up. You should hear a snap that means it is opened.
  3. Detach top and buttom pieces. Put the buttom piece aside because we are not going to use it during cleaning. Caution: the bottom piece contains sensitive circuit sheet, so be careful when handling it.

Step 2: Remove Keycaps

  1. Take a photo of your keyboard before removing keycaps. That would remind you if you forget the their poision when you assemble them back.

  2. Turn the top piece upside down. Leave some space between the piece and the table, so keycaps are able to come down.

  3. Use the top of the slot screwdriver to push the little foot of each keycap. Note Space key and Shift keys have a little metal rod under the cap because they are longer than other keycaps.

  4. Leave the enter key on the top piece, because it has two metal rod under the cap and is hard to put back on.

Now you should have all the keycaps removed, and you can see there are many dust and dirt on the top piece.

Step 3: Wash Keycaps

  4. Place keycaps at ventilated place and let them air dry.

After all the keycaps and the top piece are totally dried, you can move to the next step.
