Clean a keyboard
step 1 What you need
You will need:
a keyboard
Rubbing alcohol
Cotton swabs
Something to rub the gunk onto. I used some toilet paper.
A flathead screwdriver, or something similar
step 2 Take off the keys!
Unplug your keyboard. I don't think anything bad will happen if you don't, but still. Better safe than sorry.
Take your flathead screwdriver (or similarly shaped tool), and stick it under one of the corners of the key. It helps if you have a part of the screwdriver touching the edge of the "pit" in the keyboard. Cover the area with your hand, so that the key doesn't go flying. Now just push down on the screwdriver, using it kind of like a lever.
Now just repeat it over 100 times for the rest of your keyboard. Make sure that you organize your keys, so that when you put them back, they're in the right spot. I recommend you do 1 section at a time, so there's less to keep track of. If you do manage to mix them up, here's a good image to use to put them back.
step 3 Clean it!
First, take your keyboard to a garbage can, and shake. Let the solid particles fall into the garbage can. Now take a cotton swab, and soak it with the rubbing alcohol. Clean everything out. Rub the key, and then rub the pit. This should dis-infect and clean them both. Now rub the gunk off onto the paper. Don't worry about the alcohol getting inside the keyboard, it evaporates really quickly.
step 4 Stick the keys back in
Now that all the keys are clean, put them back in. Use a moderate amount of force. Make sure that it's aligned properly, and push down. You should feel and hear a loud click of sorts, and it should now work.For the keys with two posts, push in the side with the full post first. Then, push the other side in. Now test the key, and make sure it feels like it should.If your some of your larger keys (like the spacebar, enter, etc.) has a metal bar, this is going to be harder. Make sure the keys to the side of the key aren't on yet. This will make it easier. Now, detach one side of the metal bar. Place the bar in the plastic clips. Now align the post with the well, and stick it in half-way. Now just stick your finger under the side with the un-attached bar, and clip the bar back into the clip on the key.
