Take a butter knife to remove the keys.

Make sure you remove them gently.
Look at all the dirt hiding behind the keys

This, you see, is the root cause of certain mysterious kind of flu in your homes.
The next step is to fill a jar with the keys

Make sure you close the lid tightly.
Fill the jar with a dish soap and water.

Shake the jar well, such that it you see the soapy water. Take out all the anger you had over those bacteria that caused the flu.

Then take out all the keys in a container and pour some cold water over them.

The next step is to let the keys dry on a paper towel.

Make sure that you lay the keys flat so that none of the water stays in the keys.
Now it is time to clean your keyboard.

Lay your keyboard upside down and tap it gently so that all the dust goes away.
The compressed air sprays really help blow away all the dust.

Do not forget to wipe off your keyboard with a disinfecting cloth.

Place all the keys back

If you do not remember the position, use a picture of a key board to place the keys at their right places.
