Your keyboard is one of the dirtiest places in your office or home. You touch it all the time, and probably rarely wash it, leaving it full of dirt, bacteria and viruses. Try this trick for quick and easy keyboard cleaning: soak a Q-tip or small sponge (an eyeshadow applicator sponge on a stick works wonders for this) in white vinegar. Shake off any drips, then drag the sponge gently in between the keys on your keyboard. Use a fresh sponge or Q-tip to clean the tops of the keys. Let air dry. White vinegar kills bacteria, mold and viruses.
