We've all suffered from a keyboard that no longer looks like. Coffee Finger grease, dust ... you name it! How do you get it quickly and safely? I recently used a kitchen cloth Muscle. Moist enough to dissolve stains, strong enough to loosen grease and grime, and pliable enough to send between the operation keys ... But here it convenient for the cause! It is almost instantly dry and does not stick when you're done! Your keyboard looks like new!
