If you have an older keyboard with thick keys, then pry off every key with a screwdriver. Then wash the keys in a soapy tupperware. Wipe down the keyless keyboard with a soft cloth that's damp. Then put the keys back on after they dry. It should give you a good two years of clean keyboard.😎
However, if you have a laptop or one of the newer iMac or Mac Pro keyboards then it is much easier. You should just wipe it with a soft damp cloth and you're good! 🙂🙂
