Many an attempt at cleaning a keyboard has ended up with the device worse for the wear. Over-aggressive attempts at cleaning out lint and debris from underneath keys can render them useless, and introducing inappropriate liquids into the equation can damage the devices.
A properly cleaned keyboard will probably work better than one that’s gummed up. HelpWith PCs explains a simple and easy way to clean your keyboard without damaging it or making a big mess.
Don’t forget to unplug your keyboard before starting. For a moderate, low-impact cleaning, your best tool is a cotton swab you dab in isopropyl alcohol. Other options include using compressed air to blow out gunk, a vacuum to suck it up and a dry cloth to wipe it down.
If you want to go deeper, you can use a screwdriver to remove the keys individually, but such a measure is rarely necessary.
