How Do I Clean The MacBook Pro Keyboard And Trackpad?
Before cleaning, make sure your computer is shut down and unplugged. You should also remove the battery. Wipe the keyboard and trackpad with a disinfectant and then damp, lint-free cloth to dry the surface.
Do not use any chemicals that contain bleach and avoid cleaning sprays. Make sure the cloth is soft and just a little damp. It's important that it not be too wet.
