Unlike a computer monitor the LCD is not made of glass therefore requires special cleaning procedures. When cleaning the LCD screen it is important to remember to not spray any liquids onto the LCD directly, do not use a paper towel as it can cause the LCD to become scratched. To clean the LCD screen we recommend that you use a soft cotton cloth if a dry cloth does not completely clean the screen you can apply rubbing alcohol to the cloth and wipe the screen with the damp cloth. Rubbing alcohol is actually used to clean the LCD before it leaves the factory. Dirt, dust and hair can build up causing the keyboard to not function properly.
Many people clean the keyboard by turning it upside down and shaking.
A more effective method is to use compressed air. Compressed air is pressurized air contained in a can with a very long nozzle. Simply aim the air between the keys and blow away all of the dust and debris that has gathered there. The following are a few recommendations to help prevent a keyboard to become bad once a substance has been spilt within it. First turn the computer off immediately.
