To maintain optimal performance and appearance, regularly clean your keyboard:

• Disconnect the keyboard from your computer before cleaning.
• Use a can of compressed air to remove dust and debris from between the keycaps.
• Wipe the keycaps and keyboard surface with a soft, slightly damp, lint-free cloth. Avoid excessive moisture.
• For stubborn stains, a small amount of isopropyl alcohol on a cloth can be used.
