Maintenance of Keyboard.

• Shutdown your PC and remove the main plug.
• Unplug the Keyboard and hold it upside down to release any debris from in between the keys(pressing the key is a good way to clean it.)
• Now, take one of the cotton buds and put a couple of drops of the cleaning fluid on it
  
• Use the cotton bud to clean the sides of the keys.
• After cleaning the sides of the keys take your free cloth and dampen it with your cleaning fluid.
• Do not put the liquid directly on the keyboard.
• Give the surface of the keyboard a good wipe over using the cloth to trace the contours of the keys.
• When you have finished, give the keyboard a wipe over with the dry cloth/duster.
• After clean the keyboard USB cable.
• You should now have a nice clean Keyboard.
