I recently discovered a solution to all those bits of dust that collect in the various components of my Home Theater. Basically I bought a decorators brush (the softer the better) I then used electrical tape to cover all the metal and sharp edges that might scratch anything. Use the brush to get into all the cracks/crevices, it works a treat. My system looked brand new after a few minutes. It works on the remote controls and in the corners of the TV screen where dust collects. By the way it also works in a car.
