Cleaning accessories for most electronic items tend to focus mostly on the exterior with little or no attention paid to the interior workings of the device. DVD lenses need specialized care as dust has a way of accumulating on them. Lens cleaning kits previously have not had much success as they would require manual control, i.e. physical manipulation by hand. The most effective way to clean them however, remains usage of a disc equipped with a brushing system to gently wipe away accumulated dirt and dust.
