RE: Lens Cleaning CDs

CD lens cleaners are only slightly more useful than DVD rewinders. They are basically discs that contain a small brush and a TOC that directs the optical drive to put the laser where the brush is. Sounds great in theory, but in practice it is very unlikely to solve any read issues.

When a music/movie disc is spinning over the lens(often in excess of 1000 rpms) a small breeze is created that keeps the top of the lens pretty much free of small particles anyway. If the device is being used in a high dust area the particles will be swept into the mirrors and lenses inside the optical pickup block where no cleaning disc can reach. The only issue that cleaning would ever really fix is when just the top of the lens is dirty from being smoked around. A cleaning disc may help slightly, but is far from optimal. Think cleaning dirty glasses with a hair brush.

99% of the time, the drive will require disassembly and possible replacement of parts once it starts having read issues.
