chemicals, Maxell lens cleaner uses its exclusive patented Wind Funnel cleaning technology. The disc rotates to generate an air stream that catches the two holes in the disc. The resulting air shower removes dust particles from the lens without damaging it. The multi on-screen interactive program allows you to choose options to guide you through the cleaning process, run equipment performance tests (including a polarity and surround sound test) and other disc features. The BR-LC lens cleaner is compatible with all HD DVD players, DVD players, XBOX 360 and Playstation 3.  (less)
