Dust may seem harmless, but it’s the archenemy of electronics equipment. It can effect the performance of computers, VCRs and, yes, CD and DVD players. The inside of a disc player is not airtight. Every time you open the disc tray or put in a disc, the laser lens is exposed to airborne contaminants. And just like a television, static builds up on the lens, attracting dust like a magnet. The Ultra Pro Lens Cleaner uses carbon fiber technology to dissipate static and eight staggered brushes that progressively pass over the laser lens to clean the entire surface. The cleaning process takes only a fraction of a second and can actually prolong the life of your disc player. The Ultra Pro Lens Cleaner works to protect the most delicate electronics components and help you set the levels on your audio system to best perform in its surroundings.
