How to Clean a Projection TV Lens
Dust particles in the air can come in contact with the inside of your projection television as well as the outside. Over time, dust can accumulate or build on the lenses within the television. This can affect lens clarity and thus, your projection television's visual quality. Cleaning the lenses inside a projection television will minimize dust build up and allow you to enjoy better picture performance. Cleaning lenses involves care not to scratch or damage them.
