How to Clean Video Projectors
As an owner of a video projector you should clean the equipment on a regular basis because dust and smudges can ruin the pictures' quality. Green fuzzy patches, called "dust blobs," may appear visibly in the screen in dark passages. Dust blobs are relatively rare, but cleaning your projector involves both the projector screen and the projector lens and case.

Tips & Warnings
Clean or change projector filters every 300 hours for normal conditions.
Use a can of compressed air to help remove "dust blobs" in filters.
Avoid using compressed electronic air to clean projector lens, as they may leave fluid that can cause lens spots.
Use a lint-free cloth similar to the kind use for glasses or electronics to clean the projector screen.
Purchase air bulbs from a camera store or drug store.
Smoke-filled and dusty environments usually require you to clean your projector filter monthly.
Dirty projector filters usually cause the equipment to run hotter, which may cause the projector bulb to burn prematurely.
Never use products like Windex to clean your projector screen, as they can cause residues to form that significantly degrade your screen's quality.
