Eventually every projector lens gets dirty or dusty.

Here are some tips on how to clean your projector lens without damaging it.

Before cleaning:

  • Turn off the projector
  • Unplug the power cable
  • Let the projector cool down. It should be cool to the touch.

Avoid:

  • Abrasive cleaners, solvents or other harsh cleaning chemicals – they can damage the lens.
  • Paper towels or tissues as the hard fibers in this material can scratch the lens while leaving particles behind.

Cleaning a Dirty Lens

  • Get rid of a build up of dirt by using a non-abrasive lens cleaning solution.
  • Avoid alcohol to clean the projector lens.
  • NEVER apply the cleansing solution directly to the lens.
  • Apply the cleaning solution to a soft, dry and lint-free cloth bought at a camera or photography shop. You can also use a proper photographic lens brush to gently wipe the lens surface.
  • Wipe the cloth gently in circular motion.
  • NEVER touch the lens with your finger since oil from your skin can leave a mark.
  • Replace the lens caps in you are not planning on using the projector immediately afterwards.

Getting rid of dust

  • Use a can of compressed air to remove dust from the lens.
  • Purchase the right type of compressed air that is suitable for lens. Check at your local photography store.
  • Be sure to stand at least seven inches away from the lens before spraying the compressed air to avoid cracking the lens.
  • Avoid dusty areas with excessive dirt and your projector will last longer.
