Clean your projector lens properly

Eventually every lens gets dirty or dusty and needs to be cleaned.




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.




  • 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.

  • Get rid of a build up of dirt by using a non-abrasive lens cleaning solution.
  • Isopropyl alcohol can also be used 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.
