Eventually every projector lens gets dirty or dusty.
Here are some tips on how to clean your projector lens without damaging it.
- 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.
- 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.
- 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.
