How to clean your projector lens properly



Dust on your projector lens? Here’s how to clean it.


Your projector lens is similar to a camera and should be cleaned the same way. You can get everything you need to clean your projector lens at a camera store.

Before cleaning:

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

Keep it clear

Avoid permanently fogging your lens. Never use alcohol or other abrasive solvents to clean your projector, especially your lens. Avoid putting lens cleaner directly on the lens as well. Both of these action will create a permanent haze giving your image a foggy look.

Proper steps

Step 1: Used compressed air or a small blower brush to remove any dust or debris from the lens. Don’t try cleaning the lens before using the compressed air or you can scratch the lens. Be sure to stand at least seven inches away from the lens . Purchase the right type of compressed air that is suitable for lens.

 Step 2: If the lens is still dirty, use a camera microfiber cloth to gently wipe the lens in a circular motion staring from the center. If the lens is sticky, then put one or two drop of lens cleaning solution onto lens tissue and gently wipe the lens – again in a circular motion. You can also use a carbon-based lens using its soft brush pen to clean the lens. Avoid using rags that will leave any lint. Paper towels or tissues as the hard fibers in this material can scratch the lens while leaving particles behind.

Step 3: Let the lens dry if you have used the solution. Give another blast to compressed air to remove any dust from the cloth. Avoid touching the lens directly. Oil from your fingers will leave a mark.
