What is the right way to clean the projector screen?

Motorized Projector screens are delicate, and any mistake can lead to a damaged screen. As different screens are made up of other materials, you should refer to the manufacturer manual to understand if the cleaning method you are going to adopt is suitable or not.

For example, the Ambient Light Reflective screen should not be scrubbed heavily. It may damage the soft brushes over the screen. Use only compressor air method to clean such type of screens.

Different ways of cleaning the projector screens:

Here are the two recommended ways to clean projector screens:

Never use a towel or a washcloth to clean the projector screen. Take a microfiber cloth and wipe the screen gently. You can use a solution of water (95%) and soap (5%) if you find the screen is very dirty and there is accumulated dirt. Clean the screen from side to side using the moistened cloth.

If the soap solution is insufficient, you can use cleaning solutions like denatured alcohol. Don’t forget to dry the screen to avoid any moisture entering it.

Never use the masking tape by wrapping it around your fingers, as it may lead to scratches on your projector screen. Most manufacturers recommend not to use these masking tapes as they can damage the screen surface.

Tips on Cleaning the Projector Screen:

  1. Prefer compressed air: The compressor air method is the best bet to rely on. Avoid touching the projector screen as much as possible. The compressed can should not be closed more than 1″ from the screen.
  2. Use Gloves: Some oil on your fingertips can be left on screen while cleaning with bare hands. Especially if you have long nails, you may end up scratching the screen. Hence, gloves are your best bet.
  3. Avoid Air Drying: Never spot pat your projector screen, even with any soft towel.
  4. Never Use any Harsh Chemicals: The corrosive chemicals can ruin the screen reflection, and you should avoid it strictly. Always use a mild water solution (95%) and soap (5%). If you are dealing with Vinyl surfaces, use denatured alcohol.
  5. Use Microfiber Cloth: Always use a lint-free microfiber cloth or any other soft cloth to avoid any scratching on your screen.
  6. Avoid abrasive sponge: You should not use hard sponges and brushes while cleaning as it will lead to scratches and even screen damage.
