Loosen the dust, spray the screen with short strokes of compressed air in a can instead of using one continuous spray.

  • Avoid abrasive sponges – Using harsh tools and sponges to clean surfaces can often damage them.
  • Use a soft cloth – You should only wipe your screen with a soft, lint-free cloth. Gently wipe the screen and avoid scrubbing it.
  • Avoid harsh chemicals – If your screen needs more cleaning power, don’t use harsh chemicals. Using a strong cleaner can quickly ruin your screen’s reflection. Instead, use a 95% warm water solution with 5% mild dish soap. Denatured alcohol can also be used when cleaning vinyl surfaces.
  • Do not air dry – Spotting can be avoided by gently patting the surface dry with a soft towel.
  • Retractable screens – These screens can be rolled up when not in use to keep dust from sticking to the surface. Make sure the screen is completely dry before rolling it back up.
  • Use a small amount of denatured alcohol and a q-tip to stubborn stains. Do not soak the screen because this can leave a permanent stain. Dab any residue with a Q-tip or a clean microfiber cloth.

If your projector screen is retractable, avoid dust and grime by keeping it rolled up when not in use. And pat dry thoroughly after cleaning, so as to never roll the screen up wet.
