Tips On How To Clean Your Projector Lens At Church

How To Clean Your Projector Lens – The Short Answer

  • First, you need to unplug the projector from the power supply.
  • Ensure the projector is cool by giving it at least 20 minutes or more for it to cool off.
  • Open the projector casing.
  • Use a can of compressed air to blow off the projector lens.
  • Alternatively, you can use lens brushes to accomplish the same thing as a can of compressed air.
  • Use a microfiber cloth and lens cleaner to wipe off the lens in a circular motion.

What to Think About When Cleaning a Projector Lens

If the image quality is less than ideal, that’s a sign it may be time to clean or replace the lens in your church projection system. If unusual dots appear in images, this might mean dirt has gotten trapped inside of the projector lens and needs to be cleaned out.

However, you don’t want to use the wrong products or techniques when cleaning the lens. Cleaning a projector’s lens surface is different than cleaning your sunglasses or eyeglasses.

Things You Should Do When Cleaning A Projector Lens

  • Use a microfiber cloth and lens cleaner to wipe off the lens in a circular motion.
  • Always use products that are specifically labeled to clean lenses.
  • Always keep your cleaning products, like your microfiber wipes and lens brushes, in safe places where they will remain clean. A dirty lens brush is useless.
  • Always spray the compressed air canister in short bursts to avoid damage to the glass.

Things You Should Avoid When Cleaning The Projector Lens At Your Church

  • Never use a t-shirt or other types of cloth to clean your lens; it WILL scratch the glass, no matter how soft it is. Make sure you use a clean microfiber cloth.
  • Do not touch the glass with your fingers. Fingerprints are the hardest to remove and affect your picture quality the most.
  • Avoid using household products on lenses because they could cause irreversible damage or discoloration.
  • Do not use your breath to wipe the lens; the acidity of your breath can damage the coating on the glass. You’re spitting all over it.
  • Never clean while the projector is still plugged in or even turned on – always wait until it has cooled off for at least 20 minutes before cleaning. You could get shocked, and you want to avoid these types of powerful experiences in church.

When To Replace Your Projector Lens

If the projector is more than ten years old, it may be time to replace your projection system. Projectors are getting cheaper and better every year, so you should consider purchasing a new one if yours hasn’t been replaced in over five or six years. Usually, a projector bulb costs more than buying a new one.

Also, watch out for problems with color balance, faded colors, blurred images, and overall poor picture quality – these could all be signs the projector lens is damaged and needs to be replaced.
