How To Clean BenQ Projector Lens? 5 Simple Steps

Your BenQ projector is a valuable tool for delivering impressive presentations or enjoying immersive entertainment experiences. However, over time, dust, fingerprints, and smudges can accumulate on the lens, affecting the clarity and sharpness of your projected images. Regularly cleaning your BenQ projector lens is essential to maintain optimal image quality and ensure a satisfying viewing experience. In this blog article, we will guide you through five simple steps to effectively clean your BenQ projector lens. By following these steps, you can remove debris and restore the lens to its pristine condition, resulting in clear, vibrant, and uninterrupted projections.

Step 1: Prepare the Cleaning Materials

Before starting the cleaning process, gather the necessary materials. You will need a clean microfiber cloth, lens cleaning solution (specifically designed for optical surfaces), and a blower or compressed air canister.

Step 2: Power Off and Unplug the Projector

Ensure that the BenQ projector is powered off and unplugged before attempting any cleaning. This step is crucial for your safety and to prevent any damage to the projector.

Step 3: Remove Loose Dust with a Blower or Compressed Air

Using a blower or canned compressed air, gently blow away any loose dust particles from the lens. Hold the canister upright and use short bursts of air to dislodge the dust. This step helps prevent scratching the lens during the cleaning process.

Step 4: Apply Lens Cleaning Solution to the Microfiber Cloth

Apply a small amount of the lens cleaning solution to a clean microfiber cloth. Avoid spraying the solution directly onto the lens, as it may seep into the projector. The lens cleaning solution is specially formulated to safely remove stubborn smudges and fingerprints.

Step 5: Gently Wipe the Lens

Using the dampened microfiber cloth, gently wipe the lens in a circular motion. Start from the center of the lens and work your way outward. Apply light pressure to remove any remaining smudges or fingerprints. Be careful not to press too hard or scrub vigorously, as it may damage the lens.

Additional Tips:

  • Avoid using rough or abrasive materials, such as paper towels or tissues, as they can scratch the lens.
  • Never use household cleaners or solvents, as they can damage the lens coating.
  • Clean the lens periodically to prevent buildup and maintain optimal image quality.

How do I clean my Benq projector filter?

Cleaning the filter of your BenQ projector is an important maintenance task to ensure optimal airflow and prevent overheating. Here’s a step-by-step guide on how to clean your BenQ projector filter:

  1. Power off and unplug the projector: Before attempting to clean the filter, make sure the projector is turned off and unplugged. This is crucial for your safety and to prevent any damage to the projector.
  2. Locate the filter: The filter is typically located on the side or bottom of the projector. Refer to your projector’s user manual for the specific location of the filter.
  3. Remove the filter: Depending on the model, the filter may be secured with a latch, screw, or clip. Carefully remove any fasteners and gently slide or lift the filter out of its compartment.
  4. Inspect the filter: Examine the filter for visible dust, dirt, or debris. If the filter is heavily soiled or damaged, it may need to be replaced. Refer to the user manual or contact BenQ customer support for guidance on obtaining a replacement filter.
  5. Clean the filter: If the filter is dirty but still in good condition, you can clean it. Use a soft brush, such as a small paintbrush or a soft-bristled toothbrush, to gently brush off the accumulated dust and debris. Start from one end and work your way across the entire surface of the filter. Ensure that you remove all visible dirt particles.
  6. Air blow or rinse the filter (optional): If the filter is still not completely clean after brushing, you can use compressed air or gently rinse it under running water. If using compressed air, hold the canister upright and use short bursts of air to blow away any remaining dust. If rinsing the filter, use lukewarm water and gently rinse it under a faucet. Be careful not to use excessive force, and allow the filter to air dry completely before reinstalling it.
  7. Reinstall the filter: Once the filter is clean and dry, carefully slide or place it back into its compartment. Ensure that it is properly aligned and securely fastened with the latch, screw, or clip.
  8. Perform a test: After cleaning and reinstalling the filter, power on the projector and run it for a few minutes to ensure proper airflow and functioning.

Additional Tips:

  • Consult your projector’s user manual for specific instructions on cleaning and maintaining the filter, as different models may have slight variations.
  • Clean the filter regularly, especially if you use the projector in dusty environments or frequently.
  • Consider establishing a maintenance schedule to ensure timely filter cleaning and replacement if necessary.

By following these steps and regularly cleaning the filter, you can maintain optimal airflow, prevent overheating, and extend the lifespan of your BenQ projector.


By following these five simple steps, you can effectively clean your BenQ projector lens and ensure optimal image quality for your presentations or entertainment. Regular maintenance and cleaning will help you enjoy clear, vibrant, and uninterrupted projections.
