How to Clean a Projector Lens in 4 Easy Steps

Last Updated on May 27 2022

If you own a projector and have noticed the image quality getting blurry, this could be because you have not cleaned the lens recently. Perhaps you might have used your shirt sleeve to wipe it a few weeks ago, but this is not an effective way to clean the lens!

Before You Start

If you have used the projector before, turn it off and let it cool down for 30 minutes to an hour. If it is still hot, don’t clean it yet. Hot lenses are brittle, making them more prone to scratches.

Here is a list of things you will need:

Once you have those items, you are ready to begin cleaning the projector lenses by following the following steps:

1. Turn off and unplug the projector.

After you turn off the projector, unplug it. Make sure the projector is cool before you start cleaning it. Then, take the projector and slant it down so you can blow on the lens from underneath.

2. Use a manual lens blower.

Start using a manual lens blower to clear dust from the center of the lens first, and then continue with the additional bursts.

3. Use a lens brush and lens cleaning paper.

The lens brush helps you clean the projector without damaging it. Brush the lens in a circular motion starting from the center. Repeat the same actions but now with a lens cleaning paper. Once again, start from the center and in a circular motion.

However, if you notice that your projector lens is clean after completing this step, you don’t need to follow the last step. So, look at your projector lens and act accordingly to it.

4. Use a no-lint microfiber cloth.

Spray the lens cleaner directly to the no-lint microfiber. With the moistened cloth, carefully wipe the lens in a circular motion starting from the center. If the projector lens has spots, you may need to moisten another cloth and repeat the same circular wiping motion.
