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!
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:
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.
Start using a manual lens blower to clear dust from the center of the lens first, and then continue with the additional bursts.
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.
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.
No. Always use products designed for cleaning lenses. Don’t use alcohol-based cleaning products or other same category products because they may damage the lens and can cause scratches.
No. It is recommended to use the brushes designed to clean the projector lens. Don’t use other brushes because they may scratch your lens.
If you are sure you cleaned the projector lens correctly, then try adjusting the projector’s zooms and focus.
Clean your projector lens as soon as you notice the image is blurry. You don’t need to clean it if the quality of the projected content is clear.
