Check whether there is oil or dust on the projection lens; || Use a soot blower to blow off the dust on the lens surface; || Use alcohol and clean paper to wipe off the stain on the lens surface.
What to do if the projectior lens is dirty
If the projection lens is dirty, it will seriously affect the image quality. At this time, the lens of the projector needs to be cleaned. Cleaning the lens is divided into two steps: first, blow off the dust on the surface, and second, wipe off the stain on the lens surface. So what should I do?
1. How to blow off the dust on the surface of the lens,
use professional soot blowing tools, such as air gun (supplied by high pressure gas from the air pump) and blower balloon (also known as blower / air tank, choose the one with good elasticity and large volume), etc. Dust off the surface of the projector lens. If you can't find a tool, there is no problem blowing hard with your mouth.
2. How to wipe off the stains on the surface of the lens
Use alcohol and wipe paper, if alcohol can not be found, just use Erguotou together. The cleaning paper chooses ultra-microfiber and nanofiber cloth, which is ideal for soft lens cloth with soft texture, no lint-free ball, no lint and repeatable cleaning. Note that you can't use ordinary paper towels, which are mixed with some large particles of impurities, which can easily scratch the lens. Use a folded mirror paper stick and wipe it with alcohol. When wiping, wipe away from the center of the lens in a spiral outward circle. Do not go back. After wiping once, place the test paper on the edge of the lens to remove the dust. Can't wipe back and forth, so the dust is brought back to the lens. After sequentially wiping the surface, the cleaning of the projector lens surface is completed.
