So if PVC projection cloth dirty or discolored and, then, to the image must be presented the projector will be affected. So how to clean the projector screen? Here we introduce several kinds of methods:
The eraser can go unless invasive small stain When there is a small piece of non invasive stain, compare good method, is to use the eraser to wipe gently. However, if the rubber quality is not good enough or is colored rubber, may be not completely erase and left a print beach, so pay special attention to choose pure white when using advanced rubber, this in the stationery shop, it is easy to buy.
Use detergent to remove the stain liquid class or stain with larger area First of all, the PH value is neutral as far as possible to ensure that the cleaner. Because screen and coating at the grass-roots level, most is resin or rubber materials, etc., are vulnerable to corrosion. Second, do not use oily cleaner and cleaner with bright agent, can choose water, can be volatile foam detergent, no damage to the screen.
