Small non-invasive stains, using an eraser

When there are relatively small pieces of non-invasive stains, the better method is to wipe them gently with an eraser. However, if the quality of the rubber is not good enough or the rubber with color, it may not be completely erased and leave a pool of imprints, so pay special attention to the use of pure white high-grade rubber, which is easy to buy in stationery stores. As for the method of erasing, I will know what to do when I recall the warm situation when I revised my homework.

Liquid stains or stains have a large area, use detergent

First of all, to ensure that the PH value of the detergent is as neutral as possible. Because the screen base layer and coating, most of which are resin or rubber materials, are susceptible to corrosion and discoloration.

Second, do not use oily cleaners and cleaners with a brightening agent, such as the blue pearl and the like. You can choose water-based, volatile foam cleaners, which have no damage to the screen. You can also choose from cleaners such as collar cleaners in supermarkets.

Finally, it is very important to use what tools to clean the projector curtain. Because the surface of the curtain is actually uneven, it is necessary to choose a tool with as small molecular particles as possible, such as polymer sponge, which is very small and can fully remove the dust in the pit after the cleaning agent is wet and softened. On the contrary, the use of rough sponge or towel, it is difficult to clean the small stains in the recess of the curtain.

Oily stains, use a cotton ball dipped in a small amount of degreasing solvent

This kind of situation is more difficult to deal with, if not handled properly, there will be great risks. Only use cotton ball dipped in a small amount of degreasing solvent, quickly erase desalination, then use more pure water or neutral detergent dilution and dry as soon as possible. But for some special stains, especially in some party occasions, spray on the color stains, there is no effective way to clean up. Therefore, before such a lively scene appears, it is best to put away your projector curtain so as not to hang up the lottery.

The bead curtain cannot be cleaned

Commonly used projector curtain, according to the curtain material can usually be divided into: white plastic curtain, glass bead curtain, metal curtain and so on. In general, in addition to the glass bead curtain material (Glass Beaded) does not have the characteristics of cleaning, other curtain materials can basically choose the appropriate cleaning method according to the degree of contamination.

The glass bead screen is widely used because of its high gain and moderate price. However, the glass bead curtain material, because the surface has a fine quartz coating, the stain is easy to invade the gap between the particles, it is difficult to clean up. In addition, the surface of the quartz crystal, itself is also easy to stick to the stain, that is, the occurrence of secondary pollution. Therefore, when using the screen of the glass bead curtain material, you should be extra careful and caring, and it is best to put it away in time when not in use.
