What should I do if the projection screen is moldy? What to do if the projector screen is yellow

1. For small pieces of non-wetting stains, use an eraser.

When there are relatively small non-wetting stains, it is better to gently wipe them off with an eraser. However, if the quality of the eraser is not good enough or the eraser is colored, it may not be completely erased and leave a puddle of imprints, so pay special attention to the use of pure white high-grade erasers.

2. If the liquid stain or stain area is large, use detergent.

1.Make sure the pH of the detergent is as neutral as possible. Because the screen base and coating, most of which are resin or rubber materials, are susceptible to corrosion and discoloration.

2.Don't use oil-based cleaners and brighteners like Bead Franc. You can choose water-based, volatile foam cleaners, which have no damage to the screen.

3.It's important to know what tools you use to clean your projector screen. Because the surface of the curtain is actually uneven, it is necessary to choose a tool that has as small molecular particles as possible, such as polymer sponge, which is very fine and can fully remove the dust in the pit after the detergent is moistened and softened.

On the other hand, use a rough sponge or towel, which is difficult to clean the fine stains in the recesses of the curtain.

3. For oily stains, use a cotton ball dipped in a small amount of degreasing solvent.

This situation is more difficult to deal with, and if it is not handled properly, there is a great risk. Only use a cotton ball dipped in a small amount of degreasing solvent first, quickly wipe off and desalination, and then dilute with more pure water or neutral detergent and blot dry as soon as possible. However, there is no effective way to clean up some special stains, especially the colored stains sprayed on some party occasions.

So before this kind of lively scene happens, it's best to put away your projector screen quickly to avoid hanging colors.

4. The glass bead screen cannot be cleaned.

Commonly used projector screens can be divided into: white plastic screen, glass bead screen, metal screen and so on. In general, except for the glass bead curtain material, which does not have the characteristics of cleaning, the other curtain materials can basically choose the appropriate cleaning method according to the degree of fouling.

Glass bead curtain, because of its high gain and moderate gain, is widely used. However, because of the fine quartz coating on the surface, the stain can easily penetrate into the gaps between the particles, and it is difficult to clean up. In addition, the quartz crystals on the surface are also easy to be stained, that is, secondary pollution occurs.

Therefore, when using the screen of 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.

Do not scrub, spray with diluted dish soap to rinse.

It would be nice to put it in the end and volatilize.

After a period of use, the projector screen is prone to yellowing. This affects the quality of the projection and also affects the viewer's visual experience. Here are some workarounds:

1.Use a special curtain cleaner: You can go to a specialty store to buy a curtain cleaner and clean the screen according to the instructions on the manual. Care needs to be taken not to allow the detergent to spill on the projector lens and cause unnecessary damage.

2.Use a mild detergent: If you don't have a special screen cleaner, you can use a mild detergent, such as light salt water or neutral detergent, etc., and gently apply it to the curtain, and gently scrub it clean, be careful not to scrub it forcefully to avoid damaging the curtain.

3.Exposure screens: Exposure to the sun for a period of time can help whiten the screen and kill bacteria. However, be careful not to expose to the sun for too long, so as not to cause damage to the screen.

4.Microwave heating: Put the wet curtain in the microwave and heat it for 1-2 minutes, which can kill bacteria and eliminate odors, and also help the curtain turn white.

However, caution is also required with this method, as excessive heating may cause deformation or damage to the screen.

In conclusion, there are many ways to keep the curtain clean, and you can choose the one that suits you according to your individual situation. When using the projector screen, it is necessary to pay attention to keeping it clean and cleaning it regularly, so as to ensure the clarity of the projection screen and the audience's good visual experience.
