After years of decoration, I now find that the wallpaper is yellowing. Is there any solution from the experts? Expert answer: the yellowing of wallpaper is generally divided into the following situations: if the wallpaper is pasted before the wall ash is completely dry when you check in at that time, the alkaline substances in the wall ash are easy to react with the bottom of the wallpaper, making the surface yellow. This phenomenon is difficult to deal with, and the wall needs to be eradicated and rebuilt. If there is yellowing after living for a few years, most of the reason is that the paper is exposed to sunlight and air

expert answer: the yellowing of wallpaper is generally divided into the following situations: if the wallpaper is pasted before the wall ash is completely dry at the time of check-in, the alkaline substances in the wall ash are easy to react with the bottom of the wallpaper, making the surface yellow. This phenomenon is difficult to deal with, and the wall needs to be eradicated and rebuilt. If yellowing occurs after living for several years, most of the reason is that the paper is aged due to exposure to sunlight and air. At this time, you can dip "safety bleach" into a towel and wipe it with clean water after half an hour. (you can first make a small piece of the hidden part of the wall for testing) observe the effect. If the effect is ideal, you can use it as a treatment for all the walls. If some parts turn yellow due to smoking, it is advisable to wipe them with diluted caustic soda (brother's) solution
