What to do if the wallpaper becomes moldy?

First of all, if the area is relatively large or there are many, and you feel that even if it is repaired, it will not look good and you want to change the style, then simply replace it;

If it's not very big, your wallpaper quality is pretty good and there's still time to remedy it. It is first recommended to wipe it with soapy water or detergent. If that doesn't work, wipe it with a cloth dipped in disinfectant alcohol. If it's not serious, you can remove the mold by wiping it for two or three times.

Another way to remove mold is to use bleach. But it can easily irritate the skin, so be sure to wear rubber gloves when using it and wash it with water. Some people may be afraid of using bleach, fearing that the original color will be removed. Then use some mildew remover specifically designed to treat mold on walls. You can ask at the store where you buy wallpaper.
