1. Prevent odor: keep ventilation when taking a shower to ensure that water vapor will not accumulate on the wall and in the air. At the same time, wipe it clean with a towel after each bath to prevent too much water from staying on the wall.
2. Use cleaning products: You can use some cleaning products specially used to clean the bathroom, such as multifunctional cleaning spray. These cleaning products can effectively remove dirt and odor, and also have disinfection effect.
3. Homemade cleaner: If you don't want to use chemical cleaner, you can choose to use homemade cleaner. For example, you can mix white vinegar with water, then spray it on the wall with a spray bottle and wipe it with a clean cloth.
4. Wall decoration: If the above methods can't effectively solve the problem, consider adding some decorations on the wall, such as wall stickers and wallpaper. These decorations can not only beautify your bathroom, but also cover up the smell.
In short, regular cleaning and ventilation is the key to solve the odor on the bathroom wall. If you take the above suggestions, you can definitely make your bathroom more fresh and comfortable.
