Wall cleaning should be performed according to the material (such as latex paint or wallpaper), and you must test it in a concealed area before cleaning. Methods include using a white eraser to remove pencil marks, gently pressing with a slightly damp cloth to remove stains, etc. Absolutely avoid vigorous scrubbing or excessive moisture to prevent paint from peeling off.
Judging and testing wall materials
Different coatings react differently to cleaning agents and moisture. Before you start, be sure to test in a concealed area to see if the cleaning agent causes discoloration or peeling.
- Latex paint: Usually wash-resistant; you can use a slightly damp cloth to gently pat away stains, avoiding excessive friction.
- Wallpaper: You need to first determine whether it has a waterproof coating; water should absolutely not be used on paper wallpaper.
- Concealed test: Test in a corner of the wall or behind furniture, and only proceed with cleaning after confirming there is no color difference or material damage.
Stain-specific treatment methods
The key to handling wall stains lies in using "gentle force" rather than brute force.

- Oil stains: Use a tiny amount of dish soap solution, dip a cloth in it, wring it out, gently press on the stained area to dissolve the oil, and immediately wipe clean with a cloth dampened with clear water.
- Mold spots: Use diluted bleach (the ratio must follow the official recommendation), gently pat away with a cloth, and after treatment, you must use a dehumidifier or fan to completely dry the wall.
- Crayon marks: Use the hot air from a hair dryer to gently blow and soften the wax, then use a paper towel to absorb the surface layer.
