What should I do if the latex paint wall is dirty

Latex paint walls that are dirty can be solved by wiping with a damp cloth, cleaning with an eraser, applying toothpaste, cleaning with baking soda solution, and using professional cleaning agents.

1. Wipe with a damp cloth

Slight stains can be gently wiped with a wrung out damp cloth to avoid excessive moisture causing the wall to become damp. Suitable for common stains such as dust and fingerprints, wipe in the same direction to prevent water marks. If the stain is stubborn, it can be repeated, but excessive force should not damage the paint surface.

2. Eraser Cleaning

Dry stains such as pencil marks and crayon marks can be wiped directly with an eraser, maintaining even pressure during operation. This method causes minimal damage to the wall and is suitable for local small-scale cleaning. After completion, use a dry cloth to brush off the rubber shavings to avoid secondary pollution.

3. Toothpaste application

White toothpaste contains friction agents and can treat oil or tea stains. Squeeze toothpaste onto a soft cloth and circle to wipe the stain, then use a clean damp cloth to remove any residue. Pay attention to choosing regular white toothpaste and avoid products containing particles or pigments.

4. Baking soda solution

Stubborn stains can be mixed with baking soda and water in proportion to form a paste, dipped in a sponge, and gently wiped. Baking soda has weak alkalinity and can decompose oily dirt. After cleaning, it should be immediately wiped with clean water to prevent alkaline substances from corroding the paint surface.

5. Professional Cleaning Agent

Market specific wall cleaning agent is suitable for large areas of stains. Before use, it is necessary to test whether it will fade in an inconspicuous place. Dilute according to the instructions and handle with a soft bristled brush. After cleaning, ventilate and dry in a timely manner. Serious mold stains or chemical contamination require contacting professional personnel for handling.

Regularly use a feather duster to remove floating dust and avoid sharp objects scratching the wall. If liquid splashes, it should be immediately absorbed and oil stains should be treated promptly to prevent infiltration. If there is color difference after cleaning heavy stains, it is possible to consider local repainting. Maintaining indoor ventilation and dryness can extend the service life of latex paint walls, and a dehumidifier can be used to control humidity during the rainy season. For large-scale stains such as children's graffiti, it is recommended to contact a professional team to evaluate whether a complete renovation is needed.
