How to remove stains on white walls?

The methods to remove stains on white walls are eraser cleaning, white vinegar cleaning, bleach cleaning, hair dryer blowing, alcohol cleaning, and large-scale repainting of walls.

First, clean with an eraser.

For some small wall marks or footprints, we can use an eraser to remove them. But when cleaning, you need to pay attention to the strength of the eraser, and you can't use too much force, otherwise you will rub against the wall. If the dirt or footprints on the wall are serious, it is not suitable.

Second, wash with white vinegar.

It must be white vinegar, not ordinary vinegar. We mix white vinegar with water, put it in a watering can, spray it on the wall with a watering can, and then wipe it with a paper towel. This method is suitable for some dirty simple brushes on the wall. After waiting for 3-5 minutes, the handwriting on the wall will fade and be much cleaner than before.

Third, wash with bleach.

If you accidentally get coffee stains and other stains on the wall, clean them up in time, dry the water first, and then gently wipe them with a towel dipped in bleach, and the colored stains on the wall will slowly return to a white state.

Fourth, blow with a hair dryer.

If the children at home scribble on the wall with crayons, we can use a hair dryer to help clean it up. The substance in crayons will begin to soften and melt when it meets heat. We just take advantage of this feature, blow it on the wall with a hair dryer, add a little cream, and then wipe off the crayons with a rag.

5. Use alcohol for cleaning.

If the walls are moldy, consider using alcohol to help clean them. For mildewed, less serious situations, we wipe the wall with alcohol, and then gently brush it with a toothbrush. However, this method is still relatively easy to use for small mildew spots, but it is still difficult to deal with large areas.

Six, a large area of wall painting.

For large areas of stains, it is difficult to deal with, and we may need to repaint the walls to deal with them. If a large area is moldy, waterproof work should be done in advance, and then the wall should be painted.
