How does one clean a wall?

There are several ways to clean a wall, and the best method will depend on the type of wall and the type of dirt or stain that needs to be removed. Here are a few general tips for cleaning walls:

1. Start by dusting the wall with a microfiber cloth or a soft-bristled brush to remove any loose dirt or cobwebs.
2. If the wall is particularly dirty or greasy, you may need to use a mild detergent solution to help loosen the dirt. To make the solution, mix a small amount of mild dish soap with warm water.
3. Wipe the wall with the detergent solution, using a soft cloth or sponge. Be sure to rinse the cloth or sponge frequently to prevent spreading dirt around.
4. For tougher stains or marks, you may need to use a small amount of a mild abrasive cleaner, such as baking soda or white vinegar. Be sure to test the cleaner in an inconspicuous spot before applying it to the entire wall, as some cleaners can damage paint or wallpaper.
5. Rinse the wall thoroughly with clean water to remove any remaining dirt or cleaner.
6. Allow the wall to dry completely before painting or applying wallpaper.
