Try a Magic Eraser if you don’t have stain remover on hand. [3] X Research source Test the cleaning product on your walls before you apply it to the stain. If you have a painted wall, it might wear off some of the paint. Rub a little bit onto a less noticeable part of the wall, like the baseboard, to check.
Repeat this process as needed.
If you don’t have a cleaning brush on hand, consider using a toothbrush instead. To pack an extra cleaning punch, consider using a dish detergent with a citrus base. [7] X Research source
Scrub a smaller, lower part of your wall with the detergent before rubbing it around a larger area. If your wall is painted, you don’t want to accidentally remove any of the paint in the process.
If your stain is on a higher part of the wall, consider using a sander with an extension to rub it down. Aim for your sandpaper to be 120 grit or higher. [11] X Research source
If you aren’t sure, check the label on your primer can to see how long it takes the product to dry. Use the same grit sandpaper as you did before.
Certain brushes are better for certain types of paints. If your paint is oil-based, use a brush with natural bristles. If it’s water or latex-based, opt for a synthetic brush. [15] X Research source Feel free to use any leftover house paint you have on hand.
