If you've been sprayed with or have inhaled pepper spray, you likely know just how strong and menacing it is. Causing eye tearing, trouble breathing and a host of other issues, pepper spray is often used for self-defense. When sprayed, it can reach other surfaces, such as walls, where it can linger and affect those who may breathe it. Clean off pepper spray from walls and other surfaces as soon as possible.
Pour cold water into a large bucket. Wipe the affected area with a water-soaked cloth.
Apply a non-oil based soap to the wall, such as dish detergent. Scrub the detergent into the wall with the cloth. As pepper spray is oil-based, using a product that contains oil will merely trap the oil into the wall, instead of removing it.
Dip the cloth into the water and wipe off the soap from the wall, after you have let it soak for 10 to 15 seconds. You may have to wash and rinse the affected spot several times, depending on how much spray was used and how deeply it penetrated into your wall.
