Step 1: If your walls are dirty, use a little dish soap mixed with water to gently clean the walls. Be sure to thoroughly squeeze any excess liquid from the cloth so as not to create more stains.
Step 2: Mix one part bleach with two parts water.
Step 3: Warning! Before you start wiping down a whole area, be sure to test a small spot that’s not in plain view.
Step 4: Be careful not to apply too much water; you want the stain to disappear, not get worse. After applying the solution, dab with a dry cloth to prevent further staining.
Step 5: Let the bleach solution rest for 5 minutes, then “rinse” or blot again with a wetted rag. Allow your paper to dry thoroughly before applying a second coat on any stubborn stains.
