Add liquid dish soap to water. Wash the stain in a circular motion using a soft cloth or sponge and rinse. If stain remains, repeat the procedure. Fresh marks are most easily removed. Residual stains on white walls and more durable surfaces may be removed with Soft Scrub, toothpaste or a mild abrasive cleanser. Apply cleanser with a soft cloth or sponge. Work the stain for several minutes. Rinse with water. Repeat if necessary.Special Precautions:Only use non-abrasive cleaners such as liquid laundry detergent, Scratch Guard or Parsons Pine Scent Ammonia on colored painted walls and surfaces to remove stains. Do not leave cleaner on surfaces for an extended period of time.Special Note:Due to differences in formulation among various paint and soap manufacturers, a cleanser may work differently on one paint than another. Colored flat paints are more sensitive. Very slight residual stains may fade with time.
