Step 1
Scrape as much of the ChapStick off the wall as you can with a plastic butter knife. Scrape at the stain gently to avoid removing paint from the wall or tearing the wallpaper.
Step 2
Dampen, but do not soak, a clean rag with water. Sprinkle half a teaspoon each of powder laundry detergent and baking soda on the rag. Rub the rag together with your hands to blend the mixture.
Step 3
Rub the rag slowly in a circular motion over the affected area. Be as gentle as possible to avoid removing paint or injuring wallpaper.
Step 4
Apply a dry cleaning solvent to the stain if the baking soda/detergent mixture has not fully removed it. Gently rub the stain in a circular motion to avoid upsetting wall paint or wallpaper. Do this until the stain has disappeared.
