Avoid hairsprays with added perfumes, oils, or conditioners, as they can stain and damage clothing. Check the ingredients list on the bottle before using a hairspray. This will prevent the hairspray from drying out on the stain. Hold the hairspray about 2 inches (5 cm) from the stain while you're spraying. Make sure the stain is completely soaked with hairspray. Use a toothbrush for smaller stains. Check to see if the pen stain is gone before you put the garment in the dryer. If the stain is still there, apply more hairspray to the stain or try using a different stain remover.
