Hairspray does an admirable job of keeping your tresses in place, but it's a nuisance when it adheres to objects such as mirrors and picture glass during application. Once the hairspray dries on an object, you can't wipe it away easily with a wet cloth because it will smear and leave an unsightly residue. Instead, you will have to turn to the power of a solvent that will cut through the hairspray and restore your mirror or glass back to its original gleaming appearance.
Pour 1 tbsp of rubbing alcohol into a small container. Dip one side of a clean cotton ball into the solvent.
Rub the alcohol-soaked cotton ball on the affected area of the mirror or glass to power away the stains.
Wipe the glass or mirror with a clean, lint-free towel to remove any alcohol residue.
Check the surface for cleanliness and repeat Steps 1 to 3 if needed.
Step away from pictures, windows and mirrors when spraying your hair. Check your hair in the mirror after spraying. This will help keep hairspray staining on mirrors and glass to a minimum.
