How do you get hairspray off a shower door?

To remove hairspray from a shower door, start by spraying it with a mixture of equal parts vinegar and water, or a glass cleaner. Let it sit for a few minutes to loosen the residue, then use a soft cloth or sponge to gently scrub the area. Rinse the door thoroughly with warm water and wipe it dry to avoid streaks. For stubborn spots, a baking soda paste can also be effective.
