A heavy duty of hair spray may result in some of it end up on that timber dresser or vanity near the mirror. If left to dry in place, hair spray leaves spots on the timber and may become more difficult to eliminate as time goes on, potentially damaging the end or attracting dirt while the spray is still sticky.
Rub it Away
Put some rubbing alcohol on a lint-free fabric, such as microfiber, then wipe it over the affected wood. After having a damp cloth removes any remaining residue. After that, dry it off with the other a lint-free fabric.
Shampoo to the Rescue
Shampoo also works to remove hairspray from timber furniture. Pour a small amount on a damp cloth, then rub it over the affected regions. Wipe clean with the other damp cloth. If the hairspray is particularly stubborn, rub a baking soda non-gel toothpaste above the area with a toothbrush, then cleaning up the place with a damp sponge afterwards. Dry the furniture with a soft fabric.
