Ooops, a drop of salad dressing landed on your favorite shirt. The fix? Simply squirt clear shampoo on the spot. Gently rub it in, then rinse with the hottest tap water the fabric will allow. I have read that the alcohol-derived detergents in shampoo are designed to cut through sebum, the naturally occurring oil that coats our hair. And because it gets rid of oil, it’ll also effortlessly lift stubborn oil stains on your garments without damaging it.
