Vinegar’s back! This inexpensive miracle worker gives brighter, cleaner, fresher laundry. For instance, it removes sweat and deodorant stains, replaces fabric softener to reduce static, and boosts detergent power while eliminating buildup from powdered cleaners. An overnight soak in half and half vinegar and water can help kill stubborn workout smells. Add a half cup to your next load and see the difference.
