Ever get a greasy stain on clothes and worry that simply washing it in the washing machine won't do the job? One might think to grab laundry detergent and try to spot clean the stain, but don't: Most detergents are super concentrated and designed to work with water. They have very strong stain-fighting enzymes that, when applied directly to clothes, can create more damage and noticeable wear. Instead, reach for the best grease-cutting soap there is -- dish soap. It's gentle, works to break up stains and won't harm fabrics. Just spot treat, let it soak and wash in the washing machine.
