Got a rusty stain on white socks? Use WD-40. Spray it on the stain. Wait ten minutes. Rub with a toothbrush.
WD-40 smells like a mechanic’s garage. But it literally pushes the rust away. Rinse with dish soap to remove the oil. Weird, right?
Another wild card: hydrogen peroxide. Blot it on the stain. Watch it bubble and lift oxidation. It works best on fresh rust, not ancient history.
