WD-40® Multi-Use Product helps remove rust by breaking down the bonds between metal and rust. Spray the rusted surface with WD-40® Multi-Use Product, enough to thoroughly soak the area. Allow it sit for up to 10 minutes. Clean the rusted item with a wire brush. With the rust loosened, the brush should clean away most of the corrosion. Brush the surface until you’re satisfied you removed most of the rust and wipe any remaining residue. End by spraying with WD-40® Multi-Use Product to protect the surfaces from future rust.
