PB Blaster breaks free rusted or frozen parts including nuts, bolts, and pipe threads. As an added bonus, PB does not evaporate, it leaves a lubricating film on parts to protect against further rust and corrosion. PB is the #1 selling penetrant on the market and is designed to attack rust from all angles using a unique capillary action.
