WD-40

WD-40 lubricates moving parts such as hinges, wheels, rollers,
chains, and gears. It protects against rust and corrosion on items like
tools, and sporting equipment. It penetrates to free stuck corroded
parts like nuts, bolts, valves and locks. It quickly removes adhesives,
corrosion and paint. It displaces moisture to restore water flooded
equipment such as engines, spark plugs and power tools.
