"Polishing steel

Aluminium foil is used to remove rust from steel and polishes steel surfaces by hand by rubbing it with aluminium foil dipped in water. The aluminium foil is softer than steel, and does not scratch the surface. Heat is generated by rubbing friction, the aluminium oxidizes to produce aluminium oxide. Aluminium has a higher reduction potential than iron, and therefore leaches oxygen atoms away from any rust on the steel surface. Aluminium oxide is harder than steel, and the microscopic grains of aluminium oxide produced create a fine metal polishing compound that smoothes the steel surface to a bright shine."

Anyone hear of that before?
