Your favorite baking pans and cookie sheets always seem to be the ones that collect the most rust. Tin is a soft, crystalline metal that is silvery white when not rusted. You can readily restore rusty tin to its natural luster.
Rub the rust with super-fine steel wool. Rinse with warm soap and water should do the trick.
Rub the rust with a peeled potato dipped in baking soda or salt.
Soak the tin in container containing a cola drink. Soak and then let dry. Rub off the rust.
Rub rusty tools with a soap-filled steel wool pad dipped in kerosene or turpentine. Follow by rubbing with wadded aluminum foil on the tools.
