How to Remove Rust From a Metal Lawn Table

Rust forms on metal when water sits on the surface for a long period of time. The water combined with oxygen deteriorate the metal forming rust stains. Items such as metal lawn tables form rust spots when left in the rain and leaving the water to evaporate on the metal surface. Not removing the rust spots allow them to spread over the entire metal surface, permanently damaging the table. Remove rust spots as soon as they develop to save the furniture from needing replaced.
