Sturdy and dependable, metal shelves are a must in your garage or shop. Unlike wood shelves, metal shelves can withstand the weather and the cold environment leaving you to think that these shelves are impervious to everything--until you notice the red spot forming and realize that rust is setting in. When water and iron come together, rust is formed leaving a reddish color behind, and eventually eats through the metal altogether. If you can catch rust early, removing it is a simple chore that helps keep your shelf a sturdy and dependable structure.
Brush away loose rust particles with a fine grit piece of sand paper.
Sprinkle coarse salt over the rusted area.
Mix lemon juice and white vinegar in equal parts and pour it over the salt.
Allow the solution to sit on the rusted area for five to seven minutes.
Wipe away the solution with a dry towel and rinse the area with water.
Dry the area with a dry towel again to remove the excess moisture.
