Naval Jelly® Rust Dissolver
[Loctite] A registered trademark for a commercial rust remover. Naval Jelly® contains water (65-70%), phosphoric acid (25-30%) and sulfuric acid (1-3%) in a gel matrix composed of a thixotropic polysaccharide (1-3%), isopropanol (1-3%), surfactant (1-3%) and silica (0.1-1%). The phosphoric acid dissolves the rust (iron oxide) and then reacts to form iron phosphate. The iron phosphate provides a thin protective coating to minimize further oxidation. For treatment with Naval Jelly® , the pink gel is brushed on the metal surface, allowed to stay for 5-20 minutes, then rinsed off. The acids are then neutralized with a baking soda paste. In addition to removing rust, Naval Jelly® is used to prepare iron and steel surfaces for painting.
