You can remove rust corrosion from metal objects without damaging the surface. This expert-recommended DIY method calls for vinegar, salt, and baking soda.
Wrought iron. Rust is an iron oxide, a usually reddish-brown oxide formed by the reaction of iron and oxygen in the catalytic presence of water or air moisture. Rust consists of hydrous iron (III) oxides (Fe 2 O 3 ·nH 2 O) and iron (III) oxide-hydroxide (FeO (OH), Fe (OH) 3), and is typically associated with the corrosion of refined iron.
Often, it is possible to chemically remove the products of corrosion. For example, phosphoric acid in the form of naval jelly is often applied to ferrous tools or surfaces to remove rust. Corrosion removal should not be confused with electropolishing, which removes some layers of the underlying metal to make a smooth surface. For example ...
Rust, which is primarily composed of iron oxides (Fe₂O₃), also reacts with weak acids to form soluble iron salts. The reaction can be simplified as: Fe2O3+6H+→2Fe3++3H2O In this process, iron ions (Fe3+) are produced along with water, making the rust easier to remove without causing damage to the underlying metal or surrounding materials..

Rustproofing is the prevention or delay of rusting of iron and steel objects, or the permanent protection against corrosion. Typically, the protection is achieved by a process of surface finishing or treatment. Depending on mechanical wear or environmental conditions, the degradation may not be stopped completely, unless the process is ...
