While a few of the metal rust removing products on the market are designated as natural products, the most effective rust removing metal cleaning products are made from some kind of chemical compound of a low-level hazardous nature, such as a low dose of phosphoric acid. Conversely, Colonel Brassy metal cleaner made from the following:
Citric Acid 4.5%
Stearoamphoacetate 12%

Diatomaceous Earth 24%
Water/Inerts 41.5%

The chemical solution in Colonel Brassy react to the rust or oxidation of the metal and convert it into a combination that can be easily rubbed off with a cloth.

Depending on the metal and the severity of the rust only a small amount of Colonel Brassy will do. Too much application of Colonel Brassy metal cleaner can give rise to an abrasive result
