Acid rust removal agent, as the name suggests, of course, is to use the common strong acid (sulfuric acid, hydrochloric acid, nitric acid, etc.) for rust removal. Its principle is to use the oxidation and corrosion of acid metal oxides, corrosion dissolved to achieve the purpose of rust removal.
Neutral rust remover, namely the PH value between 6.5 and 7.5, is called neutral, its rust removal principle is only with the metal surface of the oxide: iron oxide and iron dioxide reaction, not reaction with iron atoms. So as to be safe and accurate removal of rust.
Ruust converter rust converter working principle is to let the converter in contact with the rust layer, the chemical reaction occurs, and eventually will form a layer of black anti-rust paint layer. This method will change the metal state and the paint will off easily.
