Difference between neutral rust remover and acid rust remover in rust removal principle: 

Rust removal principle of neutral rust remover: by chelation reaction, it only reacts with oxidized iron monoxide and iron dioxide, but does not react with iron atoms, so it can accurately capture oxides and decompose them, but does not work on unoxidized iron metal. This rust remover can strictly control the amount of rust removal, so as to accurately remove the oxidized parts without damaging the unoxidized parts. 

 Rust removal principle of acid rust remover: It uses the principle of acid corrosion to dissolve the rusty surface, so as to achieve the rust removal effect. The acid rust remover dissolves and peels off the rust layer and impurities, in which a variety of raw materials are adsorbed on the metal surface to form a diffused electric double layer on the solid-liquid interface, and the rust layer, impurities and oxide layer are peeled off by using the repulsion effect of the same charges on the rust layer and the metal surface. 

 Difference between neutral rust remover and acid rust remover on metal layer loss: 

 Because the neutral rust remover only reacts with the oxide, the metal layer is not corroded and lost. No Matt that contact time of the rust remover and the metal lay is long or short, and no matter the concentration of the rust remover is high or low, the metal layer is not corrode. Therefore, neutral rust remover is called safe rust remover. 

 The acid corrosion principle of acid rust remover not only acts on oxides, but also corrodes the surrounding metal and accessories, so it is necessary to strictly control the operation steps and time to avoid excessive damage to the metal surface. 

 Difference between neutral rust remover and acid rust remover on the safety of plastic and rubber accessories: 

 The neutral rust remove is neutral in solvent, is not corrosive to plastics and rub, and does not produce corrosive or harmful substances in that reaction process, so that the neutral rust remove can be safe and undamaged even if the neutral rust remover is treated together with plastic and rubber accessories. 

 Acidic rust remover itself is strong acid or weak acid, which is seriously corrosive to plastic and rubber products and should not be used in contact with them. ++ Difference between neutral rust remover and acid rust remover: 

Both neutral rust remover and acid rust remover can be used to remove rust by soaking, brushing, spraying, etc. The difference is that the neutral rust remover generally does not need to control the soaking time, while the acid rust remover can not be soaked for more than the required time, otherwise the metal will be corroded. 

 Difference between neutral rust remover and acid rust remover after rust removal: 

 Neutral rust remover after rust removal: because there is no damage to the metal layer, and the use of a special formula of neutral rust remover, the metal surface can be slightly passivated, thus providing several weeks of rust protection. 

After rust removal by acid rust remover: due to the metal rust itself causes certain damage to the metal layer, the surface of the metal layer loses the protection of the passivation layer, coupled with the corrosive effect of acid rust remover, the metal layer is actually full of holes. Some of them even return to rust quickly in a few minutes after treatment, and the degree of rust is worse than that before rust removal. Therefore, the use of acid rust remover needs to be combined with rust inhibitor. 

Difference between neutral rust remover and acid rust remover after rust removal: 

Rust removal speed of acid rust remover is 3-15min 

The derusting speed of neutral rust remover is 6-24 hours 

The derusting speed of ENIENT fast neutral rust remover is 3 ~ 5 minutes 

ENIENT fast neutral rust remover has more excellent performance in terms of rust removal speed, safety, operation convenience and rust prevention.
