Commercial - How it Works


For rust to form, there needs free-electrons, moisture and oxygen present. If any of these are missing, rust cannot form. The free-electrons are negatively charged, so the strong positive charge on the Anodes cause an attraction of negative free-electrons away from the vehicle and the anodes now corrode rather than the vehicle. This reduces the rusting process on the vehicle.


Any steel contains millions of free-electrons which are negatively charged and move around in the metal due to positive and negative charge differences caused mainly by impurities in the steel.

These small charge differences (normally around 1 volt) act almost like a magnet, and so the negative free-electrons are attracted toward and accumulate at the positive points.


When these free-electrons are exposed to oxygen and moisture, a reaction occurs, and they are lost from the steel. This reaction is known as oxidation or RUST. 

RustStop® RS-5 outputs a positive charge onto the Anodes, approximately 50 times greater than that between the impurity and iron atoms. The iron and impurity atoms are now effectively all negatively charged in relation to the strong positive charge on the Anodes and so the free-electrons are attracted toward the Anodes.
