The Rust Removal Setup, on the left the variac for getting 12V at a high current, in the middle a AVO so as to tell the current voltage and on the right a pair of high power selenium rectifiers. Rust Removal Setup To do electrolosis rust removal first a container is filled with water and a little washing powder is added to make it conduct electricity. Once this is done the positive is connected to electrodes made of iron or steel around the object and the object connected to the negative. A voltage of about 12 volts is then applied, upto 25 works but at 20 after a few hours its steaming (NOT recommended) especially for plastic containers.
