Very interesting and convincing examples shown here. Wondering if anyone uses this stuff on rusty parts that are too large or bulky to submerge in the solution? In such a case can it be sprayed on then rinsed off with a water hose? I’m thinking automotive use like if a differential housing has slight surface rust on the black paint, would this remove it then dry and repaint?
I have also read that acetone can act as an effective rust remover, maybe it’s an ingredient of evaporust which is why it flashes off quickly?
