How do you guys get by without a whole bunch of wire wheels? Here in the rustbelt I must use one for something almost daily and have a whole assortment. My go to is the bench grinder from HF which only has enough guts to run wire wheels anyways. Then there is the 4.5" disk and cup that are on the grinders for the hard to get at stuff which most of it is. No guards whatsoever here, all they do is get in the way constantly. I do make sure the face shield is on and with the angle grinders muffs. Keep that chin tucked down so the shield protects the soft places and wear gloves, then let the crud fly. FYI I being a cheap *&^%^ use Forney brushes and disks. They last 3/4 as long as the Makitas and cost about half. Tiny 1" jewlers brushes on my Dremel are the absolute go to for cleaning crevices and especially corroded electrical terminals. Stay away from the Dremel $5 ones, they self destruct as fast as the cheap $21 for a 20 brush bag I get from some on line store on Eabay . You have to handle them gently but oh do they get in the small spots nicely. If its soft stuff I just use the soft wheel. Usually I clean all rusty bolts I have to pull this way as it makes them easier to install and hopefully easier to pull next time. Some Neversieze compound helps too.
I don't doubt that evaporust works well but I bet it works a lot better and lasts a whole lot longer if you knock most of the crusty nasty stuff off first with a wheel and use it only for the pits and crevices. I hadn't seen that around but the price makes it definitely worth looking into. I assume it's some other form of Phosphoric Acid which I already use. I will be looking that up. Do you have to soak or does it work to some extent on things large like panels?
