I bought a gallon of Iosso and attempted to clean about 70 lbs of 9mm brass. I left it in the solution for about 1 minute and the brass started to shine right away so I would take it out and put it in a 5 gallon bucket of fresh water the repeat for the next batch. So far so good until it dried and now is a very dark color and the inside of the case is not as clean as I like. I'm running them through my tumbler which is knocking off some of the tarnish but still discolored.
Any experience out there with Iosso?
