Just experimenting with 2% ammonium chloride right now. Instead of boiling in distilled water, steaming regular water does the same for long parts. I have a rusted shotgun action and barrel I will try the steaming with.Care to tell us about it, how it works, what solution you use in it, ect....
I will post pictures. I have a Stevens 67 that is covered with rust that I will try converting and carding to see how it turns out. The funny thing about the rusty Stevens is the bore looks like a mirror.Interesting!
It does not steam off the rust but converts it to black rust (ferro-ferric oxide) that leaves a layer of black rust fuzz that can be steel wooled off (0000) or carded with a very fine wire wheel and basically how guns were blued before hot dip bluing which is quicker and better suited to production. Rust bluing takes more time. What I am trying is called conservation and stops it from rusting more. I will see after that how pitted it is.Definitely would love to see how that turns out. I've never heard of steaming the rust off.
That’s fine depending what one plans on doing. Converting rust to black rust is just a non-invasive way to convert rust to bluing instead of removing it and rebluing it. For old firearms you are not going to refinish it’s the way to go for preservation. I will do this eventually with my Civil War guns but will not refinish them.Why isn't anyone using evaporust stuff or even something that works amazingly...electrolysis?
Same temperature but no need for distilled water. I have a cheap deep fat fryer for boiling small parts in water.I read something about boiling ferrous metals some years ago, hadn't heard about steaming.
Trying with some steel blanks to see if I can blue them. I am using a 2% ammonium chloride solution to start with. The rusty gun will get a steaming no matter what.I'm following with great interest!
