I have been using Unibath in a stainless steel salad bar tub about of 1/3rd of a tank for forend irons, trigger guards and other smalls. It likes to work best at about a 275F slow rolling boil. I like it because it has a nice deep black, only need one heated tank and is not picky about cleanliness . Polish the part wipe off with a rag dampened with Denatured alcohol drop in tank till happy with color and dunk in cool clear water then oil. Unfortunately Unibath is no more and I will eventually need a replacement. It's the only hot salt solution I have experience with.Is something comparable out there?
