as far as what it does to a skin. I had always used pickling crystals and just tried safety acid after hearing the raves about it on here. The Ph of the pickle was way lower and stayed low, but the cape came out of the pickle feeling much firmer and tougher. So much so that it was a lot harder to do the final fleshing and shaving. I use a mini flesher and razor blades. Are the pickling crystals better suited to use with them? Or should I change something up on my mixture. I do about a 40% salt solution in the pickle and about 1/2 oz of safety acid per gal (maybe a little more actually). I also now realize from reading some previous posts that I didn't neutralize it enough either.
