i neutralized twice. this was due to me being like highly sensitive to the acid. i would not have thought that a low acid like that would have eaten me up but it did. so what i do now is pickle for 3 days, pull it out and drain, then neutralize, then dawn dishwashing liquid, this seems to really loosen that inner membrane and really plump the skin up to flesh again, then i rinse it off and put it back in the pickle. always buy A BUNCH of test stips, pool supply store or walmart, since the kits don't give you enough. i don't seem to have any ph issues and my skins don't slip, or at least they have not up to now. after i tan i break the crap out of them and put them in my wifes dryer with a bunch of tennis shoes, no heat. she doesn't like it but once i showed her that it would not hurt the dryer she was ok with it. kinda loud though!!!! everyone has their own secret recipe, this one works for me. basically, follow the directions on the package and the more you work with the pelt the better off it will be. the tanning 101 thread in the fur handling section is a great read also. i have only tanned 5 pelts so the others here have much more experience than i, but whatever works. this was a very good thread. thanx!
