I recently lost 2 deer hides during the pickle. I switched to Saf-tee acid and so far have pickled and tanned 2 racoons, 1 red fox and 1 deer cape without any problems. The 2 deer hides did not make it, they both slipped during the pickle. I start fresh every time. I do not reuse my pickle. I had a really hard time keeping the PH stable during the pickle on the 2 hides. I followed the instructions to a T. I can't figure out how the other hides turned out fine and not these two. Does the pickle have to be at a certain temperature? I do this in my mud room in the basement. It is usually 50-60 in there depending on the weather outside. Any suggestions or help will be greatly appreciated. Thanks to all who reply.
