    Was wondering if anyone else had this issue... During the pickle process I've notice a few hides come out after 2 days with blackish areas (Spots) on the hide... I normally pull them from the pickle after 2 days and reshave before there last 24 hrs in the pickle. The pickle is maintain at about 65 degrees and ph between 1.5 and 2. Some shave out and some do not. The black spots normally come out during the tanning process or if I degrease them.. I use Rittles Safetee Acid as the pickle acid.. Any help would be greatly appreciated..
