I put a deer hide and a coon into the pickle the day before Christmas, and because we were having family over that evening and the next day I put the barrel in the basement. The hides don't seem to be getting very white, though. They aren't a bloody pink, but more of a dirty brown color. The pH has been kept below 2. I checked the air temperature down there this morning and it's in the low 50's...I might know what my problem is now. My question is, can I bring the barrel back upstairs where it's warmer without doing anything more to the pickle solution, or do I need to add more salt and acid? The hides aren't ruined, are they? I haven't noticed any hair slippage.
