I picked up 5 dryed not tanned muskrats in Alaska fur ronde I hydrated them in salt but I added some dawn to try and degrease them. I put them in a 2 gallon bucket with a gallon of safety acid. The ph jumped to 4 so I added more acid. After three days the skins were uneven so I took them out and rinsed them in water. I them put them in a new batch of acid. After three days I am still having uneven results. The PH has been at 1 and stable. Some areas are white and some are still grey. Some are red. (I assume it is blood I should have gotten off before the pickle) I am trying to add some pictures. I am still in Alaska and the nights are getting down to 55 or 56 so that may be impacting things. Any recommendation would be appreciated. I am continuing to stir them daily. When the pickle is finished, I will neutralize them and then put them in ez 100 to tan them.
