I tanned a deer cape with lutan 2 days ago. I neutralised for 30 mins after the pickle and put the cape in to tan at a pH of 3.5-4. After I tanned it I washed it in cold water and let it drip dry and froze it. I tested the pH of the skin and it was at 4. Ive been thinking about acid rot and was wondering if I need to neutralise the cape more? It's been frozen for 2 days now. I'm just confused because the lutan instructions say to tan at a pH of 3.8, but then not to neutralise after the tan. So I'm assuming that it will be ok to be frozen still at that PH? I won't be ready for another few weeks to mount it. Should I thaw the cape and neutralise more and then freeze it again?
