I use ashes in a 5 gal bucket of water. I like the solution to feel "soapy" on my hand. I put in the deer hide, and leave it for 24 to 48 hours, depending. Stir/ shift the hide to make sure that all areas get exposed to the stuff. Cold /cooler temps take longer. Usually I can simply pull or even rub the hair off easily. If some areas are stubborn, I put the hide back in for another while. Once the hair is all off I rinse the hide well in water, then put it back in the bucket with a mix of water and vinegar for a 1/2 hour or so stirring once in a while. Then another couple of good rinses in clean water. Hope this helps
