The instructions with all the chemicals I’ve been using for the last few years from Van Dykes talk about using bicarbonate at 1 oz per gallon to neutralize after the pickle. It says the optimal ph for hides to tan is 4-5 My natural water is 7. Should I not use any bicarbonate? I’m thinking when I put the hide in straight tap water it will end up closer to 4-5. Is there a more precise way to do this? Should I try it with straight water and then test the ph after 20 minutes to see where it’s at? It says over neutralizing is very bad so I don’t want to mess it up but I’m not sure how to make sure it’s right. Water ph varies so that recipe of 1oz per talon can’t be good for everyone?
