Well, here is my ? I just bought a bottle of Krowtann and was looking the instructions over so I would know how to use it the next time I do a deer. Right now I have a deer in the pickle using directions that came with McKenzie tan. I plan to finish this cape using the McKenzie tan, but I noticed on the Krowtann bottle that it said to use sodium bicarbonate (???) (I can't remember the whole name right now). It also said you could use baking soda to neutralize, but if you did use baking soda, to use twice as much, compared to using the sodium bicarbonate. So, do I need to use twice as much baking soda when I go to neutralize my cape out of the pickle too? I guess what I am asking is, does that rule apply to neutralizing anything--to use twice as much baking soda as you would sodium bicarbonate when you go to neutralize? I will be neutralizing and tanning this evening sometime, so any help would be appreciated!
