hi everyone, just printed off a tanning procedures listing from the forums on lutan. noticed it said to use 10% lutan f and 1% bascal s and 1% sodium formate also. what is sodium formate??? never seen it listed or added in anyones formulas for using lutan before. is something ready available under a different name perhaps.. This listing is sure conflusion as it states a formula 2 and 3 and no formula 1 on it. no mentions of pickling at all. any ideas out there??
