Soap cleans. It is ok to use cooking pots, pans, stirrers etc for soap making. The lye, sodium hydroxide, is water soluble, and also washes out, no problem. Use stainless steel pots etc.
I will send you our aproximations on lye, fat etc later. I am on my way out the door, will do so when I get back.
Thanks!
What else can one quanties of clean rendered fats for, other than soap????
