85% is good enough. Please see: More about lye http://journeytoforever.org/biodiesel_make2.html#lye >I'm a fan of the NaOH method because it leaves you with a byproduct >that can be used in waste fuel furnaces. Why do you think the by-product using KOH can't be used in the same way? If your waste oil furnace will burn NaOH by-product it will certainly burn KOH by-product. There are some glycerine by-product sawdust "logs" burning in our woodstove right now. Previously we used sawdust logs made with NaOH by-peroduct, there's no difference.
