Or any acid solution, for that matter. It seems to work quicker, requires less, and doesn't reintroduce a bunch of stuff that you DON'T want in the fuel.

Of course, it's not quite as "available" as glycerin, I'll give you that.

I bought a gallon of White vinger, it worked great I used less than a quart to breake the emulsion in my wash tank, thanks for the tip

If using acid to break an emulsion when washing biodiesel, remember that the action of the acid is to turn any soaps into Free Fatty Acids.

I do not make biodiesel, I prefer to use the oils (including FFA) as my fuel, in my 2 tank UCO conversion.

So if the action is to turn soaps into FFA, would it be wise to retransterfy the mix? I understand that FFA's are bad for injectors and pumps, so what would one do to insure that they were eliminated or converted? Would they be caught in subsequent washes?

if you retransesterify you're just making soap again, and it's hard to control the reprocess to keep from making even 'more' soap.

also, FFA does not wash out. INdustrially, in various other kinds of vegetable oil chemical processes, I think they take care of the FFA by making soap with them by neutralising with lye- so you've got either FFA in your fuel or soap to wash out, and not making the FFA in the first place is a lot easier.

hey I'm just getting started in this bio stuff and i'm wondering if any body has a good recipe without the use of methanol and what is the vinigar used for. Any recipe's that you have would be greatly appreciated.
