I tested this on WVO that would not clear up with heat. The issue was not the water but the large amount of small particles that hold the water.
After I added the salt and let sit for 20 hours the all the small particles were on the bottom and the oil was clear.
I am working on my first 55 gal. drum of WVO that I filtered with 15 micron and moved it to a 55 gal. drum with some salt and baking soda. I plan to let that sit for some time....weeks, then filter 1 micron to final drum and heat, cool, pump from top leaving bottom 1/3.
I have read on Greasecar site that the salt and bs do work.
