Part 2 A final test is to put it in the fridge and see if the biodiesel remains bright and clear as it cools further. If it clouds this is probably a sign of moisture that requires further removal. If it clouds and starts to go solid you have reached it's gel temp and has nothing to do with moisture. Good luck
Hello Tony, I'll just make a note of that litre in my royalties book. The quickest way to dry your litre of water washed biodiesel is to pour it in a small pan and heat to around 100deg C while continually stirring. I use the thermometer to stir. It will probably turn crystal clear. Let it cool After the biodiesel cools there is likely to be some water in the bottom of the container and the biodiesel might have turned cloudy again. Pour just the biodiesel only into another container and again heat to 100deg C while stirring. If it does not pop or spit as it heats to 100deg C or a bit past and all you can see is heat convection currents rising from the bottom of the pan with no settle out then I consider it to be dry enough.
