<x-charset ISO-8859-1>Hellow Keith, Yup. Sometimes biodiesel clouds right back up after it's cooled down. Used to see this when we "sun dried" fuel. Every time the sun went down the fuel clouded back up.
I have a feeling that it quickly absorbed as much water from the cooler air upon sunset as it dispersed in the heat of the day. Seems that the elevated heat tends to drive much of the moisture into the ambient air if done in a well vented tank or container. A little bit settles out, but more of the former.

Some people do 60 deg C (140 F), but I agree with Todd: > "Approximately 120*F (~46*C) is more than sufficient."
