The weird substance started to trail up the sides of the beaker and rise to the surface. there they somewhat clumped together into a weird goo. I scraped off this goo (think skim milk), and carefully poured the "dirty oil" into another beaker. This beaker was then placed in the same position as the previous (on a hotplate with a stirrer at 130c, 500rpm). Next you wait to see if anything else seems to rise to the surface, if not then you should be good to go. Warning- it is a bitch to clean the substance from the first beaker, you may want to use a steel pad.

An aqueous NaOH solution should make short work of removing the deposits.
