Ok guess I should clarify a bit. I pickup my oil from a couple spots, and its decent but always has stuff floating in it. So as it goes into the storage tote I poured it through a 100 mic bag filter that's about 14 inches long. The raw oil sits in the tote till I need to make a batch.
Then from the storage tote I pump to my processor.

I just got thinking about trying to use magnesol, and everyone on here seems to be filtering the mag in a 3 part filter setup. Everyones mic ratings seem to differ a bit, yet I'm only trying to figure out the proper ways of cleaning a filter bag. Whether its wvo or magnesol on the bag how should they be cleaned? to
