Has anyone used oil burnt smelly tranny fluid to clean the piping of the centrifuge?? The lines do get a little gunky from the dirty oil run through. Or do you use something differant, short of taking all the piping apart??

I've run somewhere around 6000 gallons through mine and have never seen a need to clean any lines.

I see no need to clean the lines after >3 years. Mine aren't gunky at all, when not in use the lines all stay full of VO from the previous batch. and the valves are closed. Poly gunk needs air exposure to form.
