I was reading about the bypass filters cleaning the oil using toilet paper, and had rusty anti-freeze that was otherwise good.
I stuffed toilet paper into the neck of a large funnel and poured the anti freeze through. It came out much cleaner. I then packed in some fresh TP pretty tight and let it drip through overnight. It came out bright green.
Next I tried some mineral spirits that had sediments in it from cleaning parts. It stayed brown but had no sediments.
Toilet paper. It cleans everything.
