best rags for assembly

there's regular bath towels cut up & blue shop paper rags & I saw something about microfiber rags & there was something about one of ems fibers wont dissolve in oil (iirc) so are bad. educate me please. thank you for your time. RR
I've always used cloth baby diapers, they are lint free, absorbent and washable making them 100% reusable. I've never used any towels made from paper. I can't say anything about the blue ones as I've never used them before.
