SteelBlue, I would never use my micro fiber towels on dirty wheels, for the exact reason of your question. MF towels I consider to be "finesse'" towels. These towels should only be used for glass, QD spray, or for removing wax, polish sealant. I don't use them for early stages of detailing, for the simple reason early on you are still removing dirt and other contaminants. Once the fibers pick up these foreign dirt particles they can be difficult to remove over time. You want these towels in top condition for your final phases of detailing. always wash them separatly from your other towels. Gary
