there are DEFINITELY different qualities of microfiber, but I think most, if not all, are made from Poly. You can usually tell the really cheap ones from the **** imprint that is permanently molded into it. These are garbage. Then again, I hate almost all microfiber. Use a booster and a buffer, if you op guys have that, to remove the oils which oxidize into polys. A booster is an oxidizer, like "boost all" from bridgepoint, but I understand you guys have one for op. Good luck.
