They call this linting meaning that small amount of fibers on the surface. On the paint its not a super big deal but on glass it is.Majority of microfiber towels I have shed fibers. Nothing worse than finishing washing car and finding these fibers. Do these towels shed? Assume good quality and do not scratch?
Best thing is buy good quality towels with stitched boarders. They last a long time so there is no reason to buy cheap
