This cleaning cloth leaves a plurality of fine fluff / lint on the lens. Thus, if only to use along with a small blower or after a wash cycle, the problem could be resolved. One sees already in the product photo, the edge is serrated. This suggests large-scale production with rather poor quality, really good cleaning cloths have a sewn edge. Was I the purchase also clear, but in the amount of lint that remain on the lens, there are only 2 stars.
