The almost ethusiastischen reviews, I can not agree to a limited extent. As described on the instructions I have the cloth thoroughly washed first and hung up to dry. After complete drying it has been lightly dusted. However, the use of the inside of the windows was sobering. Although the slight dirt went away entirely, but by no streaking was not the track to see. On the contrary, they saw each "wiper" quite clearly. So I had rather not imagined by the preliminary reports here. To wet the cloth can be frankly not have been, because it was only slightly angestäubt. At least I understand this level of "moisture" under anstäuben. In principle, a breath of nothingness of water. It was only when the cloth was dry and it worked again the bodies which streaks were reasonably away, but this is associated with significant overtime because a dry cloth to dry glass migrates already rather "rubbelig" over the glass surface. I am excited about what the next attempts to bring so. If the power in the way to go, I cross back to normal disc cleaning methods with clear window and paper towel. The workload remains the same total, if you always have to wipe the Alcleartuch after drying.
