Sad but simple truth, there is nothing that beats Chamois leather when it comes to the finishing of cleaning glass and other shiny surfaces such as car bodywork. A Chamois is super absorbent; naturally lint free, easy to wring out and simple to wash out when done with. This one is a full skin so is of slightly irregular shape but is 3.5sq ft in overall size, a good large one that has been pre-oiled to ensure it is supple. In the words of the song 'Simply the best'.
