I thought Sidolin was good. Unfortunately this is not so, at least not with my glasses. I always have a veil on the glasses. The best experience with glasses cloths I have so far been given house brand with the DM-market or by Blümli. Alternatively, you can also take Handwaschgel of DM market, making the front and back of a spectacle tropical, run lukewarm water over it until it's all gone and upward blow just once, dab with paper towel, ready. Only works optimally with glasses made of plastic.
