Clean non-cleaned windows
Windows that have not seen a rag for more than two decades, because the room in question was only removed a few years ago, are cleaned with a glass ceramic field cleaner. Outside, they had been struck by the rain, as if it had not descended from the sky (without limescale) but from the faucet with limescale residue). The tip comes from our window supplier and helps.
Place the glass ceramic field cleaner on a damp cloth or sponge, wipe the disc completely (you do not have to play the muscles excessively), afterwards wet or wash it off with a puller, or wipe off a well wrung cloth and finally with a microfibre cloth , or who loves the leather rag, rub dry. Once a year the procedure is necessary again. In regularly cleaned windows, which have little roof overhang, it may happen that they also have partially dried drips; but that lasts longer.
