Clean the windows with vinegar
Did that with the vinegar, it works. Unfortunately, I am 100% handicapped. Therefore, window cleaning with a cloth and ladder is flat.
That's why I bought a puller with extension and a microfibre cloth. Unfortunately there are stripes.
That's why I read the tips here. In a commentary - which I can no longer find - was, "on the puller water and vinegar". I tried that, without peeling or drying, because of my disability.
I just take this microfiber cloth, keep it under cold water, then pour it over vinegar. The windows are only wet with it. They are not dried. It dries streak-free.
Because of my disability, I can not stand long, I have to go on the rollator. Cleaning windows was a horror for me. Of course, everyone has their own method of getting streak-free windows. This works for me.
