Hi tradders! Some first floor windows, especially at the back of a family property, are very difficult to reach. Especially if there is a low roof extension in front of them, on which you can't climb. As a tradder you must then use some long pole (e.g. Lewi) to reach such awkward windows, and because you have to hold the long pole almost horizontally, the end of pole is so fiddly that you have no chance to precisely control a wagtail or any other squeegee. What you can do is to apply some hedgehog microfibre sleeve on the pole-mounted t-bar, but even if you spray de-ionised water on such sleeve, you end up (especially when doing the first clean) with ugly smears on the window panes. Has anyone tried some isopropyl alcohol based or containing solution to subsequently get rid of such smears?
