Without window cleaning again clear view
Window cleaning is no fun, causes accidents at home and usually leaves streaks anyway!
Better just throw a brick through the opaque windows at a suitable place (best there, where you can optimally lense over to neighbor's). Then you have such a great view again, as if there were no disc in it, so clean!
P.S .: If the Scheibenklirren attracts the police, just claim the neighbor's boy was with his football. The new disc you get is clean too.
