The reflective quality of the window doesnt help. However the first pic is a window which the birds have used as a target when they relief themselves,,,,,with so much hype about vision or other additives to put in my pure water, i cant believe my eyes!! Iv somehow been able to clean the mess off and the window looks sparkly clean,,,,,,,but how can this be with just pure water??? Lol, haha.
Sorry couldnt resist
