When cleaning my windows with SCOTT® Towels and a solution of white vinegar and water, I keep a 2 inch soft bristled paint brush for getting in the hard to get spots of the sills and around the window frame. I use a little larger brush for brushing dust off the screens. I keep assorted sizes of paint brushes for dusting small crevices in furniture, picture frames and even the grates of my window fans. The brushes can be washed and used again.
