I have a self cleaning glass conny roof to clean. It's a 'P' shape, so there is a gap from top to bottom where the 2 roofs meet. In the gap is moss and leaves. There is no outside tap, so I can't blast the muck out. The gap is too small to get a brush in to drag it out. It needs something very narrow to get in there and be able to pull/drag it all out. I need to adapt something to fit on the end of my pole. What could I use? I'm thinking I use just a brush socket on the end of an angle adapter on the pole and use the thin edges to get in there. Can anyone think of a better idea?
