i normally use my extreme wide with fan jets for everything, but i was doing a first clean the other day on a really dirty frame and the extreme wide wouldnt touch it, but i put a vikan on and it came off very easy, (it is the green and red flcoked one i think) so am thinking of getting a new brush i want something that is as light a extreme wide but with a good cleaning power as the vikan, what do people suggest, as i was looking at the new sill brush from gardiner but dont know when it will actually be out, i also want it for every day use,
