Hi all!!
i pretty much have all gardiners brushes, they are the only brushes i use now!! The white daul trim sill brush is spot on, great for both first and maintence cleans, the black soft daul trim is a good brush, good on maintence cleans only really, i use mainly on leaded glass. At the moment im torn between the white sill brush and the new daul trim with soft outer bristles and harder middle bristles, i prefer this brush but not as easy to clean sills. which ever on you go for its going to be great compared to a vikan sill brush!!
