Chimney brush types

Chimney brushes are the main tools used to clean chimney flues. When cleaning the flue you must use the right sized, and proper shaped tools for the job.

Brush material

Chimney brushes can be made of metal wire or polypropylene.rclma Depending on the type of chimney you have you will choose one of these 2 types of materials to use. Metal wire brushes are used for traditional masonry chimneys. It is ideal for removing the build-ups of creosote, soot and other byproducts. For chimneys with metal plating, you should opt for a flat wire bristle, which is harder than an usual one and much more effective in removing byproducts from the chimney.

Polypropylene or poly brushes for short, are used for liners, metal coated chimney or prefabricated masonry chimneys. These tend to become more fragile over time and that is why you need to use a poly brush. Poly brushes can be either regular type which is stiffer and doesn’t bend or prefab type which is more flexible than the regular type.

Brush size and shape

Some brushes can be custom made. The right brush for you must resemble the chimney. Choose the brush with the same shape as the chimney flue and the same size. The brush mustn’t be wider than 0.5 inches than the flue.
