Many families now equip their chimneys with a 7 inch chimney cleaning brush, but since there is no standard chimney, the internal dimensions of the chimney must be measured before determining the size and type of the brush. For metal or prefabricated chimneys, you need to remove the chimney cap and then measure the distance to the inner diameter of the chimney. For masonry chimneys, it is necessary to measure the dimensions of the inner flue lining in two directions.

For metal or prefabricated chimneys, you need to choose a 7 inch chimney cleaning brush with the same diameter as the round brush. PE brushes are recommended for metal chimneys because they will not scratch and wear the stainless steel lining. For a masonry chimney, you need a 7 inch chimney cleaning brush that is at least as big as your chimney lining, otherwise it will not be close to the side wall of the chimney and will not play a sufficient role. If you buy a 7 inch chimney cleaning brush that is too big, it will be difficult to move and clean in the chimney.

Choosing a suitable 7 inch chimney cleaning brush is particularly important for both the chimney and the family, because the chimney is not cleaned regularly, in fact, there are great hidden dangers. Therefore, 7 inch chimney cleaning brush cannot be chosen randomly. If you do not know how to choose, I recommend Aoqun Brush Industry.
