Bistre A9 powder is designed for professional maintenance of flues in chimneys, stoves, inserts and boilers that use wood or coal. It works by gradually breaking down the soot residues that build up as a result of incomplete combustion, thereby reducing the risk of chimney fires and loss of efficiency.
The product is applied directly to glowing embers. Through a chemical reaction during combustion, it releases oxidising agents which break down the soot deposits clinging to the walls of the flue. It can be used as a treatment once signs of build-up have appeared, or as part of a regular maintenance routine to prevent the accumulation of deposits.
