Hotspot Flue Free Chimney Cleaner is a combustion deposit conditioner that works by rising into the chimney on the flue gases.
On contact, Flue Free Chimney Cleaner reacts with the acids in the tar/creosote deposits and ‘fluidises’ them.
Absorbents in Flue Free Chimney Cleaner then soak up these fluids, producing a shrivelling or drying action, which weakens the bonding to the chimney surface.
These deposits eventually fall back down the chimney or are removed more easily by sweeping.
