    Abstract: A processed solid fuel composition incorporating agents for destroying creosote and soot within flue ducts and chimneys of fireplaces, solid fuel stoves and other heating devices is disclosed, along with a method for its manufacture and a method for its use. The composition is made up of a combination of compressed cellulosic particulate material and a chemical and/or catalytic creosote and soot removing agent, and is molded in the form of a fire log in the preferred embodiment. The composition may be used alone, but is ideally applied to an active fire to treat a chimney flue by combined heating and chemical disaggregation of accumulated creosote and soot deposits.
