The following is a section from Chimney Cleaning Logs Position Paper with support from Hearth Education Foundation.

The Chimney Safety Institute of America (CSIA), a non-profit, educational institution focused on the prevention of chimney and venting hazards, is concerned about the consumer use of chemical chimney cleaning products to the exclusion of conventional chimney inspections and cleaning. These products often are promoted for their ability to remove a portion of the creosote from a masonry or metal chimney interior through catalytic action when burned in a fireplace or wood stove. The CSIA believes that the use of these products alone is not an adequate substitute for mechanical chimney cleaning and inspection because it does not provide the same level of protection to the chimney system. Current promotional claims for some of the products may be creating a false sense of security among consumers.

It is the consensus of qualified experts that chimney maintenance is best achieved through annual inspections, and mechanical sweeping, by trained professional chimney sweeps as frequently as needed. Chimney inspections often reveal hidden problems with a chimney structure that could be potentially hazardous. Mechanical sweeping of chimneys not only removes layers of creosote from the chimney surface, it removes the resulting loose soot and creosote from the chimney, fireplace, or wood stove.

CSIA believes that the optimal method for cleaning a chimney is by a mechanical brushing of the chimney in conjunction with a complete evaluation of the system by a qualified chimney professional. The CSIA and the National Fire Protection Association recommend annual inspections.
