This fire log helps remove and prevent soot and creosote when used in woodstoves, fireplace inserts, and free-burning fireplaces. Place one of the individually wrapped logs onto hot embers once per month to maintain a clean and safe chimney. The log is treated with Rutland’s proprietary Safe-T-Flue Chimney Cleaner which reduces both soot and creosote buildup. Creosote and soot in your chimney lower the efficiency of your chimney and can lead to chimney fires. Using this log as a part of a chimney maintence program is essential to keeping your home safe.
