This liquid form of our popular Creosote Remover is great for all stove and flue types but best for pellet stoves where granules would fall through the burner pan. Spraying on an existing fire or pre-treating fuel before adding is all it takes to make your chimney a safer, more efficient part of your home. Heat-activated liquid evaporates and works to remove creosote buildup from inside a chimney. As the chemicals penetrate the sticky, tar-like creosote it turns it into a loose, powdery, non-adhering ash that can easily be brushed away. Weekly use will prevent further creosote from forming. Safe for use in all types of chimneys, fireplace inserts, wood stoves, airtight stoves, and free-burning fireplaces and will not harm catalytic converters.
