Removing Glazed and Tarry Creosote With Cre-Away

TwitterEmailFacebook

At Lindemann Chimney Supply we like to pass along products that we have used with success. The best product we found for removing the tarry, gooey creosote is Cre-Away. Itworks to dry it out making it easier to remove. It is also good for other types of build-up including severe third-degree creosote. It modifies the third-degree creosote glaze by converting it into a more brittle state that has a different expansion/contraction rate than the flue. During heating and cooling cycles, the creosote starts to lose its adhesive properties making it easier to remove by chimney sweeping. First, a reactive agent neutralizes the creosote making it less corrosive to metal components and less flammable. Second, a dehydrator absorbs the oils and moisture contained in some forms of creosote. Third, a combustion inhibitor helps reduce the chance of chimney fires. Finally, a magnesium catalyst helps break down third degree creosote when the flue is heated by normal use. Cre-Away is effective on all types of creosote. Not recommended for catalytic stoves.

Here’s a photo showing how Cre-Away works. The top flue is the glazed flue. Moving down, the second flue has just been coated with Cre-Away. The next flue shows how Cre-Away as broken down and loosened the creosote. The bottom flue shows how well the Cre-Away worked.
