The TAI FUME OFF fireplace cleaner is suitable for every fireplace, chimney (simple or energy-efficient), and the stovepipe of the wood stove. By using the product approximately 1-2 times per month, we keep the walls of the fireplace clean. It is easily and quickly applied to the chimney of the fireplace and the stovepipe: In a strong fire, we throw the product (as it is closed in its box) in the center of the hearth. We use the product 1-2 times per month to keep the chimney of the fireplace or the stovepipe clean from soot and grease, thus protecting them and preventing them from getting clogged. We can also use it to clean the walls of the fireplace: In a strong fire, we open the burning wood along the walls of the fireplace and scatter the contents of the bag along the burning wood. We will leave a blue flame to burn, which cleans, as we will see, the walls from soot.
