If you intend to bum wood continuously, some time will probably be necessary each year for “house cleaning” or chimney maintenance. Chemical chimney cleaners are not particularly effective in removing heavy deposits and should be used with caution. However, as preventive measure they may have a place. A more effective approach may be to seal the front of the fireplace to keep soot and dirt out of the room and use one of the mechanical methods of cleaning. A rope may be used to lower and raise tire chains inside the flue or a weighed burlap sack filled with straw or chicken wire may be pulled up and down the chimney flue. Another method of cleaning the chimney is to work a small evergreen down the chimney. When the tree is pulled back up, some of the creosote and soot will be dislodged. Commercially-available flue cleaning brushes are available. When cleaning the chimney be careful not to knock out mortar joints or damage the flue lining.
If cleaning the chimney sounds like a messy job, you will be particularly well advised to follow preventive maintenance procedures. When possible, burn only well-seasoned hardwood which has been dried at least 6 months. Seasoned wood produces less creosote and as shown in
