Chimney fires are destructive, deadly and extremely difficult to extinguish, so I use this kit once a year to clean the creosote buildup out of my chimney. It's dirty work (think Mary Poppins) and involves getting on the roof, removing the chimney cap and using a battery-powered drill to work your way down the chimney from the top, installing additional segments of rod as you go.Tape a sheet of plastic over the opening of your fireplace and make sure it's as airtight as possible, unless you want to clean a fine layer of creosote off literally every surface in your house later.This kit is a good value for the money, the brushes are a bit flimsy but I only use it once a year so it's good enough.
