My husband and I cleaned our chimney this weekend. You would think being that this is our 7th year with a wood stove we would have the procedure down pat. Nope. I pretty much looked like Dike Van Dyke from Mary Poppins before all was said and done. We use the Sooteater and clean from bottom up. We put a bag around the pipe to catch the soot. The bag got twisted 3 times and I could see soot floating through the air and particles falling all over the stove and hearth. After we got the chimney clean we went to put the pipes back on and couldn't remember which way they went. At first we thought one was upside down. I had taken pictures last time we cleaned so had to go find them to see if it was on correctly. Cleanup of the room took a while. And after all that we only got a couple tablespoons of stuff that was very fine. But chimney is clean and I am thinking maybe next time we go 2 years between cleanings. We do not burn to heat our house.
