Looking at comments on related threads, I see that some folks are cleaning several times per year. I burn 24/7 during the cold months (near Boulder CO). When I clean, most of the crud is light brown or gray dusty ash, not "greasy". Question: If there isn't glaze or patina in the pipe or chimney -- and if you're not getting a pant-load of ash when you clean, isn't once per season enough?

New wood burners need to check their chimneys once per month. Clean only as needed. The reason I give for this is that most new wood burners think they have "seasoned" wood but really can't tell and just go by what someone told them. Therefore, why take any chances? Check the thing. If it needs cleaning, clean it and then change something. Get some different wood....if you can find it.
