Warm today in Akron, OH, high 60 degrees, so I decided to give my chimney a good "freshen up" check and clean for creosote build-up since I have been running now 24/7 for about 2 mounts. Took the chimney cap off and the inside was coated in wet creosote, maybe 1/32" to 1/16" thick. I set it aside and cleaned the chimney got maybe 1/2 to 1 cup of dried creosote out. Then tried to get the cap cleaned up with little luck using a wire brush. I pulled out the trusty soldering tank loaded with Map Gas and went to work heating up the cap. In about 10 minutes all the wet creosote dried up and some even ignited. After that, a few strokes with the wire brush and it was like new. Anyone else use map gas (or propane) to clean their chimney cap of wet creosote??
