After work I removed the grimy rain cap and did the brush thing several times. This is a fireplace insert where the liner drops straight down to the top of the stove. The liner and top 4 foot double wall insulated section looked real good before starting the sweep and now looks great. The two pictures of the stove inside indicate I didn’t even get enough creosote to fill a 24 ounce bottle, but the cap was a total mess. I have burned 24/7 for 6 straight weeks since the last cleaning. Needless to say, I’m running tonight without the cap wondering what you guys think. I don’t want to leave it off when the rainy season hits but for now we should be fine. So do you think I have typical deposits on the cap? My wood burns just fine with only some smoking but seldom sizzling of water out the cut ends. Thanks
