So here we are, end of season and counting...still burning and burning...been 24x7 this week, hope to put the stove to bed soon so I cna start working on next year's wood. Trouble I'm having is very poor efficiency. Slow burning, very smoky and I get massive smoke intrusion into the house when I load. Stove won't get hot enough to do a secondary burn, I'm thinking I've got enough blockage to partially smother the fire, looking at my vent cap I see alot of black, which I take to be creosote buildup...logically if there is some there there is probably a nice lining of it all up and down my stack. Its going to be awhile before I can have it properly cleaned from the rooftop and I'm wondering if anyone here has used any products that have proven effective enough to bother with. I want to try to improve my burning quality and of course want to make sure I don't wreck my stove. Stove is a Morso 3610, its a non-cat EPA stove, less than 1 year old. I located two items today, one is called Jiffy Stick, its an anti soot and anti creosote tube of sodium chloride mainly for oil burners, but allegedly can be used for wood stoves as well. The other product is called CLR (or similar initials...its not the calcium lime rust cleaner), which is a log thing...you toss it ina nd let it burn out and then don't use your stove for a few months so it all dries up (store guy's advice, not the box). I've heard others here mention tossing in some TSP and others gainsay the advice, so I'm wondering if there is a consensus here on any product...obviously sweeping is the best choice, but its not a viable option for me in the next month and I'd prefer to use the stove than the boiler if I can. Thanks.
