I've been having a big struggle with creasote in my boiler heat tubes. But, this was a self-inflicted wound - I knowingly used poorly seasoned wood, trying to make it through the Spring. My bad :down: . Had I known what what happening in the tubes, the boiler would have been shut down at the beginning of March. But, unfortunately it's not as easy with an Econoburn to get at the tubes as some others - the top and back plates have to come off in order to pull the turbs to get a look at the tubes,. And, the turb lever was working fine, and the boiler was heating well so I didn't suspect that creosote was forming on the tubes. Pilot error. Anyway, I've been trying a bunch of stuff, with no luck - this creosote would make great epoxy. Piker sent along what looks like a very effective grinding method developed by Gary Barker, but I've got a bit of elbow tendinitis right now, and can't handle the torque from the heavy-duty grinding. Lighter grinding using cut off washers works, but is REALLY slow. So yesterday I was poking around for other possibilities on the web, and came upon "how to remove creosote". It said, just mix wood ash with water, apply to the creosote, and brush or scrape off. Snake Oil, I said to myself. But, I filed it away - try it tomorrow and have a laugh. This evening I mixed up some of the Snake Oil, and applied it to the ledge of the top chamber. I waited a minute or so, scrubbed lightly with a wire brush, and then wiped with a rag. A quick Holy #@%! popped out when I saw the patches of bare metal (with very little effort). Then I applied some to the top section of an uncleaned tube, and spun a wire brush on a drill (the same wire brush that the creosote was laughing at last week). Voila! - it was coming off :lol:. Early next week I'll work out a delivery method to get the Snake Oil to the work area, (probably just loading a pile onto the back of the wire brush will work), and I'm fairly confident that this will finally get the job done. I wanted to share this information with others - I know that Reflex1957 was having this same problem, and I would guess there are others as well. I also wanted to post the url of the web page that I found this on as a thank you, but can't find the site - my web history gets cleared daily - I'll keep looking.
