I was cruising on Facebook and saw a post about cleaning creasote build up in a chimney. Some folks actually said dry wood and hot fires but some were saying aluminum cans and eggs shells and all kinds of stuff. The person who said aluminum cans said that aluminum is in those creosote logs. Didn't get an explanation for the eggs shells other than "grandpa did it". I don't have any issues with my chimney but just wondering if anyone has heard of this. I though it was interesting.
