Question: I've been given a tip, and want your opinion. A co-worker suggests that I burn a Potato in my woodstove. it is not a catalytic... he suggests that the chemicals released in the burning of the potato reduce creosote build up... 'a potato a day keeps the creosote away' Answer: That is really a new one for me. I can honestly say that I doubt this is true. To reduce creosote, use the proper burning practices shown at http://hearth.com/what/specific.html and use the safe chemical additives like ACS that you can purchase at your local fireplace store or home center.
