I'm new here, tried searching for this topic and apologize if it's already been discussed. I have a good wood stove and have had no problems in the last 25 years. This year I purchased 1 cord of Almond wood and 1 cord of mixed soft and hard wood. After about 30 days of constant fires, I began to smell a chemical smell. It continued to get worse to the point of aggravating my asthma and causing burning eyes. I had the chimney cleaned, no affect. When the stove is cold (to remove all the ash) I can smell a chemical odor from inside. I have replaced the insulation blanket and fire brick. There was no creosote deposit anywhere inside the stove. I believe it possible the Almond trees were sprayed with either an Herbicide or Pesticide prior to them being cut down. My question is: is it possible the steel inside the stove has absorbed the toxin and can it be removed?
