We have a Jotul wood stove that we have cleaned each summer by the dealer. This fall when I went down to start a small fire to take the chill off the house I couldn't open the door. I finally got it open using a dead blow hammer and found it rusted all around the door. The opening latch is rusted solid. I have two questions: One how would you clean off the rust and two what do you think caused it? I suspect the person that cleaned it used a cleaner and left some moisture inside the stove. The only other option I can think of is I had knee replacement and never got around to setting up the dehumidifier in the basement which I usually do. Could it have been too moist in the basement? I'm calling the dealer Monday and see what they have to say. Thanks for your thoughts.
