Hey All, This weekend my Daughter and I were sitting by the Allagash and the doors were closed. The stove had been running for about an hour and we decided to open the doors. I don't know why but the heat seems to come out better when the doors are opened. Anywho, I go into the kitchen and get a pot holder so I can open the now very hot door. I grab the first door with the pot holder and smoke whisps upward. I thougt this was strange but really didn't pay that much attention to it. I opened the second door with no problems. A little while later my DD says, "Way to go Dad, you broke it". I look and she was pointing to a mark on the glass left by the pot holder touching it. I shut the stove down, let the glass cool, and tried to wipe the mark off but it felt like it was "in" the glass. Any suggestions on how to get it out/off? The manual says not to use anything abrasive but I have used Scotch Brite on my wood stove glass with much success.
