Okay, there it is. You see those two marks above the draw hole? That is not some kind of gunk or dirt on the box, it is burning from the inside out. I haven't used the box in a few days because it taste like burning wood .
Looks like magic flight will take care of it, but im wondering what could have possibly caused this? I have not combusted in a very long time, I'm just at a loss.. Could the use of the concentrate trays have anything to do with this? I'd love to get some more opinions.
