The door on my Jotul Combifire 4 needs lubrication. The guy at Jotul USA in Maine said PB Blaster works well, but I had a friend once scare the heck out of me by saying heated PB Blaster can turn you into an instant vegetable. I'm starting to think my friend was wrong because I've seen another person on this forum recommend a silicon lube spray. That said, i don't want my first fire inside with this stove to be my last fire with a healthy brain. Does anyone here think a silicon spray is a bad idea on the Jotul stove door?
