hey guys, I've had my mflb for several weeks now and I am loving it as much as I did when I first got it. However, I smoked a trench of kief out of it, and it seems that a tiny bit combusted and turned the kief surrounding into a sort of hash on the screen. It builds up as I smoke untill it gets to a point where it dosen't seem to get much bigger. But if I take it out, it builds up in the exact same spot it was before. I think it is on the other side of the screen too but I can't think of a way to clean it. I was thinking that I could drop a few drops of ISO through the screen and hope that dislodges it, but I'm not sure if that will cause problems or not so I wanted the cities opinion before I tried it out.
