Thanks for all the advice. The glass was clear, accept for a couple of spots that was mostly clean with black speckles, and a line of dark thick black crust along the bottom of the glass. I tried the ash and news paper, and the deposits just giggled at me. However a spray with the cleaner and a light scrape with a razor blade worked like a charm. I had been concerned of scratching the glass, so I was trying a plastic putty knife but that didn't work. I tried my best last winter to keep it clean, but burning 24/7 made it difficult.
It seemed like the glass would stay pretty good until I woke up in the morning. I figured that loading the firebox all the way up, logs were falling and resting on or near the glass causing the buildup. Of course it didn't help I'm sure that the wood I had to (gasp) BUY last winter my first wood heating season were less than actually "ready to burn" as I was promised.
Again, thanks for all the tips, I'll incorporate them this next heating season to see what ones work best for me to keep the glass clean.
