I often see discussions concerning effective ways to clean stove glass, here's my question: Will I encounter great difficulty if I only clean my glass, say once or twice a burning season? Will it still come clean without too much elbow grease? My stove is running 24/7 and hasn't dipped below 300 degrees since Oct. I get a nightly build-up of black when I set up my overnight burn, but the next day a hot fire turns the black to a white ash. I'm not inclined to cool the system down to clean glass, nor mess around cleaning 300 degree + surfaces. Any thoughts?
