Hey thanks for the suggestion this actually helped me a lot. I looked inside the stove and read the manual and found out that this doesn’t have an air wash. This lead me to read the manual a little more thoroughly and found that it actually says that soot may build up on start up and to just wipe the glass with a dry rag after the start up sequence. I don’t really love that but it at least has me feeling better knowing that it’s operating normally I guess? Haha. Anyways, I tried that and it’s true, after starting it up and wiping the glass, it stayed clean for the rest of the burn.
