What is the best method for cleaning off the stuff that gets baked on to the firebox surface:
I've tried using a plastic razor blade but that only gets the stuff that is still loose. If I try to scrape the stuff that's been baked on for a while, it doesn't come off and/or the plastic razor blade breaks.
Is there any chemical that would loosen that up without damaging the surface?
Would a steel putty knife work, or would that ruin the surface?
