My wife does it similarly. We wait until right before we're going to stoke the fire again and it's just a few coals in the firebox. We open the door and while I'm scooping ash out she is cleaning the glass. We've actually found that the glass cleans much easier when it is a bit warm. If it's hot enough that it makes you uncomfortable when using a papertowel on it then it's probably too hot to clean.pen said:0.156 ounces.
J/K. In all honesty, I have no clue and I can't see anyone else having one either.
I'll say this general statement however: The hotter the glass is, the greater the chance you have of breaking it by spraying a liquid on it.
Most stove manufactures say in their brochures not to clean the glass when "hot".
If company is coming over in the winter I've been known to open the door when the stove is down to coals, let it cool in the room air for about 5 mins, then clean quickly.
I haven't broken the glass yet but that's not to say it won't happen next time.
