First, I know it is some kind of ceramic and is far more shatter resistant than regular glass. But I'm not sure if it is OK to try and clean it with a damp paper towel while still hot. I sometimes have a foggy surface that won't burn off with a hot burn and I'd like to clean up the glass without letting the stove run cold. Do you ever give yours a quick cleaning even when it is hot/warm?
	
		
			
		
		
	
				
			
	
	
  You forget how much film stays on the glass till you clean it.  Not any black soot, but just a fine layer of ash.
