Hi all.  I dont clean the glass as often as i should and hence it has developed tough to clean stains on the glass.  Stains are dark brown/black and wont come off with damp paper towels which is what I normally use to clean the glass with.  Other times i use glass cleaner to really clean it maybe every other month.  The stains it has developed only seem to come off if i scrape it with a fingernail.  Can i use a scotchbrite pad to clean it with soap and water?  Will that damage the glass?  Thanks.
