In my Big E Breckwell after a week the ash is caked on the sides of the burnpot like concrete. I just replaced the burnpot and never noticed that on the old pot. I scrape the pot daily with a screwdriver and probably not getting the sides as good as i should. But man is that hard. Is hard buildup normal? I clean everything weekly and scrape the pot down to bare steel but thought i was going to have to get the hammer this week
