Cleaning Egg?

After a high temp cook it should be clean enough, if you only low and slow, you might want to do a burn out, otherwise I think it is self cleaning. 

im due for a clean burn! Usually do it following a pizza night, which im due for also. I run right around 600 dome for pizzas, after an hour of that, it's usually fairly clean. For a full clean burn i fill it up with lump and let it run wide open till it's out. Lid's usually stuck shut, but with a well seasoned nomex gasket and putty knife it usually opens back up unharmed. If you slightly burp it along the way you'll find that it won't usually get stuck. BTW, when you're doing a clean burn, especially your first one, be prepared for grease to weep thru the outer ceramics of the egg, i was super worried, but if you wipe it down with a wet towel while it's hot it cleans up fine.
