Hello! I'm new to the forum and new to Egg ownership too. I just acquired a large Egg via Craigslist and I am looking forward to some awesome grilling. But the Egg I bought is really dirty and grimy. I'd like to clean it up a bit before using it. I know not to use detergents or solvents, but is it OK to use plain water and a scrub brush on the inside ceramic surfaces? Am I wasting my time cleaning something that will never be clean anyway?
