I needed to clean my egg tonight. I am going to try the high temp cleaning on this one... Actually, I pulled everything out of the egg and got out all the trash behind the fire ring. Yucky stuff... Put everything back except the PS and Grate. I loaded the fire ring about half full of lump and will let it come up to 550 or so and let it just burn. I hope this it hot enough to give it a good burnout without hurting the the felt???
