Ok, I bought an egg in March and had my sons assemble it for me. I grilled in it once and haven't had time to use it since.....a crime I know, but I am single and all my kids packed up and moved to Phoenix and I have little/time or reason to cook anything. My friends have a BGE and I know they have never had this happen. It has been very rainy this Spring and I do not have a cover, but then again neither do my friends. This is the grossest thing I have ever seen. Any suggestions of how to clean my Egg and what to do to keep it from happening again? I appreciate any direction you all can give to me!
