I do full boils on my gas stove- placing my pot over two burners that are each on full blast. I try to make sure everything is clean as possible before I start brewing, but inevitably I get very hard black crud all over my stovetop, the burner grates and the burner covers. I'm pretty sure it is from tiny amounts of wort that somehow end up on the stove. Because of the length of time and the amount of heat kicking around under the pot, the sugars and other gunk solidifies and never wants to come off again. I've had some success soaking the grates and covers in bleach and water, but it is still very hard to get EVERYTHING off. I've tried soaking in OxiClean as well, but I thought the bleach was a little better.
Does anyone have any tips for how to clean this hard crud off? It sucks!!!
