Question from my wife this time as she's realized what a resource this place can be: We've got a cast iron waffle maker designed to use on a stove. I don't have a picture handy, but it's a round hinged deal with a base that sits on the burner. The problem is cleaning it and / or keeping it clean. It winds up a gloppy mess and nobody wants to use the thing. Any of you have one and how do you use it? Thanks!
