Does anyone have a solution to getting burnt on gunk off of the stovetop? The boyfriend likes to be a messy cook and always spills stuff out of pans onto the stove and now there are burned spots that I'm tired of looking at. Would an oven cleaner work if I let it sit for a while? I couldn't keep up with his messiness because he lived here alone the first 6 months so some of it has been there for a while. I got up what I could with a Mr Clean Magic Eraser thing, but some of it just won't budge! It's even on the burners too. Thanks!
