This is, hopefully, a legitimate cookware question though the piece is a built in outdoor gas BBQ grill. I'm doing my regular Spring "make sure it's as clean as possible" thing and am running into some very stubborn, caked-on build-up under the front edges of the grills. This is probably from significant grease build-up, and complicated by a couple of incidents of leaving a burner on overnight. Anyway................. I've tried several things, but the blackened stainless underneath the build-up is not cooperating.
I'm using a plastic scraper and every solvent I can find that says it's safe on stainless. I've seen some online material about a paste made from baking soda and vinegar but haven't tried it yet. Any ideas of what might loosen up this stuff will be much appreciated.
