Cleaning Member's Mark
I just tried something on the outside of my grill that worked like a charm. I had a little brown coloring starting to happen on the top, and also some tiny black grease splatters. I tried "Bar Keeper's Friend" on a damp sponge and wiped very carefully, and gosh darn, the thing is blinding me again. Very shiny. I also finished with Stainless cleaner. I also tried it on the grills themselves, and it worked better than anything else. Really shines them up. Give it a try.
