Drip-pans...

Okay, so the best way I've discovered to clean your under-the-burner drip pans is: Take them all out and put them in a bucket or dish pan. Run the hottest tap water you can, or even add some boiling water, just enough to cover them. Add about a cup of dishwasher detergent (Notice that this is the powdered granule type made for dishwashers, not the liquid soap kind.) Stir to mix and coat each pan. Allow to sit overnight. The next morning you should be able to wipe or scrub off most of the scum and cooked-on gunk. It takes a little elbow grease but is WAY cheaper than buying a whole new set! This method also works for oven racks but you have to soak them in a huge container--in my house this means the bathtub.
