I found the most wonderful stuff...it is called Dawn Power Dissolver. I found it at Walmart with the dish liquid. It is a gel in a spray bottle. I have porceline grates on my stove..and the stuff gets hard there..I just take the grates off..put them on newspaper and squirt the get on them. I let them sit for a few hours. Then I scrub them with a nylon scrubber. You can use this stuff on the pots and pans also. The hard baked on grim comes off a lot easier. After I use in on my pans, they have copper on the bottom...I take a half of a lemon and put salt on it to finish them off. You can even spray this stuff on the stove top to clean around the burners. I clean the stove top with barbasol shaving cream..just wipe it on..ket it sit for a few minutes and wipe clean.
