Vantage - you get two gold stars! Don't know why I never thought of these things before but you definately got me to thinking and turned on the light-blubs
I've been using Bar Keepers Friend, a Scotch-Brite pad, and a lot of elbo grease. Never cut the grease 100% - but I got most of it off. But, the idea of Orange GOJO kicked the old brain into thinking mode. I know GOJO from my teen years when I worked on cars a lot, and the Orange got me to thinking about the infomercials for orange oil cleaners. and since oil soaps cut grease ... cogs in the brain click-click-clicks ... I remembered I have a bottle of Murphy Oil Soap. So, I got up from the computer, went into the kitchen, and tried out my idea on a Calphalon anodized pan that had a little grease residue on the bottom like superman described. I gave it a good spray of Murphy, a gentle rub with the scotch-brite, and rinsed - it was almost totally clean! I wiped it dry, repeated the process ... it hasn't been this clean since it was new!
Then the second light blub went off ... how to prevent it. Yep, cook on one burner and it spatters a little onto another burner ... not enough that you really can see it but enough to mess up the bottom of the pan the next time you use that burner. Now I see why they have those funky cheap burner covers at WalMart.
