ultra-smooth surface of Corningware always comes clean in
the dishwasher.
That depends. I have known some Corning Ware situations where a Corning piece or two had almost permanent residence in the lower rack of the home's dishwasher because someone was "damned if I am going to scrub those pans." Sometimes there is residue left behind even after a pot smasher cycle, even when you use lube, I mean Pam.
Paul, before you go roasting meats and cooking things that splatter, remember that the chrome liner cannot be cleaned with anything even slightly abrasive. Even if something does not scratch the chrome, you can bruise the finish or make a mark that ruins its beauty. You would save yourself a lot of work if you used a porcelain-lined oven without a glide-up glass door for things that splatter.
