You can remove burnt food from a glass baking dish by spraying it with oven cleaner and letting it soak for 30 minutes. This makes the burnt-on residue easier to wipe off.
Instead of using expensive silver cleaners, put a dab of toothpaste on a clean
rag and rub it on. After you've rubbed it in, just clean it with another clean
rag. Your silver will look like new!
