Is it safe to use aluminum foil in a microwave?

Please, do yourself a favor, keep metal out of the microwave oven. There are one or two manufacturers who have made pans that are absolutely smooth with a rim that is rolled and doesn't close in on itself. But unless you absolutely know it is safe, don't use it. It does something called arking which is like having a miniature electric storm in your microwave. It can burn out your microwave oven. And the same thing is true for something as simple as aluminium foil. Instead, put plastic on it. Put paper towel that you fold over a couple of times. Put a lid on it. There are all kinds of covers you can use. Just don't get metal in there.
