Q: I've got an aluminum pot that's turned black inside. Is it salvageable?
A: So you want to make it shiny again? Try this:
1. Chop up a small apple.
2. Place in the pot with enough water to cover.
3. Bring to a boil, then simmer for eight minutes.
The acid in the apple should work its magic and you should be able to wipe off the black stains with soapy water and a sponge.
