I burned my copper whistling tea kettle. I can get the outside reasonably clean, but worry about the inside. How do I make sure it's free of nasty stuff inside?

You can smear ketchup or tomato sauce over the inside of the kettle, let it stand 10 minutes, then wash the kettle.
The acid in the ketchup or tomato sauce would probably work if you can get inside the whistler pot to smear it on. If not, try filling the pot with water, add about 1 tablespoon of baking soda, and let it boil for several minutes. Wash it out and rinse. I know this works on pot that have food burned onto the bottom.
