To clean discolored aluminum you can also heat 2 teaspoons cream of tarter per quart of water. It would be best to let the cooker soak in the mixture, but that might be difficult depending on the size of your cooker. Lemon juice or lime juice should also help because they have citric acid. You could cut a lemon in half and rub the halves on the cooker, then try scrubbing with something that has some texture to it (rough sponge or steel wool). The try the vinegar or cream of tarter mixture again. Whatever you use, don't try bleach as it is highly alkaline and dissolves aluminum. This leaves copper deposits can make it turn black.
