Aluminium vessels tend to pick up stains from food that is cooked in them. The stains are not harmful, but are unsightly. Periodically, boil up some vinegar or a dilute solution of cream of tartar, lemon juice or other very mild acid with which to remove the stains. From time to time you can use a pan scourer or soap-filled steel-wool pads, but don’t do this too frequently, as you could leave small pits in the metal that will merely collect small fragments of stain all over again. Pits can be smoothed out with wet-and-dry sanding papers.
