For darkening, manufacturers suggest simmering something acidic such as apple or lemon in the pan. For burnt-on food, first soak in hot or cold water to soften it. Aluminium touched by alkali may also turn white and powdery. Aluminium can darken through reaction with water even without baking soda. Other alkaline cleaners (sodium sesquicarbonate, dishwasher detergent and so on) are likewise unsuitable for aluminium.
