How to prevent or clean black or yellow deposit on stainless steel product, especially gas stove?
Firstly, try soaking the pot in hot water with dishwashing detergent.If this does not work, try adding water to the pot and bring it to a boil. Sometimes this will break up the food deposit. If all else fails, use a mild abrasive scouring powder or non-metallyic or stainless steel scouring pad to remove stubborn deposits. These may scratch the surface. If there are obvious polishing lines, try to rub in the same direction as the lines to minimize surface finish damage.
