They say, soups and sauces just don’t the same unless you prepare them in stainless-steel pots. But all the cooking and washing has left your pot chalky and dull. You can easily remove those water marks that leave a gritty film by covering its bottom with a thin layer of baking soda, then add a cup of vinegar.
In a bowl, mix 1/4 cup of baking soda with a drop of dish detergent until it forms a paste. Use a clean cloth, then apply the paste to the outside of the pot. Let it sit overnight, then rinse with a moxture of equal parts water and vinegar. The combination of vinegar and baking soda dissolves the layer of calcium deposits on the pan and the paste helps to effortlessly remove any remaining stains.
