Stainless farmhouse sink look great when they are impeccably clean, but when stained or dull, they give the illusion that their kitchen is unclean. Fat and food stains every day, such as coffee and spaghetti sauce, can resist ordinary dishwashing detergent, but are easy to remove with common household materials. Once the stains are lifted, a quick polish will restore the stainless steel sink to its original luster.
Clean the sink with dishwashing detergent to remove dirt from the surface, excess grease or other particles. Rinse residue with warm water and wipe the sink dry with a soft cloth or paper towels. Mix 2 to 4 tablespoons, of baking soda with 2 teaspoons and salt to make a non-abrasive cleaner. Sprinkle the mixture over the problem areas and rub with a damp cloth or sponge. Salt works as a natural abrasive, while cuts baking soda through the grease and removes stains.
Rinse the area with lukewarm water to remove the residues of baking soda. Baking soda leaves a blank film on the surfaces if it is not rinsed properly. Cover the inside of the sink cleaned with olive oil to restore the natural shine to the stainless steel. Rub the oil in the sink and clean excess oil for a gas sink. Alternatively, spray rubbing alcohol on the surface of the sink and wipe with a soft cloth to leave it shiny and clean.
