You can get rid of rust spots with a stainless cleaner or stainless brightener, such as Bar Keepers Friend. Or you can make a paste of baking soda and water, and apply it with a soft cloth, rubbing gently in the direction of the grain. Samsung says to use 1 tablespoon of baking soda to 2 cups of water, while Kenmore says to mix equal parts.
It’s best to follow the instructions for your appliance brand, or call the manufacturer’s customer service line for advice specific to your model. Once you’ve removed the rust, rinse with clean water and a soft cloth, then dry.
Keep an eye on areas where you’ve seen and cleaned off rust; these spots are more likely to rust again in the future.
