There are a number of easy strategies that you can use to remove rust from your stainless steel cutlery. The rust that appears on your cutlery is likely a stain from other flatware or cookware that is rusting. When trying the following options, it is important to note that excessive force is not necessary and if it seems that force is what it takes, you need to switch to another cleaning solution. Avoiding excessive force will make it less likely that you will damage your stainless steel cutlery.
Lime Juice and Salt
Put your silverware on a pan and apply lime juice and salt to the affected area. Let it sit for a couple of hours and then take an old toothbrush and gently brush the area. Rinse the cutlery with water and check the results.
Take a rag and moisten it under the faucet. Dab the moist end of the towel on a plate that has baking soda on it. Gently rub the rag on the silverware, rinse, and look at the results.
Sandpaper should be your last resort because it is easy to damage your cutlery with sandpaper. Start out sanding with a grit as high as 150. Be sure to sand in the direction of the grain of the stainless steel. Choose a small test spot and see how little pressure you can apply to get the best results.
