Washing regular utensils is a no-brainer, but gold-plated silverware is valuable, which means that cleaning it requires a little more effort. Washing gold-plated silverware in the dishwasher is not advisable, because it may become damaged during the process. To remove tarnish from gold-plated silverware, you should polish and wash it by hand, but you must do so correctly, or you may scratch or dull the surface of your gold-plated silverware.
Make a paste with baking soda and water. Add 2 tbsp baking soda and 1 tbsp water to a bowl and use a spoon to mix the two ingredients together.
Rub the paste on the gold-plated silverware with a clean cloth. Keep rubbing until you see the black tarnish come off.
Apply a drop of mild dish soap to a sponge dampened with warm water. Wipe the gold-plated silverware clean with the soapy sponge.
Rinse the gold-plated silverware under a steady stream of cold water. Dry it immediately with a dry, soft cloth, as water can cause it to tarnish again.
