It is generally not recommended to put sterling silver in a dishwasher. While sterling silver is a durable and valuable material, the dishwasher can cause several problems that might damage or tarnish it:
Scratching: Sterling silver is relatively soft, and dishwasher detergent and other dishes' movement can lead to scratching or abrasion.
Tarnishing: The high heat and humidity inside the dishwasher can accelerate the tarnishing process of sterling silver, causing it to become dull and discolored.
Chemical exposure: Dishwasher detergents and rinse agents may contain chemicals that can react with the silver and cause discoloration or other adverse reactions.
Displacement: Sterling silver items might move around during the dishwasher's cycle, bumping into other dishes or each other, potentially causing dents or scratches.
To maintain the beauty and integrity of sterling silver items, it's best to wash them by hand using mild dish soap, warm water, and a soft cloth or sponge. Avoid abrasive scrubbing pads or harsh cleaning agents. After washing, make sure to thoroughly dry the items to prevent water spots or lingering moisture.
If you have sterling silver flatware or other valuable silver items, it's essential to handle them with care and follow proper cleaning and storage practices to preserve their appearance and value.
