The first rule in caring for Pewter is USE IT. Handling gives Pewter its distinctive patina. After each use, hand wash your Pewter in mild soap and water, followed by towel drying. An occasional cleaning with an ammonia based glass cleaner will remove any soap film. We do not recommend putting your Pewter in the dishwasher. Don't use your Pewter as a food storage container, and always line your Pewter with glass or plastic if you intend to use it for plants or flowers. With very little care, your Pewter will retain its beautiful luster for many years.
