Methods of cleaning silver should be determined by the valued placed on it, monetary or sentimental, and the design of the pattern. Hand rubbing develops patina on silver which adds to its beauty. Polishing silver while wearing rubber gloves promotes tarnish. Instead, choose plastic or cotton gloves. Silver has enemies.
Rubber severely affects silver.
Rubber corrodes silver, and it can become so deeply etched that only a silversmith can repair the damage. Raised designs can be lost permanently. Avoid using storage cabinets or chests with rubber seals, rubber floor coverings, rubber bands, etc. Other enemies of silver include table salt, olives, salad dressing, eggs, vinegar and fruit juices. Serve these foods in china or glass containers.
