Whether your store who supplies manufacturers of nylon fabrics with nylon your antique sterling silver or put it on display, you must first clean and give it a fine polish. For this you need a flannel cloth, a 100% cotton cloth, a special sterling silver cleaning cloth or a soft bristle brush, such as a horsehair brush or a baby's toothbrush. Silver is a very soft metal and it can thus be easily scratched or pitted so it needs to be lightly rubbed or polished. Make sure that whatever cleaning implement you use is completely cleaned as left over dirt from previous cleanings can also cause pitting or abrasions on your antique sterling silver.You can merely use a small amount of laundry detergent mixed with one half cup of warm water as your cleaning agent for doing a light cleaning for things like dust, dirt, or fingerprints. Then get a soft polishing cloth and give your antique sterling silver piece a nice polish. After you have completely air dried your cleaning implement, store it in a zip lock bag.
