Caring for alloy Jewelry
Keep the silver away from substances that will cause tarnish. Anything that contains sulfur will cause jewelry to tarnish. To prevent this from happening, keep your silver away from things like:Sweat,Rubber and latex, Food items like mayonnaise, mustard, eggs, and onions,Wool,Lotions, creams, and beauty products
Take your jewelry off. Since there are so many things that can tarnish silver, it's a good idea to remove your jewelry when you go swimming in chlorinated water or do household chores (to keep the silver away from the chemicals). 
Wipe your jewelry clean with a silver polishing cloth before putting it into storage. Store it somewhere cool, dark, and dry. Humidity causes jewelry to tarnish faster, so the more you limit the humidity, the slower your jewelry will tarnish.
