1. When working with business oriented jewelry cleaners, be sure any stone in the jewelry to be cleaned can withstand the chemicals in the cleaner (consider cleaner's label), avoid the use of a chemical cleaner for anyone who is doubtful. Types of stones to watch out for in this class of cleaners use include: pearls, opals, coral, turquoise, and much more 

2. Virtually any jewelry that can't stand business cleaning liquid shouldn't be cleaned with Ammonia alternative 

3. Hardly ever use toothpaste to clean your silver jewelry as a lot of articles are suggesting, toothpaste is abrasive and will cause scratches around the jewelry.Finally, bear in mind, because you use, and clean your gold or silver jewelry, small amounts of tarnish will begin to give the jewelry old fashioned appearance and feel. Carefully and good storage, your jewelry mayoffer you years of enjoyment.
