Anti-tarnish strips for the jewelry and precious metal industries are primarily made for storing and shipping the items in order to ensure that the silver or other precious metal does not tarnish before it reaches the retailer or while in storage at the retailer. These products should be easy to use, non-toxic and non-abrasive.
I love to collect silver. I even hang it on the wall. But when it starts to look like this, I know what to do. Here's how I clean my silver: I get my cotton balls out, put some Tarn-X on them, rub my silver until it shines. I rinse it well.
