What is the best thing to use to clean solid sterling silver? ( .925 purity silver)?

In the context of the question it is both. An article that is homogeneous 925 fine Sterling Silver throughout can be hallmarked as such, and can correctly be described as solid silver. An article that is only plated with Sterling Silver is heterogeneous, it is a thin surface coating on a base metal article and would thus not be hallmarked 925, neither can it be described as solid silver. Britannia Silver (958 fine), Silver Dollars (800 fine) would be correctly described as solid silver. It is an article s structure of homogeneous silver alloy, not the exact fineness that counts.

NOOO i dont agree with her answer. First of all toothpaste is a harsh abrasive, mix that with baking soda and you have a real mess, not to mention a problem on your hands. Try this; Place a piece of aluminul foil shiny side up in a large glass baking dish. Place the cars directly on the foil. Mix together 2 tablespoons of baking soda, a half teaspoon of salt, and enough boiling water to cover the items. Pour the mixture slowly over the silver, making suire to keep the cars on the foil. Let sit for about half an hour and the silver should be clean.

Try this cleaning cloth. You have to buy in packages of 5 but they are only like $3 bucks a piece. I have ordered them and use them on everything, especially cleaning windows and clean mirrors. They are made out of tiny fibers. They are guaranteed not to scratch and all you do is rinse the cloth under water, wring it out and wipe ANY surface with no streaks or scratch. Use em over and over. I have not thrown one away yet!

I encourage you to try it out.

Grab a toothbrush and some toothpaste with baking soda - it works wonders!

i wonder if sterling silver polishing cloths would work ? they do really good on jewelry !
