I have silver tone fashion jewelry that with only a few times of wearing it, the silver tone begins to rub off. I know they will not last a lifetime, but I can only wear them a few times before they look old and faded. I know this happens because of the oils on my skin and products I use. My question is the following, is there any type of silver tone or even sterling silver finish liquid or spray or even paint that you can brush on to "refinish" these pieces and make them look new again? Thank you!
