*ESPN is a television sports network here in the USA.
I brought a set of silver spoons back 
from South Africa : a gift from my mom (that belonged to my grand-mother). While checking them out a little closer today, I noticed the letters EPNS-AI stamped on the back. Turns out the EPNS stands for electroplated nickel-silver and the AI stands for superior quality (the thickest layer of silver). So how to clean silverware (made of silver)? One way is to simply use a glass bowl lined with kitchen-grade aluminum foil, filled with hot water and ordinary salt. The electrochemical reaction (exchange of electrons between the aluminum and silver) will clean the tarnish. I also recall ‘Silvo’ that we used on occasion in my parents’ house – a mild liquid metal polish that originated in Britain at the turn of the last century.
