Do you prefer your sandwiches wrapped using transparent plastic, wax paper, or aluminium foil?
Tarnish is part of the appeal I think.plus it makes the cups more valuable.are you talking about metal cups? If so, try toothpaste or baking soda(((angel))
I use Wright's Silver CreamYou can purchase this at most grocery storesJust apply this cream to your silver and the tarnish can be rubbed off with a soft cloth.
Get a jar of silver polishThat's the best thingCLR is a bad ideaIt's a mild acid, and can (and may already have) etch your silverGood luck.
In the context of the question it is bothAn article that is homogeneous 925 fine Sterling Silver throughout can be hallmarked as such, and can correctly be described as solid silverAn 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 silverBritannia Silver (958 fine), Silver Dollars (800 fine) would be correctly described as solid silverIt is an article s structure of homogeneous silver alloy, not the exact fineness that counts.
transparent plastic (sandwhich bag -_- what's with the big words, dictionary ?) i think wax paper's weirdand i don't have a problem with sandwiches wrapped in aluminium foil, but i'd rather use a sandwich bag.
