Please help! Cleaning silverplate.
We had a brunch on Monday after my daughter's naming and I put coffee in my brand new Silver Coffee Urn. The coffee was in it from 10am-3pm I dumped it out and cleaned it and it smelled horrible. I let it air out on until Tuesday evening and it still smelled. I then put baking soda in the bottom of the urn and just cleaned it out but it still smells. How do I get the smell out without ruining the urn? It is a silverplate, Elegance Silver 25 cup coffee urn. Thank you in advance.
