Question:
We recently acquired an International Silver serving platter and after cleaning with silver polish, there are splotches of light pink that appears to be a stain of some kind. Can this removed or is it possible that we have scrubbed below the silver plate? Thank you.


Replies:
Without actually seeing the tray, I suspect that you are seeing the copper peeking through the silver plate. By now, those pink spots have probably turned a more familiar orange, or brownish orange (more the color of pennies) if this is the case. If you purchased this item secondhand, it could have been showing these spots when previous owner last cleaned it. If the item was recently acquired new, you may have some recourse under warranty. Always be sure to follow label instructions and to completely rinse and remove polishing agents from silver and plated pieces following cleaning as these cleaning/polishing chemicals can often accelerate surface decay when left in place for extended periods of time.
