I did a really stupid thing. Well I forgot I had some of my tiffany silver pieces on and went for a swim in the pool. When I came out I noticed they were all greyish and looked dull. At first I was like WTF? Then realized it was the chlorine in the pool. Is this fixable? I was thinking about sending them in to Tiffanys to get them 'fixed', not even knowing if it could be done. Then I remembered reading a post using some kind of cleaning polish for silver? Will this work? I read that it would work to make them shinier, but in my case they got really tarnished pretty badly. Where would this be available? Any particular kind that works best? Any suggestions would be greatly appreciated. TIA!
