I tried the tinfoil in a pan with baking soda - didn't work.
I tried toothpaste - didn't work.
I resorted to good old elbow grease with a silver cleaning cloth and it is now sparkling like new - well, almost.
Then I spent way too much time on You Tube listening to songs for the father/bride dance at the wedding. Since Leo is stuck in the 60s, he suggested Procol Harum's "A Whiter Shade of Pale" - that was his only suggestion. I'm not sure this is an appropriate choice however as every time he hears it, all I hear about is the summer he was 18 and working in Wasaga Beach - I don't think we want to go there! He used to really be into music but his car radio is constantly tuned to the 60s station on Cirrius. All my attempts to get him listening to music from this century have failed dismally.
Maybe one of these days I'll actually have something quilty to report - but don't hold your breath.
