The kiddush cup that was used thruough out the year should not be used as it was used with wine that was used for chometz. Best to buy a new one even if it is not silver (and than you can save the new one for all years)

koshering my silver
Do i need to do anything special to the silver we use during the year, do I need to kosher the kidish cup?
