||I buy secondhand silverplated cutlery, challah plates, and kiddush cups for gifts. They are from ebay, or estate sales, and I have no way of knowing they are kosher and can assume they are not. Many times they are very tarnished. what is the correct procedure?
to kasher first, or to clean off the tarnish first, or does it not matter?
do Kiddush cups really not need to be kashered, as per your website?
to clean off tarnish I need to polish with cleaning material and rinse off with hot water in a sink. Or I can - if the material is flat enough, put it into a disposable aluminum pan with baking soda and boiling water, then throw out the pan.
we are Ashkenazi, but sometimes I want to buy these as gifts for sefardim.
