International Silver Co EGW&S. Tea Set Teapot Sugar and Creamer

Description

In this listing I have International Silver Co
EGW&S.
Tea Set  Teapot Sugar and Creamer.  When I bought the item it was "taped" together and the tape sticky residual is still on the items.  I am afraid if I use more than a cloth and water I may damage the piece, as I really don't know how the clean this type of item. Preowned.  Very tarnished and really needs a very good cleaning and also has lots of tape sticker residual.  The item is monogramed and I am not sure what the letters are.  Bad eyes on my part but also don't want to clean in case I cause damage.   If there was a lid to the sugar I do not have it.  Please email any questions.
I reserve the right to send by Federal Express as I find the the USPS Priority boxes give me limited space for larger items.
