how to clean vintage satinato glass?
I found a rather nice Rosenthal-Netter (still with tag) satinato glass vase today (evidently by Carlo Moretti, from some web research), and I'm wondering how to clean it (outside). Inside is another question altogether, since it's got about a 15" long 1" diameter neck...but I mean the satin exterior. It's not horrible, I'd just like it to look as nice as possible and remove any smoke layer that may have accumulated on it.
I've found one site and I'll link it, but I'm not sure it refers to my specific kind of glass.
Any thoughts, experiences, warnings, etc. would be most gratefully accepted. Haven't had time to take a pic yet, but here it is elsewhere:
Here is a link that might be useful: this is it exactly -- no chips or scratches, either :)
