Author	Topic: Cleaning Goblets Question
chase33 Posts: 362 Registered: Feb 2008	posted 02-24-2013 08:18 PM Hey All, I got some goblets yesterday (Gorham 272, pre-India and pre-Puerto Rico manufacture) and while polishing them today, I noticed that one has an oily like appearance on the surface. It doesn;t show in photos, so I can't post a pic. It looks like crazing you see on porcelain/china. Any idea as to the cuase and how to clean it? I polished with Wright's and washed with Dawn but it is still there. IP: Logged
Kimo Posts: 1627 Registered: Mar 2003	posted 02-24-2013 09:50 PM Sounds like it is a protective finish to prevent tarnish that was sprayed on such as laquer or plastic that is now old, a bit brittle and cracking from the metal expanding and contracting with temperature changes. IP: Logged

jersey Posts: 1203 Registered: Feb 2005	posted 02-25-2013 10:12 AM Hi! A suggestion from a friend of mine who Suggests lacquer thinner might work. I should have added this as well. Nail polish remover itself is oily ( in order to keep the cuticles healthy while removing the polish). Simple lacquer thinner has no oils added.

Scott Martin Forum Master Posts: 11520 Registered: Apr 93	posted 02-25-2013 10:36 AM A couple of questions: Are the goblets sterling or plate? if plate, what is the base metal? could the goblets be chrome plated? how wide is the crazing lines? Are the lines wide enough to let tarnish show? A little Egg yoke in a crack might tarnish a crack line? If it is a coating that is crazing then trying lacquer thinner or another solvent is an idea. Have you let the solvent stand or just wiped the solvent on and then off? IP: Logged
chase33 Posts: 362 Registered: Feb 2008	posted 02-25-2013 08:58 PM Scott, Sorry I forgot to mention they were sterling goblets (Gorham style 272), so no plating issues. I really don't think there is a lacquer coating. The surface just looks like oil-in-water. It is difficult to see unless you hold it up. Before polishing, there was an even "coating" of tarnish - no where did it look like some areas weren't tarnished. I left the nail polish remover on for a few minutes, then wiped it off. I feel like buffing would take care of the problem but I only want to do that as a last resort. IP: Logged
Scott Martin Forum Master Posts: 11520 Registered: Apr 93	posted 02-26-2013 05:09 PM Since they are sterling... another thought. Could the pattern you are seeing be condensation? If yes, then perhaps what caused the condensation had a high amount of salt or nitric acid which etched what looks like a coating? IP: Logged
