Talk:Thiourea

Silver Dip
I have just bought a jar of silver dip (mentioned as TarnX in the article - presumably a trade name on the American side of the Atlantic) - a solution used to clean sulphide tarnish off silver. I was curious about the active ingredient, given as thiourea. This would appear to be a significant use for thiourea, for the public at least, if not for industry. Could someone add a few lines to this article about what reaction is going on to clean the silver, and why, if you leave the article in the dip too long, it goes blacker than it started! I should be most appreciative. --King Hildebrand 16:15, 28 August 2007 (UTC)

I, too, would like to know the answer to King Hildebrand's question.

The name Silver Dip is used in England, too, where I used it for many decades cleaning antiques.

The link for TarnX near the end of the Applications section loops back to the beginning of Thiourea where it has "TarnX redirects here". Perhaps an entry for Silver Dip would be useful, redirecting readers here. John C Kay (talk) 00:04, 3 August 2010 (UTC)

Thiourea named as antu ?
I think, that ANTU = alpha-naphthylthiourea —Preceding unsigned comment added by 188.246.98.226 (talk) 19:50, 21 December 2009 (UTC)
 * That's right, see ANTU --FK1954 (talk) 06:56, 19 January 2010 (UTC)
