Extremely dangerous stuff, and produces phosgene gas.... It is used in VERY WEAK solution, with voltage, to dissolve and plate gold and Platinum.... also a great cleaning solution with probably 1/1000th of the strength that you used...say no more. Obviously, anytime this stuff is used, you need ventilation that roars. You are a very lucky person. I would go find the idiot that sold you that and stop him before he kills someone.

The smell of rotten eggs means usually hydrogen sulphide, so I suppose, you have had a quite heavy liquid to clean the mets. Well, natural product anyway, no doubt...;- If the stuff has been a mixture of hydrochlorid acide and sulphuric=20 acid, you have been lucky you didn=B4t hurt yourselves, huh. If you pour water / alcohol to this heavy acid, the reaction may be very violent. But the mixture sure etches irons... take care, pekka s Adam Hupe wrote: >Dear List Members, > >We had a pretty strange thing happen in our shop today.
