cleaning up white metal

Hello I was wondering if you have clues on cleaning white metal without bending it

"White metal" can mean several things.  It used to be a euphemism for lead, or lead alloy.  Lead is one of the most notoriously unstable of materials; it frequently degenerates into a white powder (aka "lead disease").  And sometimes it doesn't.  I've got some old Model Shipways "white metal" fittings in my workshop that I've had for twenty or thirty years, and they look as good as new.  I've also seen lead disease develop in less than a year.

Nowadays, due partly to government regulations, scarcely any hobby products have lead in them.  (Good riddance, as far as I'm concerned.)  I think what the manufacturers call "white metal" now is usually either britannia metal (a mixture of tin and copper) or pewter (which the dictionary in front of me describes as "any of numerous silver-gray alloys of in with various amounts of antimony, copper, and sometimes lead..." - but not lead any more, as I understand it).

Anyhow, there are various ways to clean it.  Several companies (e.g., Bluejacket) sell chemicals specifically for the purpose; they smell so much like vinegar that I suspect that's about what they are (and vinegar is an old-time remedy for the problem).  I like to rub larger parts with extra-fine steel wool, which will give it a polish almost like silver.  If the part has flash on it, you can trim it off with a sharp knife - as though it were plastic. 

One big virtue of modern "white metal" is its flexibility.  In most cases, if you do accidentally bend it you can bend it back.

Hope that helps a little.  Good luck.

For what it's worth, miniatures gamers clean the flash on their pewter figures with knives, much as Prof. Tilley suggests, but also with needle files and other tools.

Just remember when using that really sharp hobby knife to trim the flash off to always, always, always cut away from yourself.

And that's all I've got to say about that.
