I use Acetone for aluminum final prep before Tig welding, never a problem. |

We use acetone a lot in the aviation maintenance world on aluminum. Just don't use it on plastics.

Thank you. My statement was too broad, I see. Quote HistoryQuoted:
Quoted:
Organometallic chemistry is a fascinating topic 
There's a wide spectrum of substances covered by "metal" and "organic solvent". For example, alkali metals can dissolve in tetrahydrofuran. Francois Grignard was awarded the Nobel Prize in 1912 for the eponymous reaction involving organomagnesium compounds. So yes it's possible but gun owners are largely safe from this phenomenon My statement was too broad, I see. I hope that came across

My reply was intended to be in the spirit of "there's a lot of interesting science out there that some arfcommers might not know about", not "haha, you're wrong". I hope that came across Thank you again. |

Just as an aside, thanks to a set of changes a while back, we can now write things such as H2O2 correctly.
Not too many seem to have noticed it. |

Acetone doesnt. Simple green will though, after long enough exposure. Degrease, or degrees?

It will remove the lanolin from rolled aluminum, but that's it.
Now try mercury with it on a freshly acid cleaned surface. Now that is amazing the watch.  Aluminum and Mercury |

I don't see how an organic solvent can react with a metal, but I await an opinion from some sort of either a chemist or a metallurgist.

I looked less Cro-Magnon for a week until the hair grew back.
