Default Using Acetone On Metal ?

Hi,

New here and I have a question about using acetone. I just started learning how to MIG weld aluminum.

Is acetone safe to use to clean aluminum ?, and other metal if I need to ?

Is this what I need ?

Sorry if its a stupid question. I just want to make sure the acetone is safe to use on something to be welded.

I know the dangers of using brake cleaner. It can kill you and I never use it.

Thank you!

That's what we use for most metals. Just make sure you let it dry and get the rags and can a safe distance away from your welding area.

I'll keep the rags & can away from any welding.

+1 on acetone for cleaning metal for welding

But be careful about using it on plastic. It will ruin the surface of many plastics.

It is also better to not let it get on your skin. It is a known carcinogen,

It would depend on what your welding and for whom. The defense contractor welders I know, said they are forbidden to use any chemical cleaning agents, as they can contaminate the weld. Depend on what you are doing that may not be a concern.

FWIW, I use lacquer thinner more than acetone for this purpose because it's a mixture of both polar and non-polar solvents...seems to cut more types of crud.

I've found this to be true to.. Seems to cut thru greases and such faster..

But for normal cleaning of filler rod or New alum I use acetone.

be sure and wear rubber/nitrile gloves.
