Default Using acetone to clean PCBs?

I had been using isopropyl alcohol to clean flux off circuit boards. I didn't have any left so I tried some acetone, and it just ripped right through the stuff way easier than alcohol. Is this a good substance to use for this?

It's great as long as you don't mind frying some brain cells along the way.

Acetone works fine. It is obviously quite flammable so work in a well ventilated work area and you won't have to worry about flames or fried brain cells.

Also be aware that acetone is a solvent for many types of plastic!

Depends on the table, instead of anti-static mats I just use a grounded sheet of aluminum to assemble projects on. So no problem with acetone.

Health risks aside - as others mentioned, acetone is a pretty aggressive solvent. It may remove your silk-screen markings. It also softens some kinds of epoxy, but I don't know if that includes the types used in, e.g., FR-4 or CEM-3 materials.

I've been using this stuff for a while now . . .
4140-400G MG Chemicals Soldering Tools
and I still seem to have most of my brain cells.

My only complaint is that it's in an aerosol can, so I have to spray it into a tiny cup to dip a cotton swab, or brush into it.

ketone solvents can totally destroy some plastics - look up "crazing" - they really aren't safe for finished boards with lots of different type plastics in component casing and capacitor dielectrics
