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?


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.

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.

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

Actually acetone is much lower on the bad solvent list than several other readily available ones. OTOH I have had it dissolve PS caps from some makers and remove markings from many things.

A funny story. While a student at MIT our group bought a 17x22 printing press at auction that had been abandoned after its last job with all the ink dried on everything. We plugged the darkroom sink got some WWII gas masks and checked 20 gal of acetone out of lab supplies and cleaned the lot sending the results down the drain afterwards. Times have changed.

I've used acetone over the years to clean several things. Just take simple precautions, particularly good ventilation and all will be well. It didn't fry any brain cells of mine. They were fried before I emerged into this world. So didn't need to worry about that. However super clever people might need to be cautious ! 🙂

TCE ( Tri chloro ethylene ) also cleans pcbs's very well. Is that why I'm already senile ?:scratch:
 
Acetone on a circuit board? No way!

Definitely don't use acetone. I describe in full detail here - don't clean PCB with acetone

But basically acetone is a strong chemical that can melt some plastics. That article even has before añd after images it's crazy.

I would still to something less abrasive like rubbing alcohol or just water if it's not too bad.

Some people put it in their dishwasher put I've never done that and won't recommend it lol, but you can try it if you want.

Good luck though

Wish you the best
