What can I use to clean a PCB?
ELS122:
I have a pcb that has some soda or something on it, it’s not flux.
I used naphtha to clean it and it worked really well but I ran out of it, it evaporated really fast.
So what can I use, I thought about using diesel, acetone (I think it will damage it) or gas, but gas works no better than diesel for cleaning and is super flammable so I won’t use that.
I wanted a rude username:
The usual suggestion is isopropyl alcohol, but ethyl alcohol works fine too. Wipe it with a brush (e.g. an old toothbrush).
However, if the dirt is actually some sugary residue like from soda pop, I would wash it in water first (preferably distilled water if your tap water has a high pH), then alcohol. Sugar is not really alcohol-soluble.
ELS122:
Well I would use isopropyl alcohol but either it has some really weird name or nobody just sells it where I live.
My water supply comes from underground (from a borehole? I think it’s called that..) anyway, it has a LOT of lime tho, is that bad for pcbs?
I wanted a rude username:
Maybe you can mail order it. The prices seem OK.
I would avoid using that water unless there was no other option. Your nearest supermarket probably sells distilled water. Sometimes it is in the clothes washing section, because people use for their clothes irons.

Yeah I know that there’s distilled water on my store, but the thing I can’t find is isopropyl alcohol.
Anyway it’s 2am so no stores are open, I wanted to clean this fast, it’s just a board with audio jacks and no other parts so I did the bad thing and just used warm water, hand soap, a toothbrush and then dryed it off with a towel the best I could, at least it’s conpletly clean of any soda now
