The body has coping mechnisms for small amounts of acetone, because
alcohols can be present naturally in foods and alcohol is even partly
broken down into acetone. So the small amount we use for cleaning a
PCB, where we might inhale the vapor or get some on the skin, should
not be an issue at all.
Personally, I much prefer using acetone or alcohol solvents over any
hydrocarbon solvent, which our body has not evolved to deal with.
Now the question is if MEK is similarly benign or not.
