It dismays me no end to hear anyone suggesting acetone is a good
material for anything. I had a beloved professor who developed aplastic
anemia in large part from using acetone when he did lithography. He had
always done everything right- good ventilation, heavy duty industrial
gloves and rubber apron, ventilation mask. In spite of all of this he
woke up one morning bleeding from his ears and eyes. It took years for
him to recover.
Everyone's tolerance for the chemical is different. For some people is
it a relatively short period of time, for others it can be decades, you
just don't know.We owe it to ourselves, our loved ones and our students
to find/create methods with materials that put no person at risk.

Some folks are allergic to peanuts and have died from eating them ... some are allergic to coconut ... some have bad reactions to shellfish ... some are allergic to penicillin ... and so on and so on. Certainly individuals vary widely in their responses ... and it pays to listen carefully to your own body.
People have been stabbed to death with carving knives and chisels ... many more artists have been severely injured or killed in automobile accidents than by solvents ... What conclusions should we draw???
At this stage of science, the indications are that acetone is one of the safest solvents. That does not mean it is suitable for everyone, nor does it mean that no one has ever been harmed by it, nor does it mean that one should bathe in it. Prudence is of course indicated, as with everything we use. But to issue a blanket condemnation because you know someone who was harmed by it is perhaps a bit too hasty.
