That's why you DON'T get it on your skin any longer. Have to tell you though, when I was growing up I raced slot cars and we had some sticky stuff we put on the tires to make them hold better on the track. The only thing we could find to clean the tires was MEK, I used to buy it by the gallon

It's probably a lot harder to get M-E-K now than it was when we all grew up. Also, in that era before everything was found to cause cancer only in California, who cared about putting their hands in stuff or letting freon escape into the atmosphere. Acetone is probably weaker but easily available
