This afternoon while spray painting some boxes (for Operation Christmas Child - new way to decorate them rather than wrapping them), I got spray paint all over my hands. Soap and water, even lots of soap, just made them even gunkier. I knew Mike would not be happy if I went out to his garage and started digging around for his gasoline can. Nor was I too crazy about that idea myself.
Then I remembered all those years of teaching solutions in chemistry and physical science. Like dissolves like. We even did a lab on that, using oil and water to try to dissolve different things and see how a polar solvent (water) dissolve polar solutes (salt, sugar, etc.) and a nonpolar solvent (oil) dissolves nonpolar solutes (wax, vitamin E, etc.)
So - maybe vegetable oil would work? I got it down and liberally applied it to my hands. It worked.
Who knows - I may be the last to discover that vegetable oil gets off spray paint. But at least my hands are not gunky, or stained red and green, any more.
