I was just outside staining a piece of wood and got oil stain all over my hands. A bit of olive oil took it right off. These days, olive oil (or any cooking oil, really) is my first resort whenever I’ve got something staining, greasy, sticky or icky on my hands. I’m pretty sure we’ve written about this before–but it bears repeating: There’s no need to expose your skin to harsh chemicals like turpentine or paint thinner.
Usually oil alone will do the trick. For tough jobs you can grit up the oil with a few shakes of salt or baking soda. Sometimes a mix of oil and soap works better.
A sad but true story: As an art student, I was taught to thin my oil paint and clean my hands and brushes with turp. I often painted holding a turpentine dampened rag in one hand for hours on end. I wiped my turp soaked brushes on my jeans (’cause, you know, it looked cool). I cannot imagine how much turpentine I absorbed into my skin over the years. It was only much later that I discovered I could clean my brushes and hands just as effectively with oil.
Oil dissolves oil. Oil dissolves a lot of things. Keep it mind.
