Get some of that Permatex brand orange oil base hand cleaner, dillute it some, and apply liberally. Perhaps even radically. It works well for oil spots on clothes as well, rub it in just before laundering. I would imagine there might be some good oil to apply afterwards to prevent excess drying that would not be an irritant -- olive or mineral oil maybe?

I'm pretty sure anti-freeze is a lot worse than the various oils, though they are to be desired internally either of course.

I'll have to agree with Palangi here, a vet consultaion might be a good idea.
