I've just sparayed the gaps of my new door with spray foam and boy is there a mess. How does one get it off of a door (without scraping the paint) and off one's skin?

Most spray foam cans will have printed clearly on the instructions to wear gloves and eye protection when using the product. There is no good way to remove the foam from skin or anything else it comes in contact with, especially after it cures.

I use the Handi-Foam professional foam gun system, and one of their products is Handi-Foam cleaner which is a potent solvent. I assume it consists mainly of acetone or toulene and other nasty stuff. As I mentioned, though, the cleaner will only dissolve the liquid foam and will not dissolve polyurethane foam that has cured.

Your best bet at removing cured foam would be to use a plastic scraper and your fingernails. There is no good way to remove it from a painted surface once its cured, sorry. If you can touch up the paint, I'd suggest sanding it off with sandpaper then repaint.

 

I dribbled a drop on my stainless steel sink 10 years ago, and the drop is still there. I just wanted to see how long it would last. If you use solvents, use those with low flash points such as MEK (Methyl Ethyl Keytone), but be prepared to refinish whatever surface it touches. It is super sticky for a reason, and must be used carefully. Good luck.
