After completing a couple of small repair jobs, I packed my materials in a cardboard box and loaded it in the backseat of my car. I didn't know that the can of W.S. "205" Hardener (with the mini-pump still installed) had tipped over and leaked through the cardboard and into the car upholstery. Now there's a gooey stain that I don't know how to treat. Any suggestions?
