Polyurethane, outlines of a can, on floor

Q: My contractor installed laminated flooring; however, when he was applying polyurethane to┬áthe rail, he kept putting the can down and didn’t realize that the bottom of the can was leaving marks on the laminated flooring. Now I have marks of the shiny polyurethane, outline of the can, on my floor.

I don’t know what to get it off with, can you help?

A: Just an UNTESTED idea. Maybe a heat gun to soften the polyurethane, then wipe it down with a cloth and mineral spirits. Keep the cloth and mineral spirits away from the heat gun!
