I'm no expert, but goof-off, a sharp stainless putty knife or plastic
spatula, and one of those mesh ball kitchen scrubby things comes to mind. Do
not use steel wool or a wirebrush. Keep it all as dry as you can. You may be
able to get away w/o a full sand and refinish, but expect to do a light
refinish, at least in the traffic areas or where grit fltered through the
carpet, and a heavy cleaning and waxing all over. Hopefully they put the
tape over intact finish, and not the worn-through spots. (Hey, I have seen
people put w/w over brand new hardwood before, because w/w is what rich
people had.)
