Removing residue from carpet padding

Q: I removed carpeting that I have shampooed in the past. I am assuming that when I did this the carpet padding became damp, thus causing some of the padding to stick to the hardwood. I was able to remove the padding, but it left behind a residue. So, my hardwood looks spotty, where I cleaned the padding off. How would you suggest I (try) to remove this residue?

A: Mineral spirits and elbow grease should help to soften it up.

Similar Q: I pulled up wall-to-wall carpet in a bedroom, and the entrance area has blotches of film from padding. What is the best way to clean this? The house was built in 1979, so it is a waxed wood floor.

A: Scrape off as much of the underpad possible with a putty knife. Rub off the rest with fine steel wool dampened in mineral spirits and dry. Apply a little wax to the area, if wax is the finish currently on the floor.
