You have a lot more patience than I do.

I would likely have rented a floor sander and wasted two or three sheets of sandpaper to just sand off the plastic and the glue. Then a fresh sheet of sandpaper for that nice looking wood.

I guess it all depends on how close you are to somewhere that rents that kind of stuff. If you are slightly North of the middle of nowhere ... you are most likely using the best possible method. :-)

Also, who is the person in the first picture that is wearing socks!!!! You must really hate that plastic floor. ;-)
