My brilliant roomate stained a piece of wood to make a table about 5 months ago. She put a plastic sheet over the wooden floor of our living room and stained the table. For some reason, the stainer left a light film over the wooden floor, maybe eight or nine square feet. I rubbed a little Goo Gone on a small spot, and the film came off. I told her she could probably use Goo Gone to get the film off. She did nothing for the next 5 months, then, right before leaving the country for 2 months, just totally went wild with the Goo Gone and coated the whole area with the stuff. Now, the film is whiter, thicker, and looks horrible. My landlord, who lives below us, will not be happy if he sees this. I have tried scraping off the film -- it DOES come off, but with much effort. I don't know if scraping will be the best method to remove it. I've applied Isoprophyl rubbing alcohol (70%) to small areas and then used soft sandpaper. The film has sort of comes off in these spots, but sometimes a less spotty, smoother white film/sheen appears. A friend said the floor is "stripped" and we're screwed, but I think this can be taken care of with sandpaper and the right kind of liquid solution... any suggestions?
