my opinion is that you will just have to use old fashion elbow grease and scrape it off. go to home depot or loews and buy you a flat blade scraper with a long handle and scrape as much as you can get off ...then what is left will have to be sanded down with a course sandpaper with a floor sander made for hardwood floors. hope this helps. by the way Bob V. never replies personally to these questions. others may be aware some other products to help but I dont know of any. Is the glue hard dry or still gooey?
