One may remove glue from wood furniture by either buffing away the glue using acetone, nail polish, an orange-based cleaner, WD-40, vegetable oil or a solution containing benzene or naphtha, or by carefully sanding the glue away. Any cleaning solution should be tested on an inconspicuous portion of the furniture to see how the wood reacts to it before being used.
Begin by placing a small amount of cleaning solution on a cotton ball or rag. Apply the solution directly to the glue. Gently rub the solution into the glue. Then, use an extremely dull scraper or an old credit card to scrape the softened glue from the wood. Make sure to work from the outer edges inward to avoid damaging the wood.
If glue still resides on the wood after the solution is applied, very carefully sand away the glue. Begin by framing the glue with painter's tape to avoid damaging the wood around the glue. Use 600-grit sandpaper, and gently sand down the glue. Once there is only a small portion of glue left, switch to a piece of 1,200-grit sandpaper to sand down the glue further. The finer-grit sandpaper ensures that the furniture is not damaged while the glue is being ground down flush with the wood.
