How can I effectively unglue wood glue from a surface?

To effectively unglue wood glue from a surface, you can use a few methods. One way is to apply heat using a hairdryer or heat gun to soften the glue, then scrape it off with a putty knife. Another method is to use a solvent like acetone or vinegar to dissolve the glue. Be sure to test the solvent on a small, inconspicuous area first to ensure it doesn't damage the surface.
