I had to clean up the interior surface of a villa's front door. Suffice it to say it took some elbow grease, but now, even though the door looks clean it feels sticky to the touch. Other surfaces that were not dirty (and which I did not clean!) do not feel sticky, they feel smooth. Has anyone got suggestions on how to get rid of the sticky surface? Furniture polish? Wax? I just thought this might have happened to someone else before....
