To help screws screw in more easily, push them into a bar of hand soap before inserting.

If screws become loose and is no longer holding firm, saturate a cotton ball with Elmer's glue. Push the entire cotton ball into the hole. Allow dry at least 24 hours and reinsert the screw gently with a screw driver.

To prevent screws from coming loose, put a drop or two of clear nail polish into the hole before you finish tightening the screw.
