Want Pencil Lines Erased Without a Trace? Try Alcohol

The next time you make a pencil mark that you don't want to sand away or remove with an eraser, try denatured alcohol. Soak the corner of a rag in alcohol, and rub the rag across the pencil line. The alcohol will remove the pencil mark and not leave any residue to affect the finish.
