Q: One visitor asked, "I have a 1/2 inch burnt mark from a cigarette on my hardwood floor, how can I remove it? The wood was already stained and had polyurethene on it when installed."

A: Depending how deep the burn is, you can perhaps rub the burn out with fine sand paper. Stain the spot and when dry (make sure you lightly abrade the entire board when sanding out the burn) re coat the entire board with a thin coat of finish.
