How to Remove burn marks from wood furniture
Success of these treatments really depends on how far into the finish or into the wood the burn goes.
Treatment:
1. If the burn mark is only as deep as the finish, wrap a small piece of very fine steel wool around your finger and gently rub the scorched area. Polish and wax the area.
2. If the burn mark has blisters in the center, hold a knifeblade at a right angle to the burn and carefully scrape the burned area using side-to-side motions. Once all the burned area is removed, rub a piece of steel wool on the spot until the area is smooth. Brush the dust a way to see if any finish remains. If so, polish and wax the area to restore luster.
3. If you have scraped into the wood, you need to build up the cavity that now exists. Apply thin coats of varnish or shellac with a small artist's brush, allowing each coat to dry before applying the next one. Once the area matches the surrounding surface, rub it carefully with a piece of steel wool dipped into paste wax. Blend the area by rubbing parallel to the wood grain. Polish and wax the area.
