Things You Will Need
- Paste wax for wood floors
- Fine (4/0) steel wool
- Camphorated oil
- Clean, lint free cloths
- Dark spots on a wood floor are often caused by an alkaline substance, such as pet urine. To remove these spots, first dab the area with a clean cloth dipped in mineral spirits to remove solvent-based waxes (newer floors with polyurethane finishes aren't generally waxed). Ventilate the room and don't use mineral spirits around sparks or flames. Pour 1/4 cup white vinegar on the stain and wait five minutes. Wipe the vinegar up. The acid in the vinegar may neutralize the alkaline stain, causing it to disappear, according to the Michigan State University Extension.
- Wipe up spills immediately to prevent water damage, which can cause wood floors to warp and swell, in addition to staining or ruining the finish.
