Steps on how to remove black stains from hardwood floors
When your hardwood floor ends up with black stains, you can readily get rid of them by following these steps on how to remove black stains from hardwood floors.
- Cleaning the spot. Soak a ball of fine steel wool in a mineral spirit and rub the stained area. An alternative is soaking it in lemon oil. Allow the mineral spirits to dry. If you are using lemon oil, use enough oil to prevent scratching the floor. Rub gently to prevent scratching the wood.
- Sanding the black marks. If the wooden floor is not sealed, finished, or polished, you can sand-off until the stain vanishes. Use back-and-forth strokes until the stain is gone. Wipe away the wood dust using a dry microfiber cloth or use a vacuum cleaner. For polished, sealed, and finished wood, you can sand the black stains out. Just make sure that you will rub the sandpaper in the direction of the wood grain. Feather the edges of the sanded area using a ball of steel wool to ensure they blend well with the original finish. Apply wood varnish, wax, or lacquer as a top coat to match with the original finish.
- Bleach the stain. The method that involves using wood bleach can also remove stubborn black stains from the wooden floor. These products work by lightening the hardwood floor and helps remove the stains. Aside from the commercially available solutions, there are also homemade options available such as the following:
- Chlorine. Ideally used to get rid of blood, ink, and food stains.
- White vinegar. This works as a disinfectant and deodorizer that is good for both stains and odor on your hardwood floor. Mix a cup of white vinegar with a cup of warm water. Scrub the site until the stain vanishes and pat dry.
- Hydrogen peroxide. Saturate a clean cloth with hydrogen peroxide. Let it sit overnight or at least 8 hours or longer until the stain vanishes. If the stained area bleaches, consider sanding and finishing the floor.
- Baking soda. Mix vinegar with baking soda to create a paste. Dab the paste on the site and allow it to dry fully. Use a soft cloth to wipe the paste away.
- Oxalic acid. This works best for stubborn aged stains. Once the bleaching process is over, use a neutralizer before sanding and refinishing the floor.
- Staining the site. Sand the bleached area first using fine-grit sandpaper. Use a vacuum cleaner to remove the wood dust. Choose a stain that matches your floor and apply it with a rag. Let it sit for up to 15 minutes and wipe away to remove the excess.
- Applying a new finish. Once the floor completely dries up, apply polyurethane. You can choose your preferred wax on the treated area.
