How to Remove Black Water Stains

Black water stains result from iron reacting with wood furniture. The wood essentially rusts, causing unsightly black stains. They can be removed with some elbow grease and a simple solution, but the process is not recommended for antique furniture. If the furniture is not antique, this process will make it look new again.

Things You'll Need

• 80-grit sandpaper
• Hand sander
• Wood bleach
• Water
• Plastic container
• Old wooden spoon
• Scrub brush
• Vinegar
• Soft cloths
• Small box fan

Instructions

1. Remove any wood finish by sanding with the 80-grit sandpaper. You must remove the wood finish to get to the stain for removal.

2. Dissolve half a cup of wood bleach in a quart of warm water. Stir with a wooden spoon in a sturdy plastic container. Do not use the container or spoon for anything else, since wood bleach is toxic.

3. Apply a small spoonful of wood bleach to the stain. Spread it evenly over the stain with the brush and let it soak for three to five hours.

4. Wipe away the wood bleach and check if the stain is completely faded. If not, apply wood bleach again for half the time. Wipe away and rinse thoroughly.

5. Mix a cup of water with half a cup of white wine or apple cider vinegar (darker vinegars will stain the wood). Soak a soft cloth in the solution and apply to the previously stained area. This will neutralize the wood bleach.

6. Allow the area to dry for at least 24 hours before refinishing. Direct a small box fan, set on a high setting, at the damp spot to aid drying.
