Walnut milk stains on wood can be stubborn, but with the right approach, you can restore your furniture or flooring to its original condition. Here’s a step-by-step guide to effectively remove walnut milk stains from wood:

1. Blot Immediately: Use a clean, dry cloth to gently blot the spill. Avoid rubbing, as this can push the stain deeper into the wood grain.

2. Mild Soap Solution: Mix a few drops of mild dish soap with warm water. Dampen a soft cloth with the solution and gently wipe the stained area. Rinse with a damp cloth and dry thoroughly.

3. Baking Soda Paste: For tougher stains, make a paste of baking soda and water. Apply it to the stain, let it sit for 5-10 minutes, then wipe away with a damp cloth.

4. White Vinegar: Dilute white vinegar with water (1:1 ratio) and dab the stain lightly. Vinegar helps break down the milk proteins without damaging the wood.

5. Mineral Spirits (For Finished Wood): If the stain persists, apply a small amount of mineral spirits to a cloth and gently rub the area. Test on an inconspicuous spot first.

6. Polish and Protect: After cleaning, apply a wood polish or conditioner to restore shine and protect the surface.

Always test cleaning solutions on a hidden area first to ensure they don’t damage the wood finish. For deep or old stains, consider consulting a professional wood cleaner.
