How to Get Rid of Water Stains on Unfinished Wood: Simple DIY Fixes That Work

Unfinished wood has a rustic charm that fits beautifully in many homes, but it also comes with a catch—it’s highly vulnerable to water damage. Whether it's a ring left by a forgotten glass or a spill that wasn't wiped up quickly enough, water stains can leave behind dark, blotchy marks that seem impossible to remove.

Don’t worry—there’s good news. You don’t have to replace or refinish the entire piece. With a few household items and a little patience, you can often erase water stains and bring your unfinished wood back to life. Let’s walk through some tried-and-true solutions.

What Causes Water Stains on Unfinished Wood?

Unlike sealed or finished wood, unfinished wood absorbs moisture quickly. When water seeps into the grain, it can leave behind a mark—often white or dark—depending on how long the moisture sat and what minerals were in it. The good news is most of these stains are treatable with simple, non-toxic methods.

What You'll Need

Here are some everyday items that work surprisingly well at lifting water stains:

  • Baking soda
  • White vinegar
  • Non-gel toothpaste
  • Olive oil or mineral oil
  • Mayonnaise or petroleum jelly
  • Fine-grit sandpaper (220+ grit)
  • Clean soft cloths
  • A hairdryer or an iron
  • You likely already have most of these in your kitchen or bathroom.

1. The Baking Soda Paste Trick

Best for: Light surface stains

Mix one tablespoon of baking soda with just enough water to form a paste. Using a soft cloth, rub the mixture gently into the stain, moving with the grain of the wood. After a few minutes, wipe it clean with a damp cloth and dry thoroughly. If the stain lingers, repeat the process once more.

2. White Vinegar Solution

Best for: Older or stubborn spots

Combine equal parts white vinegar and water. Dampen a cloth with the mixture, then gently rub the stained area, following the wood grain. Let the wood air-dry afterward. This method helps lift mineral deposits and is especially helpful for darker water marks.

3. Non-Gel Toothpaste

Best for: White rings or cloudy spots

Use a dab of plain white toothpaste (not the gel type) and rub it onto the stain with a soft cloth in a circular motion. After about a minute, wipe it off with a clean damp cloth and let it dry. Toothpaste acts as a mild abrasive and can lighten or eliminate white water marks.

4. Mayonnaise or Petroleum Jelly

Best for: Mild water rings or cloudiness

It might sound strange, but both mayonnaise and petroleum jelly contain oils that can displace trapped moisture. Dab a small amount on the stain and let it sit for a few hours—or overnight. Then simply wipe it off with a clean cloth and buff the area gently.

5. Hairdryer or Iron Method

Best for: Moisture that hasn’t fully set

If the water stain is recent, heat might help draw out the moisture. Use a hairdryer on low to medium heat and aim it a few inches from the stain, moving it around constantly. Alternatively, place a clean cotton cloth over the spot and lightly press a warm iron (no steam) for a few seconds. Lift and repeat until the stain fades.

6. Light Sanding for Deep Stains

Best for: Black or deeply set water marks

If home remedies don’t work, gentle sanding may be your best option. Use a fine-grit sandpaper and carefully sand the stained area, always moving with the grain. Wipe away dust with a dry cloth. You may need to recondition or seal the area afterward to restore color and protect the wood.

How to Prevent Future Stains on Unfinished Wood

Once you’ve restored your wood, you’ll want to avoid going through this again. Here’s how:

  • Use coasters or placemats to protect surfaces from spills.
  • Wipe up water immediately to prevent absorption.
  • Apply a wood sealer or wax finish if you’re open to adding a slight protective coat while maintaining a natural look.
  • Keep unfinished wood out of high-humidity areas, like bathrooms or basements.

Final Thoughts

Water stains may seem like the end of your beautiful unfinished wood piece, but in most cases, they’re just a temporary blemish. Whether you go the natural route with baking soda and vinegar or reach for a little mayo or a hairdryer, these simple DIY fixes can make a big difference.

So next time a careless spill leaves a mark, don’t panic—grab a few household items and take control. Your wood can look beautiful again in no time.
