Have you ever wondered whether there is a way to get black water stains out of your beautiful hardwood floors? Water stains ruin the appearance of hardwood, leaving dark and unpleasant marks, but is it possible to get rid of them without further damaging the wood?
Many people think black stains are permanent and that once your floor has been marked, there’s no way to get rid of it. That isn’t true, though; you might be able to restore the natural color and make your floor glossy, warm, and beautiful again.
Can you remove black water stains from hardwood floors? There are a few different tricks you can try to remove water stains from a hardwood floor. These stains are challenging to shift, but not impossible, and you should be able to get your floor looking good as new again with a bit of work. Some people find that using a small amount of wood bleach is effective, but baking soda, toothpaste, oil, or magic eraser may work too.
What are the Top Methods for Removing Black Water Stains from Hardwood Floors?
There are quite a few tricks you can try. You might find that a combination of these works better than any single one alone, but don’t try them all at once, or you may do further damage to the wood. You should try things like baking soda, wood bleach, magic eraser, salt and oil, toothpaste, or petroleum jelly.
Each of these needs to be applied in a different way, so in the below sections, we’re going to explore how to use them and whether they are likely to work. Remember, there is no guarantee that a product won’t further stain your floor, so you may wish to test each method in a small, inconspicuous area before applying it to a stain.

Applying Baking Soda
A lot of people have baking soda handy and it’s very useful for cleaning your wooden floors. To use it, you should mix a tablespoon of baking soda with a teaspoon of water. Thoroughly stir the two together, and then use a clean cloth to dab it onto the stain. Gently rub to work it into the stain and leave it for a few minutes to activate.
Check the stain after about 10 minutes and see whether the baking soda has worked. If not, it should be fine to apply some more of your baking soda paste and then leave it for a few hours or even overnight.
The following morning, wipe the paste away and see if the baking soda has removed the stains. If it hasn’t, you will probably need to try a different tactic, as a longer application is unlikely to make any difference.
Applying Wood Bleach
Wood bleach is another great option for getting rid of dark stains, although you should be careful because it can lighten the wood as it is taking out the stain. If you are going to use wood bleach, test it first, and do not use a large amount. Apply the bleach using a clean cloth, and wipe it away after a few minutes.
Some people do choose to use standard chlorine bleach on their wooden floors. This isn’t generally recommended, because it may damage the appearance of the floor. However, if you want to try it, you should dilute some bleach with water and then dip a toothbrush into it and lightly rub it into the stain, using circular motions.
When you’ve finished, make sure you wipe the bleach away.
Applying Magic Eraser
Magic eraser may work in some cases. To use this, gently buff the damaged area with the magic eraser, working in the same direction as the wood’s grain. It will likely take at least a few applications of buffing to strip the stain out of the floor, so be prepared to do this several times.
Once you have finished, you may need to polish the wood, depending on your floor.
Applying Salt and Oil
Salt and oil are another option you can try. Mix together one teaspoon of olive oil and one teaspoon of salt, and then gently rub this solution into the floor and leave it to sit for about 20 minutes. When you’ve finished, use a cotton cloth to buff the area and see if the stain has disappeared.
Applying Toothpaste
Toothpaste is also something many people have to hand, and it can lift stains. To try this, add a small blob of toothpaste to a clean, soft cloth and gently buff the wooden floor with it. The whitening agents in the toothpaste may help to pull the stain out of the wood and lighten it.
If you find the toothpaste isn’t effective on its own, consider adding some baking soda and rubbing with this. Don’t rub so hard that you scratch the floor, though.
Applying Petroleum Jelly
To use petroleum jelly, apply some to a clean cloth and rub it into the stain. Leave it for several hours or overnight, and then wipe up any residue the following day. See whether the stain has disappeared.
What If Nothing Works?
If none of the above methods are effective, you may need to sand the floor down and refinish it. The stain has probably got under the varnish or wax that protects your floor, and if the above products don’t work, stripping it back is probably your only option.
If you are going to do this, it’s a good idea to seek advice from an expert so you can make sure that the sanded area will match the rest of the floor. It may be challenging to get a good color match, but for deep black stains, this might be the only option.
Surface treatments can only do so much to remove water marks, especially if they are old.
Final Thoughts
As you can see, there are lots of great methods that will help you remove black water stains from a hardwood floor. Try the above in small quantities on an inconspicuous area first, and then swap to sanding and refinishing your floor if the water stains remain.
