Hardwood flooring continues to be the most popular flooring option available. It not only adds beauty to your home but also adds value.
Which makes it a real bummer when you see that your floor is turning black or has black dots all over it. Luckily, in most cases, this is a problem you can fix.
Key Takeaways:
Your wood floor could be turning black due to either moisture damage or an adverse reaction to metal that may be resting on it. Excess moisture is treatable with hydrogen peroxide or a wood stain treater. Metal spots need tannin spot neutralizers, which you can treat and leave for an hour before wiping dry. In dire cases, you may need to refinish the wood.
Top Two Reason Your Wood Floor is Turning Black
There are two reasons your wood floors are turning black. First, there’s been moisture damage caused by a spill, urine, or flooding that has caused your wood floors to mold. Secondly, your floor has reacted to metal sitting on it. Either way, the affected floorboards should be treated or replaced.
Why Your Wood Floor is Turning Black
Black Mold Spots in Your Floor from Water Damage
The most common reason for a hardwood floor to turn black is because it’s growing mold caused by excess moisture. You can confirm this if the black spots on your floor are in areas where there have been flooding, spills, or urine messes.
There are a few ways you can go about removing black spots caused by excess moisture.
Here are two of the most popular:
Treat the spots with hydrogen peroxide – If you have light-colored flooring, using peroxide to bleach the stains is a viable choice. (However, before you do this, you need to do a spot check to ensure no bad reactions.)
Use a wood stain treater – A product explicitly formulated for wood stains (especially those for urine) may be able to lift the black marks. A popular product to try is Nature’s Miracle Hardwood Floor Cleaner.
Black Spots Caused By Metal
If you have oak floors, you may notice black spots where metal or water, even in small amounts, has come into contact with your floor. (Like metal table legs sitting in place for an extended time, for example.)
This happens because oak flooring is very tannic, and the metal and water cause a chemical reaction, creating black marks.
How to treat black spots caused by metal:
If you think you’re dealing with black spots caused by a chemical reaction, you can treat it with a tannin spot neutralizer. To use a product like this, you’ll need to treat the area with the tannin neutralizer, let it sit for 60 minutes, and wipe dry. Afterward, you’ll need to reapply the topcoat to the places you’ve treated.
What to Do If You Can’t Get the Black Marks Out of Your Floor
If you tried treating the black marks on your floors with a stain remover or peroxide and didn’t have luck, your next best option is to replace those floorboards or sand out the stains and have those areas refinished.
If the stain is large, you may need to have your entire wood floors refinished.
Frequently Asked Questions
Does water stain hardwood floors?
Yes, water can stain hardwood floors. Even worse, if you see black on your hardwoods after they were exposed to moisture, you’re probably dealing with mold.
What causes white spots on hardwood floors?
White spots on hardwood floors are usually caused by heat or by spilling a hot liquid on them. You may be able to remove these spots by dabbing them with hydrogen peroxide or using a wood stain remover.
How do you remove brown water stains from hardwood flooring?
You can remove brown water stains from your hardwood the same way you would with black stains. Start by treating the spots with hydrogen peroxide or a wood stain remover. If that doesn’t work, you’ll need to replace the boards with stains or sand and refinish them.
Conclusion
If you’re wondering why your wood floor is turning black, the most common answer is that moisture has seeped into your floor, causing black mold. However, if the black spots are small and still relatively new, you may be able to remove them with a stain remover or peroxide.
For larger, set in black spots, you may need to replace your flooring or have it refinished.
