Removing mold from wood floors

It is a widespread problem for especially new house owners. Today buildings are constructed in fast pace and airtight. Moisture doesn’t have appropriate time to dry out and escape. When moisture can’t escape mold occurs. It is not a pleasant situation, and it may cause many allergic reactions if not reacted fast.

If mold is in a small area, then you can remove it yourself, but if the situation is worse and molds are covering a large area of the hardwood floors, I recommend calling professionals. They will bring all the advanced equipment to remove it from your house.

If the problem is not that big, and you don’t want to spend hundreds of dollars, you can follow these simple instructions below.

How to Remove Surface Mold from Wood Floors

Surface Mold as the name suggests affects the surface of the wooden floors. It usually leaves a stain on the floor. Removing it is pretty straightforward just follow below steps and safety measures.

Don’t try to fix mold on your hardwood floors if you don’t have proper protection. Mold causes allergies and other health issues.

2. Select Proper Mold Cleaner and remove it

There are few cleaner who can do job well. This are my personal three best options. Later on I will recommend also alternative methods as well.

  1. Mold Armor
  2. Concrobium 25326
  3. Chlorine bleach

With all three options it is adviced to leave sollution on the mold for 10 minutes, then take a rag and wipe it off from the wood. If using bleach, use some old rag and throw it away after job is done. Bleach contains really harsh chemicals and it’s not safe for animals.

Lucky there are some Cleaners safe for us and animals, very effective and without harsh chemicals.

Mold Armor

Mold Armor is really a beast. It health wise something between Bleach and Concrobium spray. Let’s be honest – you need to kill all the mold on your wood floor instantly. If they get lighter because of harsh chemicals you will refinish them after but at least you removed it completely. Worst thing would be, mold penetrating threw your floors and becoming ingrained type.

Alternative Methods Cleaning Surface Mold

1. Using Vinegar

Vinegar is a mild acid that will generally kill 82% of mold species. Now adding Baking Soda and mixing with the vinegar can usually kill all off the surface mold. Make a spray bottle and than spray like you would with above paid cleaner version.

2. 3% Hydrogen Peroxide

Take 3% hydrogen peroxide pour it in to a spray bottle. You can apply / spray it same as with other cleaaners directly to your floors. Be careful – to to combine or mix it with Vinegar. Mixing it together would create corrosive substance known as peracetic acid who would definitely ruin your precious hardwood floors.

3. Using Borax with Water

Mix one cup of Borax and one cup of water in a spray bottle and spray that mixture on mold infected place. Borax is natural, and it has antimicrobial quality.

4. Tea tree Oil

Tea tree oil can be effective natural cleaning sollution as well. You need as with most of cleaners a spray bottle and distilled water.

Take 1 cup of water and add one teaspoon of tea tree oil, mix it up, and your mold killer is ready.

How to Remove Ingrained Mold From Wood Floors

Ingrained mold penetrates the wood and causes much more significant, harder, and expensive to remove damage. In most cases, there are professionals needed to restore your floors in good shape. Sometimes the mold is very deep, and you will need to change part of our floors. They are too damaged to be safe, and you will prevent mold from spreading as well.

With ingrained mold this steps should be followed:

1. Testing Depth

The first thing you want to do before removing ingrained mold is to test the affected area because sometimes you don’t know how deep did mold penetrate in to the wood. 

To do this, use a sharp tool and press it into the affected area. If the sharp tool is going deep into the wood, and it feels soft, then the problem is not that simple. 

If Wood feels spongy, then it is rotten and can’t be saved.

2. Dry your Wood Floors

Mold spread when moisture is present so we will need to get rid of it before going forward.

  1. Bring a drying fan or fans and direct them toward the infected area.
  2. Wear a mask when you are in the space where mold is present.
  3. Turn your fans on and keep them on for several hours.
  4. Keep all of the windows open and put a box fan, like this on Amazon on one of the windows and face it to the outside of a window and turn it on. It will keep throwing mold infected air outside of your house.
This is is necessary step when removing ingrained mold

3. Remove Upper Layer

To remove the top layer, you will need the following tools.

The first start with 100 grit sandpaper then switch to 220 grit sandpaper to eliminate the mold. Make sure you sand the affected area in a circular motion. When mold is removed, use 220 grit to make the area smooth.

4. Spray Cleaner

Even id you have removed the mold affected area thoroughly, there are still some mold spores left on the affected area. You can’t see them with your eyes. 

Mold can spread again from this area, so what you need to do is spray a cleaner that I mentioned before or other similar solution.

5. Cut Out Wooden floor that can’t be saved

If mold spread deeply and already rotten the wood and you can’t save that part, cut it out. After replace it with new part of hardwood floors

6. Restore Wood Color

When we remove ingrained mold from your wooden floor, it will leave a stain, which will make the floor look uneven. All you have to do is to buy a Wood finish that matches the color of your original floor color.

7. Use Vacuum

Use a vacuum to clean your floors after. Make sure you toss immediately the infected parts in a trash bag.

After vacuuming, clean your vacuum with mold cleaner spray and make sure there is no mold infected part or tools left on the floor.
