How To Remove Green Mold From A Wood Deck
To remove green mold from your , you will need to give your deck a regular brush with a stiff broom. Using a pressure washer on your deck at least once a year is an extremely effective way of banishing any build-up of dirt and algae, too, as well as giving your deck a fresh look by bringing the wood back to its original color.
If you do use a pressure washer to remove green mold or mildew from a wood deck, bear in mind that timber is made of fibers which can open up if exposed to too much pressure, which can cause the deck to become vulnerable to rot, so make sure to keep the washer’s head at least six inches away from the deck boards, and ensure the pressure washer is on a wide spread setting.
Chris Moorhouse, Category Director for Timber with Wickes suggests investing in a wood cleaner, which remove algae and stains with a biodegradable mixture without damaging the deck with other, harsher products. Wood cleaner can be easily brushed into your deck and washed off with water and a stiff brush, keeping your deck clean of algae. This is a good, if slightly more labor-intensive, alternative to using a power washer and needs only to be reapplied every few months.
A further step you can take to avoid the green algae building up on decking is to replace old boards with anti-slip decking, which is less prone to algae buildup.
What I Was Starting With
Mold outdoors, on a fence or decking for example, is fairly normal. It’s not pretty and will damage the wood over time but it’s not that harmful in the grand scheme of things. However, mold indoors should be removed asap as the spores are toxic to humans, especially anyone susceptible to allergies.
Speaking with Edward Jones, Founder of HomeCareHow he noted: ‘Mold can be harmful to your wood. It lives on living organisms and slowly damages your wood surfaces. Mold can be transported through water, air, and surfaces it touches. It causes health problems, especially for people with allergies.’
With that in mind, I grabbed a few of my go-to cleaning tools…
What Kind Of Vinegar Should You Use
First, save the apple cider vinegar for salad dressing. To clean mold, use regular white distilled vinegar, typically sold with 5% acidity. You can also use cleaning vinegar with 6% acidity. Both are effective at killing mold. Generic brands are as effective as name brands. You can find cleaning vinegar online and at many home improvement, discount and grocery stores.

What To Do If Mold Persists
If the mold stains still remain, the wood surface will need to be sanded to remove the spores that have deeply penetrated the wood. If you are not familiar with wood sanding or refinishing, ask questions at a home improvement store about the right sandpaper grit to use for your situation. After sanding and vacuuming away all of the grit, the wood should be refinished or sealed to help prevent future damage.

Mildew can be found on many different surfaces. It is a thin, black, or sometimes white, growth produced by mold. Molds are simple plants belonging to the group known as fungi. Though molds are always present in the air, those that cause mildew need moisture and certain temperatures to grow. They commonly develop in humid summer weather, especially in closed houses.
These molds grow on anything from which they can get enough food. In homes they develop most often on cotton, linen, rayon, silk, wool, leather, wood and paper. Many synthetic fibers resist mildew.
Molds that cause mildew flourish wherever it is damp, warm, poorly lighted and/or where air is not circulated in cellars, crawl spaces of houses without basements and clothing closets. It can also be found on draperies and rugs in basement recreation rooms, on shower curtains and on damp clothes rolled up for ironing. These molds are also likely to grow in a new house because of moisture in the building materials.
As the molds grow, they cause considerable damage. They leave a musty odor they discolor fabrics and sometimes they eat into them until the fabrics rot and fall to pieces. They also discolor leather and paper.

Tip On How To Get Rid Of Mold On Wood Using Bleach
In extreme cases or the case of untreated wood, mold can penetrate the wood and make itself at home. If it penetrates, you will need a stronger cleaner something more than just soap and water to clean outdoor wood furniture.
You can make up as much or as little of this powerful cleaning solution as you would like, as long as you keep the parts the same. In a big bucket mix together all three ingredients. Apply the bleach solution to the wood using a stiff-bristled brush or a scrubbing sponge. After scrubbing the wood, allow it to air-dry.
Use dehumidifiers and fans to help speed up the drying process, but allow the wood to dry for at least three days. Inspect the wood for any signs of mold, and look and smell the wood. If mold is still present, your best mold remediation is to clean with the bleach solution again.
Once you know its is no longer present, seal the wood with a primer or pigmented shellac from your local hardware stores. If mold is still present or you notice mold stains, your only other option is to sand the wood. Using sandpaper to sand down the wood allows you to reach the mold or stains that are deep inside.
You dont want to do a quick sanding instead, slowly sand the wood until either the mold or the mold stains are gone. Once gone, you should stain, paint, or treat the wood to help prevent future problems.

Cleaning Mold Off Hardwood Floor
Trying to clean mold off the wood floor is a bit trickier since you have to be especially careful not to damage it. For example, acidic cleansers like lemon juice can damage the sealing on your hardwood floor.
When it comes to cleaning mold off of wood, there are a few things you need to keep in mind. First of all, you should avoid using harsh chemicals like ammonia or abrasives. These could damage the finish and make it more difficult to clean the mold in the future.
Instead of harsh chemicals, you can use dishwashing soap, or borax, for example.
If youre unsure how to clean white mold off wood without damaging the finish and sealing on your flooring, commercially available effective hardwood floor cleaners are the best way to go.
Whatever you decide to use on your floor, the first step is to vacuum up as much visible debris as possible. This will remove all loose dirt and mold spores so that they dont become airborne later in the cleaning process.
What Causes Mold On Wood These 2 Things
Mold can be found growing on virtually any surface, that is, if it has a food source, enough moisture, and the ideal conditions
Cellulose-based materials like wood provide the perfect source of nutrients to promote mold growth.
How does this happen?
1. Moisture Content of Wood
First, lets look at the moisture content of wood. The Moisture Content of wood is the total amount of water present in the material.
In general, the moisture content of wood depending on the species generally falls between 8% to 19% by weight.
When a contractor uses wood to build your home, the ideal moisture content should be around 14%.
When the moisture content of wood gets to the 20% range and higher, significant mold growth will begin to occur in several days.
No matter where you are or where you live, youre exposed to mold spores.
When mold spores are floating around in the air land on a wet piece of wood, lumber or any material that it can break down and digest, guess what?
The spores will begin to germinate and grow on the surface of that material.
So, a piece of wood, furniture or other cellulose-based material that gets wet and is not dried within 24-48 hours provides the ideal habitat for mold to grow a rapid pace.
To illustrate this, take for example a recent natural disaster, Hurricane Michael, that occurred in Florida.
This storm caused storm surges which flooded many homes along the FL panhandle.
Mold can grow on wood because of:

Is Green Mold Dangerous
Green mold on deck surfaces may be less worrisome than if it was growing in your basement or bathroom, but it is still a health hazard. Mold releases airborne spores that affect those with asthma, allergies, and other respiratory concerns. Decks are often located near homes, and mold spores can easily drift through screens and into homes to affect your family.
Mold can cause headaches, rashes, nervous-system disorders, and some types are linked to blood poisoning and even brain infections. It has also been linked to cognitive concerns like memory loss, depression and mood swings, dizziness, and fatigue. Green mold is toxic, and while it may not kill you, it can seriously affect your health.
Other Mold Prevention Methods
Your first plan of attack is always preventing growth in the first place. To do this, you need to find out what is causing the moisture in your crawl space.
Check your dirt and your pipes. If your pipe is leaking, fix it. If the issues seem to be the dirt, you can place a dehumidifier or moisture absorber in your crawl space.
Here are a few other methods to help you prevent moisture in your crawl space:
- Add a plastic vapor barrier.
- Seal up your vents

If you discover a mold infestation in your home and want to understand the health risks, you need to first find out the species of mold you are dealing with. For this, specialized mold testing is required.
And while you can guess at the species based on environmental factors like food source , the only way to determine the species of mold growing on your walls, floors or ceilings is to have a specimen tested in a microbiological laboratory.
How To Remove Green Mold From A Wooden Deck With Oxygen Bleach
For years, people have used chlorine bleach to clean their decks and for removing mold. While this is a useful measure for killing fungi, it can cause damage to the wood fibers. A safer alternative to chlorine bleach for mold cleaning is oxygen bleach. This homemade deck cleaner utilizes the strength of oxygen bleach, Borax, and soap to remove mold.
Sweep dirt and debris off the deck before you begin this method. Add the water, oxygen bleach, soap, and Borax into the bucket and mix the solution well until everything has dissolved. Apply the bleach solution by dipping the brush into the bucket and sloshing the mixture onto the wood.
Begin at the farthest side of the deck and work your way to the other as you scrub the deck surface. Re-wet the brush as needed. Allow the solution to sit on the decking for about 15 minutes and rinse the entire surface using a garden hose. You may opt to follow this treatment with a deck brightener solution.
