How to Remove Mold from Wood

Mold can develop on a lot of surfaces in the house. If it can attack your walls, it can also form on wooden furniture that it can destroy in time. To save your pieces of furniture made of natural wood from mold, but also to protect your health, find out how to remove mold from wood!

What is mold and why does it appear on the wood?

type of wood molds

The mold is made up of microscopic mushrooms that multiply by spores and appear in areas with high humidity.

The high humidity will favor both the appearance of the mold and its development.

Indoor mold is different from the mold present in food, and the most common types of indoor mold are Penicillium, Cladosporium, Alternaria and Aspergillus.

Mold can appear both inside a home and outside. Mold spores enter the house by air, but also by heating and ventilation systems.

The surfaces that can be most affected by mold are the kitchen, the bathroom and the balcony, but they can appear in other rooms, if you have problems with the water seepage from outside the house or in the apartment.

Mold appears and develops also on wooden surfaces, it can break down paints or adhesives and that is why you can often find mold on the walls of the house

The main factors that favor the appearance and development of the mold are moisture, heat and lack of adequate insulation.

  • a warm and humid environment : the humidity and the heat from the inside favors the appearance of the mold especially in the cold season, due to the large temperature differences
  • condensation formation : incorrect insulation of the walls will block the transfer of moisture from the inside to the outside and thus the condensate will form, conducive environment for mold development.
  • water infiltration : if the waterproofing is done with poor quality materials, water infiltration can occur in the interior walls of the house.

It is recommended that these works be performed by a professional, to avoid the appearance of mold in time

Types of mold:

White mold – is the most common and forms as a dense white patch that covers the surface.

It is easy to recognize precisely because of the white color and the appearance of white-gray wool.

Aspergillus – is a green mold and is very common in nature – on corn, nuts or straw – but also on the surface of foods such as bread or potatoes

Cladosporium – has a dark green color and appears on textiles or wood surfaces.

Penicillium – can be green, as well as alabaster or blue and usually appears either on fruits and vegetables or on surfaces in the home – walls, wallpaper, carpets, basement corners.

Alternaria – is the one type of fungi that causes brown spots on the leaves and fruits

Stachybotrys – a black-green color, this type of fungi appears more often on wood or gypsum panels

How do we detect mold in places where it is not visible?

Mold is hard to detect because it can also be formed in places out of sight: after large furniture objects, for example.

It is possible to have mold under the parquet, in case you do not see it, but it can affect your health, as well as the one from visible places.

You can realize that there is mold in your house if you feel a specific smell of moisture.

The smell of mold resembles that of moist soil. If you spend a lot of time at home, there is a chance you will not feel it.

However, if you return home after spending some time away, you smell this smell, but do not find the place where it formed, you should investigate its source. If you do not see it behind the furniture items, you should also check the floor.

How to Remove Mold From Garden Wood Furniture

remove mold from wood garden furniture

The green areas with mold that appear on your garden furniture are not attractive and do not turn your terrace into the most attractive place.

Once the green spores have attacked your garden furniture, you need to use mold cleaning solutions and work hard to counter their attack.


They emit microscopic spores into the air that help spread them. They multiply in shady, humid and warm environments.

The cold and dry weather does not annihilate the mold, but slows down their growth process.

It is enough to frequently use water and a hard brush to remove deposits from garden furniture.

If the fungus or mold has attacked your garden wood furniture, you should not leave the furniture outside in the winter, in the hope that the cold weather will remove them.

The cold will only keep the growth of spores under control until the heat and humidity will ensure perfect growing conditions.

So, you should store your furniture in a shed or garage during the winter. This will also prevent unnecessary damage to the furniture.

How to Remove Mold From Garden Furniture

To remove mold from garden furniture you need a hard brush and water. If you fail to clean them you can add vinegar to the treatment.

The mixture must contain vinegar and water. Make sure that you clean all the furniture, not only the attacked parts, because the invisible spores of the algae can spread on all the furniture.

Remember to clean all the corners and cracks with the solution against mold and fungi, otherwise they will reappear soon.


If the mold is still damaging your furniture, and the mixture of water and vinegar has not been shown to be effective, you can take more drastic measures.

There are several types of cleaning solutions that can remove fungi and mold from wood furniture in 1-2 weeks. Another advantage of these solutions is that of surface protection and prevention of new deposits.


Regardless of the material of your garden furniture, the treatment against mold is the same.

However, plastic garden furniture can withstand mold removal methods better than wood, which you need to be careful about if you use a hard brush or pressure washer.

If you choose to remove deposits with a pressure washer, keep a safe distance so that you do not damage the furniture and create irregularities that will facilitate the installation of algae.


Solid wood furniture must be treated with oil, but it must be completely dry before applying the treatment and a suitable oil must be used.

It is recommended to apply an oil treatment two or three times during the season. Teak wood furniture does not require oil treatment, because teak is already a fairly oily wood.

Over time, teak wood furniture takes on a natural white tint that can be removed with teak oil.

If you decide to apply an oil treatment to your furniture, you will need a continuous treatment as in the case of solid wood furniture.


The environment in which the garden furniture is located must be part of the treatment against mold.

If the problem is big, you need to find out where the deposits come from, because you can prevent the problem and stop their development.

Although large trees provide shade, they transmit algae spores to the terrace and garden furniture.

So, you have to think about whether it’s better not to keep your garden furniture away from trees.

Leaks from gutters and downspouts can also lead to increased moisture around garden furniture, providing favorable conditions for mold development.


Mold and fungi on the wooden garden furniture can cause it to rot, due to their moisture.

Therefore, you must be careful about their development if you want to keep your garden furniture beautiful.

Once they have found an incubation place, they will spread a little each day through spores. Therefore, it is important to be careful about their development and to be one step ahead.

The mold should be removed from the garden furniture every spring and autumn when it has the perfect conditions for development in wet weather.

How to prevent mold formation on wood

Prevention is much more effective than treating wood furniture affected by mold.

To prevent any problems, here’s what you should know:

  • The furniture, but also any other wooden objects in the house must be kept permanently dry, in order not to create the environment conducive to mold development.
  • In rooms with high humidity, use a dehumidifier. This will regulate the humidity level and prevent the formation of mold. Frequent ventilation of the rooms is also recommended.
  • In case of a flood or any other incident that causes the wood furniture to damp, allow it to dry as quickly as possible.
  • Don’t forget to take care of the wooden furniture on the terrace or even in the backyard of the house, protecting them from the excessive humidity during the spring and autumn.

An effective way to protect wood surfaces is to apply a waterproofing solution.

Here is a simple and effective method how you can protect your wooden furniture!

How can you prevent the appearance of mold

The best solution against mold is its prevention. The mold is not neglected and you must do everything possible to prevent its occurrence in the home.

There are a few simple methods by which you can keep your mold away from your home:

  • ventilate the rooms: it is advisable to ventilate the rooms at least twice a day to eliminate the moisture accumulated inside the house. The bath is one of the places predisposed to the appearance of mold due to the increased humidity, so after each shower it is advisable to leave the window open or, as the case may be, to start the ventilation for a few minutes.
  • controls humidity: humidity can be controlled using a room hygrometer that indicates the humidity level. The recommended humidity value should be between 30% and 50%, lower in summer and higher in winter. You can keep humidity under control and at the same time to surround your home with plants that absorb moisture: fern, ivy or chamaedorea (dwarf palm).
  • waterproofing: if waterproofing is done correctly, it can prevent mold from appearing inside the home. There are many types of materials that are used for waterproofing and it is recommended that this be done by a specialist so as to remove the problem of water infiltration through the walls.
  • do not dry the laundry inside: evaporation of water inside the house will increase the humidity level. It is advisable to dry the laundry in an open or well-ventilated space
  • use anti-mold paint: a handy solution is anti-mold paint that can be used in rooms with high humidity. If you have the opportunity to decorate your home alone or renovate it, you can use this paint to prevent mold formation.
  • frozen sticks: a modern solution against mold is the use of these frozen sticks.

How are you doing? You must make holes in the wood, at a distance of 11 cm, as close to the foundation of the house.

The depth of the holes must be smaller than the thickness of the walls by 2.5 cm. You must first insert the rods into the freezer, then into the holes in the wall.

After melting the first row of sticks, you must repeat this operation three more times, then you can plaster the wall. The treatment life is 25 years.

Electro-cyber solution is the latest trend in mold prevention. The electro-cyber system is composed of an apparatus that is mounted on the wall of the room, with four screws.

Through long-wave electromagnetic impulses, this device extends the fatigue over a radius of 12 m. The device has a low energy consumption and is effective in preventing mold for 20 years.


Using one the of the above methods you will know how to remove mold from wood.

Wood treatment is one of the best ways to keep mold and other wood pests at bay. This treatment is performed with special solutions that remove all mold spores from wood.

The decision to control mold depends on several factors. In general, surfaces where mold is visible must be cleaned and people come in contact with it.
