Mold and cleaning

Mold can be a troublesome issue, and it is important to know how to deal with it. In this post, we provide insights into mold and cleaning and share useful tips for cleaning mold from different surfaces. From identification to remedies and preventive measures, here is what you need to know to tackle mold in your home! 

 

 

 

First, what is mold? Mold is a collective term for all microscopic fungi Mold grows on a nutrient-containing substrate, such as firewood, but mold can also grow on other organic materials; however, it needs something to take hold in and begin growing. Therefore, maintaining a decent level of basic cleanliness and not giving mold too much to start growing in is often a good idea.

Mold can, for example, grow on inorganic materials such as concrete if the surface is damp and contaminated with dust, soil, or other dirt.

Inorganic and clean surfaces resist mold growth well, such as well-maintained tiles. Mold thrives in a damp environment and often affects buildings where ventilation or moisture protection does not work.

 

This sofa had been left in a damp environment and, in addition, the area around all the buttons was full of biological material (cheese puffs, bread crumbs, etc.) that had created a perfect environment for mold to attack the furniture. We brought it in and cleaned it with soap spray and a cloth. Once the biological material had been cleaned away, the sofa was allowed to dry thoroughly. The same cleaning was then carried out once more, and the furniture is now dry again and free of mold. The infestation was therefore only superficial and localized and could be cleaned away. (Use respiratory protection even for superficial infestations like this one.)

Not all mold is dangerous, but it is very difficult to know whether it is dangerous or not unless you are very knowledgeable about mold, so seek professional help if you have a mold infestation at home. Mold can be harmful to both your home and your health, so you should be vigilant. You can suffer from anything from headaches to poisoning caused by mycotoxins. If you suspect a mold infestation in your home, it should be inspected, because it is by no means certain that it will be visible or detectable by smell, even though it often is both visible and detectable by smell.

Mold can of course also be beneficial, For example, brush mold is used to produce antibiotics and penicillin, but the chance that you would have a basement full of penicillin is nevertheless small, so look into it!

But don't panic about mold; mold is all around us after all and is a natural part of our environment, Mold spores are always present in the air over land. In winter, there may be as few as 10 spores per cubic meter, but in summer it is common to have more than 10,000 spores per cubic meter in outdoor air.

 

Here we have obvious water damage. This problem cannot be solved by cleaning. Professional help is needed to repair the moisture damage and carry out remediation.

 

For example, Alternaria, Cladosporium, and Fusarium are found over fields, while Aspergillus and Penicillium are more common indoors and sometimes in woodland areas. We do not notice or suffer any harm from these. Problems can arise only when the spores begin to grow and form mold. For that to happen, moisture, nutrients, and the right temperature are needed.

Damage-causing fungi often first affect homes at 5–10 °C. On a nutrient-rich substrate, however, mold can grow close to 0 °C, such as mold on fruit in a cold refrigerator.

Can you fix it yourself?
-Yes, if the mold is superficial, that is fine. If it is a larger problem or a more extensive infestation, professional help is needed.

For example, I found a soccer sock at the bottom of a laundry basket. It had been put in the basket wet, with a wet towel on top, and had been left there while we were away for a couple of days—and yes, it had become moldy. This is not a mold infestation that needs to be handled by a professional; it is localized and the cause is obvious. A wet sock was left at the bottom of a plastic laundry basket. All the conditions for mold growth were present, but it was easy to fix. I scrubbed out the laundry basket with soap, and washed the towel and socks in the washing machine. 

 

If you have localized mold to clean up, wear a face mask as a precaution. Gloves are also recommended, and if there is a lot of mold, safety goggles are a good idea too. 

Locate the source: Try to find out why there is mold. Is it just a wet sock, or is there an underlying cause, such as water damage, damaged surface finishes, or poor ventilation?

Clean with soap and water, or alternatively baking soda. Fungi and mold thrive in an acidic environment but not in an alkaline one. Dry thoroughly and make sure no water remains; airing out and drying are key to keeping mold away.

 

Mold and silicone sealant: Silicone sealants often develop black mold spots over time, and unfortunately, they are often located beneath the sealant, so it makes no difference how much you try to clean the surface.

The silicone seal needs to be removed and redone. Mold-resistant silicone is now available at building supply stores. Feel free to use this type of silicone AND carefully investigate whether the underlying problem is water damage, in which case it needs to be repaired by a professional.
When you are finished, check regularly to make sure the problem does not return, because then you need to investigate the source more thoroughly. 

 

Mold and tile grout: Has the tile grout become discolored? It is not necessarily mold; it could also be limescale or biological dirt, skin deposits, soap residue, and so on. These are things you can remove with soap and a stiffer brush. And as mentioned above, mold needs something to grow on; cleaning thoroughly reduces the risk of mold spores taking hold.

Fusarium is a fungus that is slightly red or pink in color. It also thrives in and is very common in showers and bathrooms; scrub it off and keep it away with soap and a brush.

 

Vacuum cleaner and mold: If you have vacuumed up mold, the vacuum cleaner must be cleaned thoroughly and all filters replaced; otherwise, you risk spreading the mold spores through the vacuum cleaner.

 

Here, an interior door had been left in a damp storage room. This was also only surface mold and could be scrubbed off easily.

Quick recap

1. Use at least respiratory protection, and preferably gloves and safety glasses as well.
2. Find out the cause / locate the source.
3. Clean and check that the mold does not return.
4. If the problem returns or the source cannot be located, you need to contact a professional and possibly your insurance company as well.

1. What are the most common places where mold can grow in the home according to the post?

The most common places where mold can grow in the home are on organic materials such as wood, but it can also occur on inorganic materials such as concrete if the surface is damp and dirty.

 

2. Why is it important to find and address the source of mold growth?

Finding and addressing the source of mold growth is important because mold thrives in damp environments and needs a nutrient source to grow on. If the source is not addressed, mold growth may return despite cleaning measures! 

 

 

3. What are the benefits of using soap and water to clean mold?

The benefits of using soap and water to clean mold are that fungi and mold thrive in an acidic environment but not in an alkaline one. Soap makes the surface alkaline and therefore less favorable for mold growth.
