What are Molds?


Mold is a fungus.

They live in moist places like soil, plants, and decaying matter.

Although they are a natural part of the environment that breaks down organic matter like dead leaves and other debris, mold growth should be avoided indoors and should be get rid of at once.

Mold spread by producing reproductive cells called spores that pass easily through the air.

These mold spores are so small they can’t be seen by the obvious eyes but are naturally present indoors and in outdoor air.

Mold spores are everywhere.

It can enter the house through the air on open windows, and doorways. Mold spores can set foot on objects and people including clothing, shoes, and pets.

The difference in Mold and Mildew

So as not to be confused, mold and mildew are typically the same. Mildew refers to certain kinds of fungus or to mold growth that has continuous growth habits.

Mildew is also the stain that was left behind by a mold outbreak.

Mold and mildew prosper in places with humid conditions and poor ventilation. The most common cause of mold and mildew on walls are water leaks and condensation.

Types of mold

There are many types of mold and all of them need water or moisture to grow and settle.

Usually, it thrives on buildings or homes that have an undiscovered or unaddressed moisture problem like in old pipes, wood, roofs, and places where moisture is always present.

Mold growth can be seen as spots that may appear black, green, or white in color and smell musty.

You don’t need mold testing to know the type just seeing unsightly dirt or unsuspected splotches is enough to go ahead and get rid of the mold.

Black Mold

There is no single type of mold that is black mold. Most molds are black.

Black mold can be referred to as the type that is scientifically called Stachybotrys Chartarum.

It can be found in houses that have excessive moisture that damages wallboards and other surfaces.

There is no scientific evidence that shows that exposure to this type of mold is dangerous. However, every type of mold has the ability to produce mycotoxin.

Mycotoxins are toxic compound that is naturally produced by certain types of mold.

Always practice caution when removing black mold in abundance.

White Mold

This type of mold is a powdery fungus composed of different fungus species that can appear white, grey, green, blue, or orange depending on the surface that it contaminates.

Like all molds, it thrives in places that are high in moisture like showers, bathrooms, crawl spaces, and leaky walls.

It can quickly spread when cellulose made of starch and sugar are present which is found mostly in wood furniture, ceilings, wood products, beams, and decks.

You can identify if it is white mold by a water test. Fill a spray bottle with water then spritz some on the affected area where the suspected mold is located.

If the pieces go away then it may be salt but if the substance is still on the area then you are dealing most likely with mold.

Controlling Moisture

One way to manage mold removal is by controlling moisture around your house. There is no way to eliminate all mold or mold spores. As long as there is moisture, mold is thriving.

However, the formula to manage mold is by controlling moisture indoors.

1. Fix any leaks in your home’s roof, plumbing and walls so there is no moisture for mold growth.

Moisture is a haven of mold so make sure that no leaks are going on to your roofs, windows, and pipes. When there are already signs of mold on these structures fixing it immediately is the most sensible way to eliminate moisture and mold removal.

2. Keep your home’s level of humidity no higher than 50% all the time.

Humidity changes throughout the day so check on the levels more than once.

3. Invest in a good air conditioner or humidifier.

It’s a good investment to keep the level of moisture under control for your health as mold can also be detrimental especially if you have pre-existing health problems.

4. Be sure that air flows freely within your home.

Exhaust fans that are vent outside your home in the kitchen, bathroom, laundry rooms, and clothes dryer are useful to keep the moisture low.

5. Out with the carpets.

Keep carpets out in places like bathrooms or basements where moisture levels are high.

6. Clean bathrooms with mold-killing products to prevent allergic reactions.

Mold-killing products are a sure way to kill mold. You can use it every other day or every after shower to ensure that there will be no mold growth build-up. Check out The Crown Choice Lemon Zest Multicleaner that can eliminate mold efficiently, is environmentally friendly, and is doesn’t emit fumes.

7. Dry out and clean up the house after a flood within 24-48 hours.

Floods and natural disasters are inevitable as it is a force of nature. Dry surfaces with heated air within 24-48 hours after a flood or typhoon to prevent and eliminate mold spores contaminating your items.

Here’s some information from CDC to help patients with asthma and other respiratory conditions from a mold after a hurricane or tropical storm.

How to Clean Mold Off Walls


Most people see their mold problem when it is already evident on their walls and sometimes it is on the advanced stage of growing.

Mold from walls is the result of constant moisture on your roof or exterior walls that are penetrated with water.

Here are some tips on how to remove mold on walls.

Basement/Concrete walls

The basement is a room that’s below ground level. You might have the laundry room there with the washing machine and dryer.

Needless to say, it is also a place where moisture settles and is therefore prone to mold.

Step 1: Clean the area

You can easily detect mold if you see small black, white, green, and blue spots on the walls. It also manifests in any organic material that is next to the mold-affected areas.

Remove all affected items from the wall and throw away that are heavily infected. Some furniture can still be saved by cleaning it thoroughly but in several cases, it will be better to dispose of them entirely as not to cause additional damage.

Moving these things away from the wall will give you the legroom to remove the mold.

Step 2: Scrub out the mold

Once the area has been cleaned up, your next step is to kill the mold. There are products commercially that you can use to completely kill mold. However, in some instances, the use of bleach and water mixture coupled with vigorous scrubbing will be enough to remove mold and kill it.

Just mix one part bleach and three-part water in a bucket or spray bottle if there are only small mold spots. Let the mixture sit for around 5-10 minutes on the affected area to soak in.

Use a good brush or a heavy-duty sponge to scrub out the mold until it disappears.

Step 3: Post cleaning

After you’ve scrubbed the affected area, you may wipe it with a clean cloth making sure to check the surfaces if there is any mold you may have missed.

Return the furniture and other items into the basement just make sure that they are also mold-free otherwise you’ll be back to where you started in a few weeks.

Remove mold from Painted walls

If you notice even a slight mold on your painted interior walls, mold spores might be just on the surface.

Manage to get rid of mold quickly before this harmful fungus can spread on larger areas that can damage the structural integrity of your home.

The following steps can help you clean and rid of mold from walls effectively.

Step 1: Prepare the area.

Remove any decorative items, fabric materials, pieces of furniture, and electrical equipment from the affected area. Cover the floor, windows, and vents with plastic sheets then make sure that they are secured with tape to be safe. Keep an old towel nearby in case of any spills.

Step 2: Clean the wall.

Remove any dirt or debris from the wall by using a sponge dampened with warm water and a mild dishwashing liquid soap.

Step 3: Clean with natural mold remover.

If the mold spot only covers a small area, you may mix white vinegar and warm water on the spray bottle and squirt generously on the affected area. Then have a good brush to scrub it away

Step 4: Apply a stronger mold remover product.

Try to apply a stronger mold remover product if the natural mold remover doesn’t yield the desired results or if the mold growth is substantially large in size. Use commercial high-performance cleaning solutions that are tough on mold removal but are safe for everyday use.

Or you can mix one part bleach and one three parts water on a spray bottle then spray it on the painted walls. Let it sit for about 5-10 minutes then scrub aggressively until the mold spots disappear. Wipe with a clean cloth or dry it quickly with an electric fan.

Remove mold on Drywalls

If you find your interior wall has been covered with blue and black splotches and is bowed or crumbling, cleaning it to remove mold from drywall will not be sufficient as the mold already find its way to the structure of drywall.

The unpainted drywall is porous therefore is more prone to mold.

When mold from drywall starts to penetrate and begin to grow. This is beyond repair and you’ll most likely replace the affected part completely to get rid of mold.

However, you can still remove mold from walls with a cleaner and a little bit of scrubbing if it is still structurally in good condition and mold hasn’t crept in yet but it is still covered outside with mold.

Here’s the process of removing mold that has grown on your drywall.

Step 1: Cover the surroundings with a clean sheet of plastics
This is to prevent mold spores from breaking loose during the cleaning process otherwise it will get into some household items and floorings.Step 2: Mark the affected area.
Mark the affected area slightly larger than the visible mold spots because unseen mold spores are most likely to be in the adjacent area.Step 3: Cut the affected area with a utility knife.
Make sure that you cut out an area that makes up at least two of the cover beams behind the drywall.

Step 4: Remove the affected patch.
Carefully remove the affected patch of drywall and set it down on the plastic sheet mold side up.
Step 5: Paint the cavity wall.
It is a good idea to paint the wall cavity with good mold-resistant paint to protect it from mold growth in the future.

Step 6: Clean the room.
Clean the entire room with HEPA vacuum to make sure to kill the mold and no mold spores are on the loose.
