Here’s A Fact For You:

Molds are everywhere in our environment, both indoor and outdoor. Their role is vital to the ground due to their function – digesting organic matter such as dead leaves.

Molds grow by reproducing microscopic spores, which is too small for our naked eyes to notice. These spores are ever-present in the air and go to a great distance for their new habitat.

In order to grow, mold spores need to find an ideal environment with organic food. The mold spores’ journey will end when they land on damp places caused by roof leaks, condensation, or lack of ventilation. Some common areas that can have molds:

  • Bathroom
  • Basement walls
  • Areas around the window
  • Areas near leaky water

Therefore, moisture-control is extremely important if you want to prevent mold from forming in your home.

Besides dampness, mold needs a food source to nurture itself. Mold’s food is organic substances such as papers, cloth, wood, and plant material.

Therefore, your carpet, a highly absorbent surface with many types of dust, can be an ideal environment to mold if you don’t take care of it properly.

It only takes a water splash and a mold spore landing on the right place to damage your carpet.

When the molds grow from carpet, it is rarely visible on the surface. In fact, they stay under the rug and even the padding. Certain signs you can tell that there are molds from your carpet:

One of the very first signs is mildew in the carpet. Mildew has a white color, whereas mold is black, blue, or green, depending on the type of mold.

Water damage spots can be a potential place for mold to grow as the growing process can be within 24 to 48 hours. Therefore, it is wise that you quickly dispose of the spots.

If you smell a damp, foul, or stale smell, it is a sign of mold. In addition, discolorations or stains can also be mold.

  • Running nose
  • Asthma attacks on people who have a history of having asthma.

Therefore, having molds on carpet is dangerous to our health as we live and inhale mold spores daily.

Regarding its harm, it is necessary to clean the mold from the carpet as soon as possible to keep a healthy environment.

So, now that you still want to remove the molds at home, here are the steps to clean mold from carpet:

Step 1: Prepare The Products

There are many types of products you can use to remove molds. If the molds are small, you can use baking soda and vinegar. If the molds are larger, it is best to use stronger chemicals such as bleach.

Step 2: Locate The Mold Spots.

As we said above, molds will not be visible on the surface, so you need to look for it underneath, fiber, and padding. A thorough check can help you spot the source of mold and prevent it from growing.

Step 3: Reduce Humidity.

Molds love moisture areas. Thus, we need to repress the growing rates by maximizing ventilation in the room, such as opening windows and putting fans toward the mold areas.

Step 4: Deodorize The Carpet

Use a great amount of baking soda on the mold area and wait for it to absorb all the moisture and foul odor overnight. Then, use a vacuum to remove the baking soda the next day.

The vacuum you use should have a high-efficiency particulate air filter (HEPA) that can trap all the tiny particles, including mold spores.

Step 5: Clean Your Carpet

If there are some mold stains left, you can put pure vinegar in a spray bottle and apply it to the stain. Then scrub it off with a hard brush.

Then, turn on a fan to dry the spots.

At this step, you can use bleach to remove all the spots left. Mix half a cup of bleach in a gallon of water. Then start scrubbing all of the molds off immediately with a brush.

Finish it off by water down all the bleach.

Step 6: Dry Your Carpet
