What Is Mold?

Mold is a type of fungus; it's a common household problem that can pose health risks if left untreated. Mold thrives in warm and humid environments such as bathrooms, kitchens, or basements and reproduces through tiny mold spores that float through the air until they find a suitable surface to grow on.

Once established on surfaces like walls or floors, it will continue to spread until removed. There are many different types of molds, ranging from toxic black molds to benign white molds but all have one thing in common — they need moisture to survive.

Health Risks of Getting Exposed to Mold

Exposure to indoor dampness and fungi has been linked to upper respiratory tract symptoms like coughing or wheezing in otherwise healthy individuals. In people with asthma or other chronic lung diseases, exposure can lead to more serious illnesses like hypersensitivity pneumonitis or allergic bronchopulmonary mycosis.

What Is Baking Soda?

Before we dive into the details of how baking soda works against mold, let's first define what baking soda is. Baking soda, also known as sodium bicarbonate, is a white crystalline powder that is commonly used as a leavening agent in baked goods. Its mild alkaline pH level and non-toxic properties make it non-toxic to humans and pets and an environment-friendly solution for general cleaning around the house.

Baking soda is one natural cleaning agent that has gained popularity in recent years for its effectiveness against mold. Baking soda works by altering the pH level of substances around it which makes it effective at neutralizing odors. It also acts as an abrasive agent when mixed with water which makes it useful for scrubbing away dirt and grime.

When applied directly onto surfaces affected by mold growth, it can be effective at removing both stains and odors associated with fungal growth due to its ability to absorb moisture from its surroundings.

In addition, studies have shown that sodium bicarbonate (baking soda) kills certain strains of fungi including some species of Aspergillus niger which causes black mold on food products like bread or fruits when grown under laboratory conditions.

Items You'll Need:

  • Baking soda
  • Warm water
  • Gloves and eye protection
  • Spray bottle
  • Scrubbing brush or scouring pad
  • Washcloth
  • Drying towel

Steps for Using Baking Soda to Kill Mold

Let's explore the science behind cleaning mold with baking soda and provide step-by-step instructions for using it effectively. Here are the steps you should take when using baking soda effectively against mold:

  1. When using baking soda to kill mold, wear protective gloves and eye protection before starting the cleaning process to avoid skin irritation or eye damage caused by the mold or cleaning solution.
  2. Mix baking soda with water to make a baking soda solution. The suggested ratio is one-quarter tablespoon of baking soda per cup of water. Baking soda is an effective and natural cleaning agent that can help kill mold and neutralize its odor.
  3. Once the solution is mixed, pour it into a spray bottle for easy application. Using a spray bottle ensures that the solution is evenly distributed over the affected area.
  4. Spray the solution onto the affected area and use a scrubbing brush or scouring pad to remove visible signs of mold. Scrubbing helps to loosen and remove mold from the surface.
  5. After scrubbing, rinse the area with clean water to remove any leftover residue. It's important to rinse thoroughly to prevent any baking soda from remaining on the surface, as it can leave a powdery residue. Once rinsed, use a drying towel to wipe the surface and allow it to air dry completely for mold prevention.

While you can simply follow the steps above to get rid of moderate amounts of mold, in cases where mold growth is extensive or persistent, it is recommended to seek the help of a professional mold removal company, like Euro-Maids, to ensure that the mold is safely and effectively removed without risking any health hazards or further damage to your property.

Other Natural Methods for Killing Mold

Mold can grow on both porous and non-porous surfaces, and different species of mold require different methods of cleaning. When deciding on the best solution for cleaning mold, it is important to take into consideration the type of mold species and the surface that it covers.

While baking soda is an effective natural cleaner against most types of household molds, there are some cases where other mold killers may be required, especially if the affected areas are large or difficult-to-reach spaces where mold may be growing behind walls, etc.

Harsh chemicals should be avoided when cleaning mold, as they can release toxic fumes into the air and cause health problems.

Instead, opt for natural cleaning agents like vinegar, tea tree oil, and hydrogen peroxide. These environmentally-friendly solutions can effectively remove mold and prevent mold growth in the future.

  • White distilled vinegar contains acetic acid and can also be used to kill mold. Pour vinegar directly onto the moldy area or create a water solution in a spray bottle.
  • Tea tree oil is a natural antifungal agent, and can also be used as a mold killer by mixing a few drops with warm water and spraying the affected area.
  • Hydrogen peroxide is a mildly acidic solution that can be poured directly onto the moldy surface and left to sit for one hour before being rinsed off with warm or hot water.


When dealing with a mold problem, it is important to take action as soon as possible to prevent it from spreading. By taking preventive measures to reduce the risk of mold appearing around your house and cleaning mold with vinegar and baking soda, you can keep your home free from mold and enjoy a safe and healthy living environment.

However, in cases of extensive or persistent mold growth, it is recommended to seek the help of a professional mold remediation company to ensure the mold is properly removed and the affected area is thoroughly cleaned.
