Mold loves to grow in dark, damp places. That’s why you’ll often find it in kitchens, basements, and bathrooms. And while it might seem like a minor annoyance, mold exposure can lead to respiratory issues and skin infections. It’s especially risky for people with existing health problems.
So, what can you do? Many people are turning to natural solutions like baking soda to tackle their mold problems. But does baking soda actually kill mold?
That’s what we’ll explore in this article: can baking soda really get rid of mold, or are you better off reaching for something stronger?
Understanding Mold: What is it and Why is it Harmful?
Mold and mildew are types of fungi that grow in damp and humid environments. Mold is a fungus. Mildew is a type of mold that tends to grow on the surface of things.
Mold needs moisture, warmth, and a food source to grow, so it’s often found in places with poor ventilation.
Mold exposure can lead to a range of health problems, including respiratory issues like coughing, wheezing, and asthma. You might also experience allergic reactions, such as skin rashes and itchy eyes.
Children, the elderly, and people with weakened immune systems are especially vulnerable to mold. In some cases, mold can contribute to conditions like hypersensitivity pneumonitis and allergic bronchopulmonary mycosis.
Baking Soda: Properties and Mechanism of Action
Let’s take a closer look at baking soda, also known as sodium bicarbonate, and how it works to combat mold.
What is Baking Soda?
Baking soda is a mild alkaline substance that’s safe to use in your home. It’s also an environmentally friendly cleaning agent.
How Does Baking Soda Kill Mold?
Baking soda alters the pH level where it’s applied, creating an environment where mold struggles to survive. It also neutralizes the odors that often accompany mold growth.
Baking soda also has slightly abrasive properties, so it can help physically scrub mold off surfaces.
Some studies show that baking soda can kill certain types of fungi, like Aspergillus niger. Keep in mind that its effectiveness can vary depending on the type of mold you’re dealing with.
Step-by-step guide: Using baking soda to kill mold
If you’re going to try using baking soda to tackle a mold problem, here’s a guide that’ll walk you through the process.
Preparing for mold removal
- Gather your supplies: baking soda, water, spray bottle, scrubbing brush, gloves, and eye protection.
- Take safety precautions: Wear gloves and eye protection to avoid getting mold on your skin or in your eyes. Be sure to ventilate the work area well.
The mold removal process
- Mix your baking soda solution: Mix about ¼ of a tablespoon of baking soda for every cup of water you’re using. Stir until the baking soda is fully dissolved.
- Apply the solution: Pour the solution into a spray bottle and thoroughly spray the areas affected by mold.
- Scrub and rinse: Use a scrubbing brush or scouring pad to remove any visible mold. When you’re done scrubbing, rinse the area thoroughly with clean water.
- Dry the surface: Wipe the surface with a clean towel, and then allow the area to air dry completely.
Baking soda vs. other natural mold removal methods
Baking soda isn’t the only natural substance people use to rid their homes of mold. Here’s how it stacks up against some other common methods:
Vinegar
Vinegar is a natural acid that’s effective at killing mold, especially on hard, non-porous surfaces.
Compared to baking soda, vinegar has a stronger smell, and baking soda is generally gentler and less likely to damage surfaces.
Tea tree oil
Tea tree oil is a natural antifungal that can kill mold, but it tends to be more expensive than baking soda or vinegar.
Hydrogen peroxide
Hydrogen peroxide is a bleaching agent that can kill mold. Because it’s a bleaching agent, it’s best to use it on light-colored surfaces, as it can discolor darker materials.
When to call a professional
Baking soda works well on small mold problems. But sometimes, you need to call in the experts.
You probably need professional help if:
- You have mold growing in an area larger than 10 square feet.
- The mold is growing in a hard-to-reach place, like behind walls or under floors.
- The mold keeps coming back, no matter how many times you clean it.
Mold remediation specialists have equipment and expertise that the average homeowner lacks. They can also find and fix the source of the moisture that’s feeding the mold.
If you have a serious mold problem, don’t disturb it. You could release spores into the air. If you try to clean it yourself, wear protective gear, including a respirator.
In Conclusion
For minor mold problems, baking soda can be an effective, safe, non-toxic, and environmentally friendly solution.
However, baking soda won’t prevent mold from coming back if you don’t fix the underlying moisture problem. Regular cleaning and maintenance are essential for keeping mold at bay.
Consider baking soda as part of a broader mold prevention strategy. You can combine it with other natural methods for the best outcome. And if you have a large mold problem, don’t hesitate to seek professional help.
