Baking soda: Cleaning vs killing bacteria

But let’s first try to get a clear idea of ​​what we’re talking about here!

You can clean very well with baking soda. But cleaning is different from disinfecting, sterilizing, and killing bacteria. For example, if I wash my counter with green soap, I will remove visible dirt. 

But all kinds of bacteria will remain. My counter is not ‘sterile’ after that. In other words, you wouldn’t be able to perform surgery on it. The chance of infection is too high,

But that doesn’t matter!

Because in everyday life it is not necessary to kill away all the bacteria’s as some of them are very good for health.

The RIVM website they explain the differences:


Cleaning, also known as cleaning, is the removal of visible dirt and transparent organic material to prevent microorganisms from maintaining, multiplying and spreading. For example, wipe your countertop thoroughly with a microfibre cloth.


Sterilization is a process that kills or inactivates all microorganisms on or in an object. Such that the chance of the presence of living organisms per sterilized unit is less than one in a million. Professionals must do this, according to RIVM.


Disinfection is the thermal or chemical killing or inactivation of microorganisms whereby the number of microorganisms is reduced to an acceptable level.

  • I think Karin’s question is about disinfection.

According to various experts, baking soda indeed has bactericidal properties, but it does not kill all bacteria. For example, Healthcare says that baking soda does not help to prevent infection with a bite wound. They tell you might as well rinse with plain water.

“Although baking soda is often used as a household cleaner, it is ineffective against most bacteria, including salmonella, E. coli. And staphylococcus. If you suspect there has been a contamination of any of these bacteria, ditch the baking soda in favor of a product registered as a disinfectant by the EPA.”

They also write on the Water Council & Health Counsel site that pure baking soda is ‘ineffective’ as a disinfectant.

At the same time, an American study springer found that baking soda helped with fungal infections of the skin and nails. There is also some evidence that baking soda can help improve inflamed gums.

What do the experts say?

We research and interview several experts for an answer to the question: “Does baking soda kill bacteria?” Below the answers;

The chemistry department of the University of Groningen about baking soda

“If you want to work with bacteria, I wouldn’t use sodium bicarbonate. What I have found online is that it does kill some fungi and bacteria but not all. If you want to disinfect your countertop at home, I would use (> 70%) alcohol for this. To keep your actions clean, it is wise to work near a burning flame (within 30cm), but you may not have that at your disposal. “
