Baking Soda and the Truth About Disinfection

What Baking Soda Can Really Do

Baking soda sits on almost every kitchen shelf—packaged as a gentle multitasker. At home, many folks swear by it for freshening up the fridge, scrubbing the sink, or even calming heartburn. The real question comes up if you end up with a sticky counter after dicing raw chicken: Does baking soda make that counter safe?

Freshening vs. Disinfecting

I’ve always loved using baking soda to lift grease or those stubborn coffee ring stains. It works wonders as a mild abrasive for scrubbing out pots or deodorizing trash cans. The catch? Removing visible grime and neutralizing smells isn’t the same as actually killing germs.

Baking soda, known by its chemical name sodium bicarbonate, helps lift dirt and absorbs odors because it breaks down grease and alters pH on surfaces. This makes your sink shine or your cutting board cleaner on the surface, but the EPA and CDC don’t list it as an approved disinfectant. Viruses and bacteria have tough structures that baking soda, used alone with water, doesn’t break down or destroy.

Looking at the Science

Research tells a simple story. Disinfection calls for agents that attack and kill bacteria or viruses. Bleach, hydrogen peroxide, and alcohol land on that list; baking soda doesn’t. Scientists have tested baking soda against some bacteria strains, but its impact falls short of disinfection standards set by health organizations. No health authority recommends it for tasks like cleaning up raw meat residue where pathogens like Salmonella or E. coli could linger.

Risks of Assuming It’s Enough

I’ve seen people sprinkle baking soda in gym shoes, on sponges, or even in bathrooms, thinking it’ll knock out germs. That confidence can backfire. If raw egg spills onto a chopping board, a sprinkle of baking soda might mask some odors or lift the mess, but bacteria can stay behind. Spoiled food or kitchen spills involving meat need a proper disinfectant. Thinking baking soda alone leaves things “safe” could lead to foodborne illness or unexpected bugs in the kitchen.

Better Ways to Kill Germs

Stick to tried-and-true products that target bacteria and viruses—plain household bleach diluted in water, hydrogen peroxide, or EPA-certified sprays work. I keep a spray bottle of water and bleach to wipe down sinks, especially after prepping chicken or fish. It only takes a few minutes to kill off troublemakers that cause illness.

For daily cleaning, baking soda pulls its weight. On grimy sinks and stovetops, it excels as a gentle scrub. But before preparing a meal or after cleaning up animal messes, I switch to sanitizing sprays or hot, soapy water for plates and counters. The label on a cleaning product matters, and so does the science backing it up.

The Bottom Line

Experience and the research both point the same direction—baking soda shines for cleaning and deodorizing, not killing germs. Count on it for elbow grease, not sterility. If you want peace of mind about germs in the kitchen or bathroom, reach for proven sanitizer—not just the bright orange baking soda box next to your flour.
