If you’ve been following me for any length of time, you know I love finding simple, inexpensive ways to support health and make life easier.
While I enjoy learning about the latest wellness trends, peptides, supplements, and skincare innovations, some of my favorite tools are the ones that have been around for generations.
One of those tools is baking soda.
Most people know baking soda as the white powder sitting in the back of the pantry waiting for the next batch of cookies. But this humble ingredient has been used for decades for everything from heartburn relief and oral health to cleaning, deodorizing, and even athletic performance.
I always have a box (or three) in my house.
I use it to wash produce, clean my sink, freshen drains, make DIY laundry detergent, and occasionally brush my teeth. I even add it to certain detox baths along with Epsom salts and bentonite clay.
So let’s dive into what baking soda actually is, how it works, and why it may be one of the most versatile products you can keep around your home.
What Is Baking Soda?
Baking soda is the common name for sodium bicarbonate.
It is a naturally occurring alkaline compound with a pH of about 8.3, meaning it helps neutralize acids.
That simple property is responsible for many of its uses.
When it comes into contact with an acid, a chemical reaction occurs that produces carbon dioxide gas. That’s why baked goods rise.
But outside the kitchen, its ability to neutralize acids, absorb odors, and gently cleanse surfaces makes it incredibly useful.

Do You Need Aluminum-Free Baking Soda?
One question I get asked occasionally is whether baking soda contains aluminum. The answer is a little confusing because people often mix up baking soda and baking powder.
Pure baking soda is simply sodium bicarbonate and does not contain aluminum. However, some baking powders contain aluminum-based ingredients that help baked goods rise.
That said, I personally choose aluminum-free products whenever possible, especially for the items I use regularly around my home and on my body.
For years, I’ve purchased aluminum-free baking soda because I use it for so much more than baking. It’s in my DIY laundry detergent, produce wash, occasional toothpaste treatment, bath soaks, and household cleaning routines.
While the scientific evidence suggests that pure baking soda itself does not contain aluminum, choosing an aluminum-free brand gives me peace of mind and aligns with my overall approach to reducing unnecessary chemical exposures whenever practical. If you’re buying a personal care product, choose a reputable brand because quality, purity standards, and sourcing can vary among manufacturers.
The good news? Aluminum-free baking soda is inexpensive, easy to find, and works exactly the same way for all of the uses discussed in this article.
Heartburn and Indigestion Relief
One of the oldest medicinal uses of baking soda is relieving occasional heartburn.
Heartburn occurs when stomach acid moves upward into the esophagus, causing that familiar burning sensation in the chest. Because baking soda is alkaline, it can temporarily neutralize stomach acid. Many people mix about ½ teaspoon in a glass of water and drink it for occasional relief.
The science is straightforward: Acid + Baking Soda = Neutralization. As the acid becomes less acidic, symptoms often improve quickly. I’ve personally used this on occasion when I’ve eaten something that didn’t quite agree with me.
That said, baking soda is not a long-term solution for chronic reflux or GERD. Frequent heartburn warrants a conversation with your healthcare provider, as there may be an underlying issue that needs attention.
Athletic Performance and Exercise Recovery
This is one use that surprises many people. Research has shown that sodium bicarbonate can improve performance during high-intensity exercise.
When we exercise intensely, our muscles produce hydrogen ions and lactic acid. These compounds contribute to the burning sensation and fatigue that occur during challenging workouts.
Baking soda acts as a buffer. It helps neutralize excess acidity in the body, potentially allowing athletes to perform at higher intensities for longer periods before fatigue sets in.
This is why some competitive athletes use sodium bicarbonate before events involving sprinting, rowing, swimming, or high-intensity interval training.
The downside? Too much can cause significant digestive upset, bloating, nausea, and diarrhea.
For that reason, I don’t personally use this for workouts (I’m not a competitive athlete, not even close), but it’s an interesting example of how something so simple can have measurable physiological effects.
Oral Health and Teeth Whitening
One of my favorite uses for baking soda is oral care.
A few times a month, I’ll dip a damp toothbrush into baking soda and gently brush my teeth. Why does it work?
It is mildly abrasive, meaning it helps remove surface stains without being overly harsh. It also creates an alkaline environment in the mouth.
Many cavity-causing bacteria thrive in acidic conditions. By helping neutralize acids, baking soda may support a healthier oral environment. In fact, many commercial toothpastes contain baking soda as an active ingredient.
Some benefits include:
- Freshening breath
- Removing surface stains
- Helping reduce plaque buildup
- Neutralizing acids in the mouth
Just don’t brush aggressively. More isn’t better when it comes to your enamel.

A Natural Deodorant
Body odor isn’t caused by sweat itself. It’s caused when bacteria break down sweat on the skin. Since baking soda helps neutralize odors and alter pH levels, many people use it as a natural deodorant.
A small amount applied under the arms can help absorb moisture and reduce odor-causing bacteria. Some people love it. Others find it irritating.
If you have sensitive skin, proceed cautiously or mix it with a little coconut oil before applying.
Soothes Itchy Skin and Irritation
Baking soda baths have been used for generations to help calm irritated skin.
Because it can help neutralize irritants and soothe itching, it is often used for:
- Bug bites
- Mild sunburn
- Poison ivy
- General skin irritation
Personally, I occasionally add baking soda to baths along with Epsom salts and bentonite clay. It’s one of my favorite ways to detox and unwind after a long week. Many people, including myself, report softer skin and reduced itching after soaking for 15-20 minutes.
Acne and Gentle Exfoliation
While I wouldn’t recommend using baking soda as a daily facial cleanser, some people use it occasionally as a gentle exfoliant.
Its fine particles can help remove dead skin cells and leave skin feeling smoother. Some also find that its ability to absorb excess oil helps reduce occasional breakouts.
However, this is one area where moderation is important. Your skin naturally maintains a slightly acidic protective barrier. Overusing baking soda can disrupt that barrier and potentially lead to dryness, irritation, or increased sensitivity. If you choose to try it, think of it as occasional treatment rather than a daily skincare routine.
The Produce Wash I Use Every Week
One of the most practical uses in my home is washing fruits and vegetables.
Even organic produce can contain dirt, bacteria, and residue from handling and transportation. A simple baking soda soak may help remove surface contaminants.
I typically fill a large bowl with water, add a small amount of baking soda, soak produce for several minutes, then rinse thoroughly.
It’s inexpensive, easy, and gives me peace of mind. No fancy produce washes required.
Cleaning Your Sink Naturally
My kitchen sink gets a regular baking soda treatment. Because it is mildly abrasive, baking soda can remove grime, stains, and buildup without scratching most surfaces.
I simply sprinkle some into the sink, scrub with a sponge, and rinse. The result is a cleaner, fresher-smelling sink without relying on harsh chemical cleaners.
Deodorizing Drains and Tackling Minor Clogs
Another one of my favorite household tricks is using baking soda and vinegar in the drain. If you’ve never tried this, it’s oddly satisfying.
Pour it down the drain. Follow with vinegar. The fizzing reaction helps loosen debris and freshen odors. After allowing it to sit for a while, flush with hot water.
While it won’t solve a serious plumbing issue, it can be useful for maintaining drains and reducing odors.
Freshening Refrigerators, Shoes, and Carpets
Baking soda works because it absorbs and neutralizes odors rather than simply covering them up.
This makes it useful for:
- Refrigerators
- Gym bags
- Shoes
- Pet areas
- Carpets
- Trash cans
A small open container in the refrigerator can help absorb unpleasant smells for weeks.
DIY Laundry Detergent Booster
I’ve also used baking soda in homemade laundry detergent. Because it helps soften water and neutralize odors, it can boost cleaning effectiveness.
Many people add a half cup to a load of laundry to help remove odors from workout clothes, towels, and bedding.
It can also help naturally brighten whites.
Can Baking Soda Help During Colds or Flu?
You may have heard stories about people taking baking soda during a cold or flu.
This idea dates back many decades.
The theory is that creating a more alkaline environment may support the body’s natural defenses. (Lemon juice in water also helps alkalize the body, and it tastes better.)
Historically, some protocols recommended taking small amounts (1/2 tsp) of baking soda dissolved in water several times daily at the first sign of illness.
However, modern scientific evidence supporting the use of baking soda to treat viral infections is limited.
While some people still swear by it, it should not replace appropriate medical care, hydration, rest, or professional treatment.

Other Surprisingly Useful Uses
Think of it as a traditional remedy rather than a proven cure.
Beyond everything already mentioned, baking soda can also be used to:
- Deodorize cutting boards
- Freshen mattresses
- Clean coffee makers
- Remove odors from food containers.
- Neutralize garbage disposal smells.
- Clean stainless steel
- Remove crayon marks from walls.
- Freshen pet bedding
Not bad for something that costs about a dollar.
Precautions and Potential Risks
As much as I love baking soda, more is not better. Because it contains sodium, excessive intake can create problems.
Potential risks include:
- Elevated sodium levels
- High blood pressure concerns
- Fluid retention
- Digestive upset
- Electrolyte imbalances
- Metabolic alkalosis occurs if overused.
People with kidney disease, heart conditions, high blood pressure, or those on sodium-restricted diets should be especially cautious.
It should also be kept away from young children unless specifically recommended by a healthcare provider.
And while it’s useful for occasional heartburn, frequent symptoms deserve medical evaluation.
Kelly’s Final Thoughts
In a world where every new wellness product seems to cost $50 or more, baking soda remains one of the most useful and affordable products you can buy.
I use it regularly around my house for cleaning, washing produce, deodorizing drains, laundry, oral care, and the occasional detox bath.
Is it a miracle cure? No. But it is a versatile, science-backed household staple that has stood the test of time. Sometimes the simplest remedies really are the best.
For less than the price of a fancy coffee, baking soda earns its place in my pantry, cleaning cabinet, and wellness toolbox.
