Discover 13 practical ways to use baking soda around the home, from deodorizing carpets and refrigerators to gentle cleaning and freshening routines, plus important safety tips for skin and household use.
That little box of baking soda sitting in your pantry may be one of the most versatile household staples you own.
Also known as sodium bicarbonate, baking soda is inexpensive, mildly abrasive, and useful for neutralizing certain odors. It’s commonly used in cooking, cleaning, laundry, and everyday household maintenance.
But viral posts sometimes go too far, presenting baking soda as a cure for almost every health or beauty problem. The reality is more practical: baking soda can be useful for certain household jobs, but it isn’t a miracle treatment.
Here are 13 sensible ways to use it.
1. Freshen a Refrigerator
Baking soda can help neutralize some unpleasant odors inside a refrigerator.
Place a small open container of fresh baking soda toward the back of the refrigerator and replace it periodically.
Remember that baking soda doesn’t remove the source of an odor. Spoiled food, spills, and dirty shelves still need to be cleaned.
2. Deodorize Carpets
For everyday household odors, sprinkle a light layer of baking soda over a dry carpet.
Allow it to sit for a period of time before thoroughly vacuuming.
Keep pets and children away while the powder is being applied and avoid creating airborne dust.
3. Freshen Shoes
Shoes can develop unpleasant odors from moisture and bacteria.
A small amount of baking soda placed inside dry shoes can help absorb moisture and reduce odors.
Shake or vacuum the powder out before wearing the shoes again.
4. Clean a Kitchen Sink
Baking soda’s mild abrasiveness can make it useful for cleaning some sinks.
Sprinkle a small amount onto a damp surface and gently scrub with a soft sponge.
Rinse thoroughly afterward.
Before using it on a particular material, check the manufacturer’s care instructions because abrasive products can damage delicate finishes.
5. Remove Light Food Odors From Containers
Plastic food containers can sometimes retain strong smells from foods such as onions, garlic, or spices.
A paste made with baking soda and a little water can be useful for gently cleaning some containers.
Rinse thoroughly afterward and allow the container to dry completely.
6. Freshen a Cutting Board
Baking soda can help clean and deodorize some cutting boards.
Sprinkle it over the surface, gently scrub, and rinse well.
However, cleaning with baking soda does not replace proper food-safety practices. Cutting boards should be washed appropriately after contact with raw meat, poultry, or seafood.
7. Help Freshen Laundry
A small amount of baking soda added to a laundry load can help with odors.
However, always check your washing machine and detergent manufacturer’s recommendations before adding household products.
Baking soda should not be mixed indiscriminately with other cleaning chemicals.
8. Clean Some Household Surfaces
Because baking soda is mildly abrasive, it can help remove certain residues from durable surfaces.
Mix it with a little water to create a paste and use a soft cloth or sponge.
Test an inconspicuous area first, especially on painted, polished, coated, or delicate surfaces.
9. Freshen a Trash Can
Even when garbage bags are changed regularly, trash cans can develop lingering smells.
After emptying and cleaning the bin, a small amount of baking soda can help absorb residual odors.
Keeping the container dry is equally important.
10. Deodorize Upholstery
Baking soda can sometimes help freshen fabric-covered furniture.
Apply a light amount to a dry, compatible fabric and vacuum thoroughly afterward.
Always check the manufacturer’s cleaning instructions first. Some upholstery fabrics should only be professionally cleaned or treated with specific products.
11. Freshen a Pet Area
Baking soda can be useful for reducing odors around some household pet areas.
However, avoid letting pets inhale or consume loose baking soda. Keep the powder away from food and water bowls and clean it up thoroughly.
For persistent pet odors, identify and clean the underlying source rather than simply covering it.
12. Gentle Household Scrubbing
For some durable surfaces, baking soda can provide gentle mechanical cleaning without the stronger smell associated with certain commercial cleaners.
A small amount mixed with water can be used as a mild scrub.
Again, avoid assuming that every surface is compatible. Natural stone, delicate finishes, and certain metals may require specialized cleaning products.
13. A Simple Hand-Freshening Scrub
Baking soda is sometimes used in DIY beauty routines as a gentle exfoliant.
However, facial and body skin can be sensitive to alkaline substances, and baking soda can disrupt the skin’s natural barrier.
If you choose to use it on skin, avoid aggressive scrubbing, broken skin, and sensitive areas. Stop immediately if burning, redness, itching, or irritation occurs.
For regular skincare, products specifically formulated for skin are generally a safer choice.
What About Baking Soda for Heartburn?
This is where extra caution is important.
Baking soda contains sodium bicarbonate and can temporarily neutralize stomach acid. However, using it as a homemade antacid is not appropriate for everyone, particularly in large amounts or repeatedly.
The added sodium can be problematic for some people, and excessive ingestion can cause serious electrolyte and acid-base disturbances.
People with high blood pressure, heart failure, kidney disease, or sodium-restricted diets should be especially cautious.
For recurring heartburn, it is better to identify the underlying cause and discuss appropriate treatment with a healthcare professional.
Don’t Mix Baking Soda With Random Cleaning Chemicals
One of the most important household-safety rules is to avoid experimenting with combinations of cleaning products.
In particular, never mix bleach with acids or ammonia-containing products, because dangerous gases can be produced.
Baking soda itself is relatively mild, but that doesn’t make every combination safe.
When in doubt, use one product at a time and follow the manufacturer’s instructions.
Baking Soda Isn’t a Cure-All
Online claims sometimes suggest that baking soda can:
- Cure serious diseases
- Detoxify the body
- Treat cancer
- Permanently whiten teeth
- Eliminate infections
- Reverse chronic health conditions
These claims should not be taken as medical advice.
Baking soda has useful chemical properties, but those properties don’t make it a treatment for serious illnesses.
The Bottom Line
The humble white box in your pantry really can be useful—but mostly because it’s a versatile household ingredient, not because it has magical healing powers.
From freshening refrigerators and shoes to helping clean certain household surfaces, baking soda has plenty of practical uses.
Use it appropriately, test delicate surfaces first, avoid inhaling or ingesting loose powder, and don’t use it as a substitute for medical treatment.
Sometimes the best household hacks are the simplest ones—and the safest ones are the ones that don’t promise miracles.
