7 Survival Uses for Baking Soda You Never Knew
Share
When most people think of baking soda, they picture cookies, cakes, or a box sitting in the back of the refrigerator.
But this inexpensive household staple is one of the most versatile items you can keep in your emergency supplies.
A single box of baking soda can help with hygiene, cleaning, cooking, odor control, and even minor emergencies. It's lightweight, inexpensive, stores well when kept dry, and has dozens of practical uses.
If you're looking for budget-friendly ways to improve your emergency preparedness, baking soda deserves a permanent place in your pantry and emergency kit.
Here are seven survival uses for baking soda that every prepared family should know.
Why Keep Baking Soda in Your Emergency Supplies?
During an emergency, you may lose access to running water, cleaning products, or stores. Multi-purpose items become especially valuable because they help you accomplish more while taking up less space.
Baking soda is:
- Affordable
- Lightweight
- Easy to store
- Long-lasting when kept dry
- Useful for everyday life and emergencies alike
The more jobs one item can perform, the more valuable it becomes in a preparedness plan.
1. Brush Your Teeth When Toothpaste Runs Out
If you're without toothpaste for a few days, baking soda can be used to help clean your teeth.
Simply wet your toothbrush, dip it into a small amount of baking soda, and brush gently.
Because baking soda is mildly abrasive, avoid scrubbing aggressively or using it as your only toothpaste for extended periods. Commercial toothpaste contains fluoride and other ingredients that support long-term dental health.
Still, in a short-term emergency, it can help you maintain basic oral hygiene.
2. Neutralize Odors
In an extended power outage or evacuation, unpleasant odors can build up quickly.
Baking soda naturally helps absorb many odors and can be sprinkled:
- Inside shoes
- In coolers
- In trash containers
- Near portable toilets
- Around pet areas
- Inside food storage bins
A small amount can make shared living spaces much more comfortable during prolonged emergencies.
3. Clean Pots, Pans, and Cooking Equipment
Without your usual cleaning supplies, burnt food and grease can become difficult to remove.
Make a simple paste using baking soda and a small amount of water.
Apply it to cookware, let it sit for several minutes, then scrub gently with a cloth or sponge.
It's an effective way to clean many kitchen surfaces without harsh chemicals. Be sure to test delicate materials first, as mild abrasiveness may not be suitable for every finish.
4. Help Relieve Minor Itching
Mosquito bites, poison ivy, or other minor skin irritations can make an already stressful situation even more uncomfortable.
A paste made from baking soda and water is a traditional home remedy that some people use to soothe minor itching.
Keep in mind that responses vary from person to person, and baking soda is not a substitute for medical treatment. Avoid applying it to broken skin or serious wounds, and seek medical care for severe allergic reactions or persistent symptoms.
5. Improve Your Emergency Cooking
Baking soda isn't just for desserts.
It can also help:
- Tenderize dried beans during cooking
- Reduce acidity in some tomato-based recipes
- Help baked goods rise when paired with an acidic ingredient such as vinegar, lemon juice, or buttermilk
If you're relying on shelf-stable pantry foods during an emergency, these simple tricks can make meals easier to prepare and more enjoyable.
6. Freshen Laundry Between Washes
During extended power outages or situations where water is limited, laundry may need to be worn more than once.
Sprinkling a small amount of baking soda inside shoes or lightly on clothing before airing it out can help reduce lingering odors until proper washing is possible.
It's not a replacement for laundering, but it can help extend clothing use when resources are limited.
7. Put Out Small Grease Fires
One of baking soda's lesser-known uses is helping extinguish small grease fires on the stovetop.
When heated, baking soda releases carbon dioxide, which can help smother a small grease fire.
Important safety reminders:
- Only use it on small cooking grease fires.
- Never throw water on a grease fire.
- If the fire is spreading, evacuate immediately and call emergency services.
- Keep an appropriate fire extinguisher in your kitchen as your primary fire safety tool.
Knowing this simple trick can make a difference during a kitchen emergency—but it should never replace proper fire safety equipment or training.
Bonus Uses Worth Knowing
Baking soda has even more practical applications around the home and campsite, including:
- Deodorizing refrigerators and coolers
- Cleaning reusable water bottles
- Freshening sleeping bags
- Removing coffee and tea stains from mugs
- Cleaning some outdoor gear
- Reducing odors in backpacks and emergency bins
The more familiar you become with everyday household items, the better prepared you'll be when normal conveniences aren't available.
Should You Store Baking Soda for Emergencies?
Absolutely.
A few boxes of baking soda cost very little, require minimal storage space, and can serve dozens of purposes during everyday life and unexpected emergencies.
For long-term storage:
- Keep it in a cool, dry place.
- Protect it from moisture by storing opened boxes in airtight containers.
- Rotate your supply periodically as part of your regular pantry organization.
Because it's inexpensive and regularly used around the house, rotating your stock is easy.
Final Thoughts
Emergency preparedness isn't always about buying expensive gear.
Sometimes the most valuable supplies are already sitting in your kitchen.
Baking soda is a perfect example.
For just a few dollars, you gain a versatile tool that can help with cooking, cleaning, hygiene, odor control, and certain household emergencies.
Preparedness is about making smart use of what you already have—and few household products work harder than a simple box of baking soda.

Baking soda has a long shelf life, especially when stored in a cool, dry place.

Can baking soda replace toothpaste?
In a short-term emergency, baking soda can help clean your teeth, but it is not a long-term replacement for fluoride toothpaste, which helps prevent cavities.
