Prepping is all about planning ahead, and a key part of this is ensuring that the supplies and equipment that you store have multiple uses and redundancies, not only to save on space but to maximize how useful your supplies are in a real emergency situation.

Being able to rely on multiple sources of information, food, power, water and other essentials such as chemicals, medical equipment is critically important for bolstering your chances of surviving effectively when SHTF.

One of the most reliable and overlooked prepping supplies you may not have even considered is baking soda.

This humble chemical has a range of weird and wonderful uses and is pretty much the ultimate prepping solution.

While it may not be purpose-made for any one of its many uses, in a pinch baking soda can help you prepare food, clean, treat medical issues and a host of other important survival uses, despite the fact that most preppers will see it more as a luxury for baking than anything else.

In this guide, we’re going to look at just how flexible and effective baking soda is, as well as how long it lasts, how to store it effectively, and the best types available so you can make sure you stretch your baking soda to the max and get as much use out of it as possible.

We’ve also compiled a list of some of the best uses for baking soda, to prove beyond any doubt just how useful it is, and to give you some ideas and reminders of some key supplies you may have forgotten or niche needs that baking soda can be used to handle.

But first, let’s establish what baking soda actually is, and what makes this humble baking product kind of badass…

What Is Baking Soda?

Baking soda or sodium bicarbonate is a chemical compound that has the formula NaHCO3, and is a salt that is crystalline, white, solid, and soluble in water. It is often available in a very fine powder form and is found fairly widely in nature at natural mineral springs.

It is one of the best known and widely used kitchens and household products in the world and is commonly used for various purposes from baking to cleaning, however it has many additional uses.

It was first manufactured in the US in 1846, and there have been many brands that have produced the product since, under various names and for various uses.

It is inexpensive despite its utility, making it a great supply for preppers to use, however, don’t get it confused with baking powder, as this is a different product and has some key differences.

For example, baking powder isn’t just sodium bicarbonate, but also includes additional ingredients such as calcium acid phosphate, sodium aluminum phosphate, or cream of tartar and isn’t suitable for use in the same general way as baking soda.

Baking soda has some disinfectant capabilities and is also a fairly effective anti-fungal treatment, meaning it has many uses that are both practical and suitable for emergency situations.

How Long Does Baking Soda Last?

Baking soda lasts for a considerable amount of time, with big brands such as Arm and Hammer suggesting their version of baking soda can officially last for 3 years, however as with most things storage conditions can play a huge role in how effectively something will last.

Baking soda generally doesn’t ‘go bad’ as the salt inside it tends to discourage the growth of fungus and the like, however, baking soda can lose potency over time, and this is the main issue with storing this product for extended periods.

The best thing to do is to rotate out your supplies and ensure that any supplies which are starting to potentially lose their potency are used in general day-to-day household tasks and replaced with a fresher version of the product for storage which allows you to always keep a long term supply.

It’s also a good idea to test your baking soda to make sure it is still potent, and this is a relatively simple process.


Mix a cup of hot water with a teaspoon of vinegar and add a spoonful of baking soda or place a tablespoon of vinegar or lemon juice in a dish and add a quarter teaspoon of baking soda.

With either of these tests, you can tell if the baking soda is still functioning as expected, as it will immediately begin to fizz and produce bubbles as the chemicals react.

As the potency decreases over time, the bubbles and fizz will become less excited, and eventually, there will be no fizz at all as the baking soda becomes totally expired. This can take many years, however, so it’s not likely that this becomes a serious long-term issue.

Best Storage Conditions

The best storage conditions for baking soda are ideally an air-tight, water-tight container stored in a cool dry environment.

Baking soda loses its potency as it absorbs natural moisture from the air or odors, so using these techniques can massively reduce the process of expiration and make your baking soda last longer, or almost indefinitely.

It can be purchased in various sizes and containers, but you should consider using a sealed container especially when you’ve opened the original container, as these original containers are usually cheap and unsuitable for safe long-term storage.

Plastic pouches work quite well and pack down nicely for saving space, while plastic buckets with airtight lids and metal cans provide the best seal and longevity. Look at your climate and your local conditions as well as the space you have available to decide how best to store your supplies.

How Much Should I Store?

One of the biggest challenges for preppers is to determine how much of something should be stockpiled. This goes from bullets to bandages, from food to fuel, and space is finite so it’s very difficult to balance everything out correctly.

Baking Soda The All-Around Prepping Solution

For staple supplies and things that have various practical uses, a larger stockpile is generally advisable due to the versatility of the product, but it’s largely a matter of personal preference.

It’s also likely that you will use far more of these supplies than during normal life, so storing extra and erring on the side of caution is likely for the best.

Take a look at these recommendations for a rough idea of how much baking soda you need to store.

  • Food prep and cooking (if you also have a separate store of baking powder) – 1lb per person, per year
  • Food prep and cooking (with no other leavening agents stockpiled) – 3lbs per person, per year
  • Personal hygiene – 2lbs per person, per year
  • Medicine and first aid – 1lb per person, per year
  • Cleaning and deodorizing (per household) – 5lbs per year
  • Miscellaneous – 1lb per person per year

As you can see, just for a single person during SHTF a lot of baking soda can be used, but this is because it fulfills so many needs and does so many jobs.

This means you should keep a significant amount of baking soda stockpiled and correctly stored.

Generally, at least 10lbs per person per year is the minimum you should be looking for, with some redundancy ideally. Luckily it’s relatively inexpensive, so while it is indispensable it is also easy to keep stocks up, for now at least!

Best Type Of Baking Soda To Store?

Baking soda comes in many different varieties and brands, and some have additives and other things you don’t want in your baking soda.

Look for versions that are pure or use as few additives as possible to ensure that you have the longest-lasting and most flexible version of baking soda available.

The Best Uses For Baking Soda When SHTF

Preppers will be able to make use of baking soda in a variety of ways and these will be incredibly helpful for people who want to be totally self-sustaining and able to work with a limited number of resources to maintain a good quality of life.

Bug bite And Sting Relief

The disinfecting and anti-inflammatory nature of baking soda makes it ideal for treating stings and bites. Simply create a paste with a little water and apply it to the affected area.

Random Additional Uses For Baking Soda

Outside of the main uses for baking soda, there are additional random uses that you may not have considered, but these really show just how versatile this product is and allow you to use it in an emergency or for other random uses you may have overlooked.

Baking soda can be used to extinguish small grease fires by smothering the flames and killing the fire’s access to air, however, this should only be done in a real emergency as it will take a lot of your supply to effectively stop a fire.

Using up your baking soda is much better than burning down your shelter or risking your family’s lives, however!

Drain Unclogger

Clogged drains can be smelly and potentially unsanitary, which can open the door to disease and other nasties that can seriously affect your survival chances and quality of life.

Use some baking soda, around half a cup, mixed with a cup of vinegar, and pour it into the clogged drain. Allow this to sit for around 10 to 15 minutes before rinsing thoroughly with boiled water.

Weed Killer

Use some vinegar and baking soda to kill annoying weeds, but take care not to use this technique near crops or on your vegetable patch as this can damage your soil and your other plant life which you’re relying on for long-term food supplies.

Use in very small amounts directly on the weeds, ideally away from other important crops and plant life.

Bug Killer

Ants and roaches can be deterred by baiting them with baking soda and vinegar, keeping you safe from a potential morale-sapping infestation.

Battery Maintenance

Batteries are used extensively during survival scenarios, in shelters, as well as in vehicles.
