Tips For Storing Baking Soda

Is there a reason NOT to store baking soda in an airtight container? I was just wondering because it always comes in a cardboard box that doesn’t really seal shut instead of a carton with a snap on plastic lid (like baking powder).

I’ve been having a problem with my baking soda going “bad” I do a lot of canning this time of year and as a result, my kitchen (in fact my whole house – small single story) gets quite humid at times. I know that baking soda absorbs moisture from the air and this reduces its potency. As a result, I keep having quick bread failure. I know now, after a lot of wasted ingredients, to always “test” my baking soda first. I know baking soda is cheap, but I hate to keep buying a new box every time I want to make a batch of cookies or quick bread. So, I thought I should start storing it in a ziplock bag or plastic container. BUT was wondering if there was a reason it shouldn’t be stored air tight. I mean why doesn’t Arm & Hammer package it in an air tight container?

    I keep old pickle or salsa jars (or any old glass or mason jar would work) and store my baking soda in them. I have never had any problems. I like to buy stuff in bulk and then store them that way. Maybe Arm and Hammer packages it that way to cut down on costs.

  2. Annie says

    I live in Australia, which can get fairly muggy and humid. it’s a diiferent brand, but the baking soda here also comes in a box (that NEVER opens properly!), I keep it in a ziplock bag in a plastic container (tupperware). It’s never gone bad for me that way.

  3. CharlieAnn says

    I agree with Dacia and Annie. I have stored by baking soda for years in a jar with a tight fitting lid and have had know problems with it. An I keep it to a year or better if I have bought a bulk size bag of it.

  4. Brooke says

    Something my mom has done for as long as I can remember is to store both baking soda and salt in Tupperware containers with a tight fitting lid. When I set up my own kitchen over 15 years ago I bought two 14 oz. Rubbermaid bowls with lids from Wal-Mart – one for baking soda and one for salt. It makes it SO easy to measure baking soda or salt (without having to dump it out of a container with a little metal spout into a little measuring spoon). I store them in my spice cabinet and I’ve never had an issue with them going bad before I could use it all. And it can take a year or longer to use the whole container. Hope this helps someone!

    Maybe baking soda comes in boxes because they try to sell it as fridge freshener so they want the baking soda somewhat exposed so it can absorb odors. I think it probably came in boxes before that, though, but it has so many uses they may figure it just gets used up quickly and doesn’t need to be sealed.

    • Pat T. says

      Actually, the cardboard box is as old as Arm & Hammer soda…they just never changed it, like baking powder still comes in a round container. Did you know that the man who founded Arm & Hammer was named “Armand Hammer?” I met him once and never got over how they translated his name into the company name he founded. Neat, huh? The idea to use it in the fridge (and sink, etc.) came long after the cardboard box – but they do need to update the darn thing that won’t stay opened right.

  6. Becky says

    Sounds like you better keep your in an airtight container. Most BS loses effectiveness before most people would use it up, so there’s little need to package it airtight. It would just run up the cost of one of the most effective and cheap ingredients in any kitchn!

  7. Laura in Ohio says

    I also keep my Baking Soda and Baking Powder in a Mason jars (with lid and ring), as well as most of my bulk spices and sea salt. They stay very fresh, even in the hot, humid summer here in Ohio.

    Also better to keep these things away from the heat of your stove, and from sunlight. That spice rack over your hot stove will ruin the essential oils/flavor in herbs and spices…

  8. Joanna says

    When my baking soda is no longer ‘fresh’ for cooking purposes I use it for cleaning things that require a non-abrasive cleaner.

    Will pour some down the drain to freshen the pipes a bit – sometimes mixing it with some vinegar for a fuzzy freshening of the pipes.

    Will also use it with water as a mouthrinse/breath freshener.

    Have been known to sprinkle it on the carpet to help absorb the life smells that carpets have.

    And lastly…use it in the fridge to keep things from overpowering other foods. And when it has done its fridge duty…down the drain it goes…

    • Nana says

      Exactly my uses match Joanna’s. I am enjoying the freedom of baking soda as it is non fragrant. I also use it to clean the fridge and bathroom. The addition of vinegar makes it a powerhouse.

    i have found that Trader Joe’s sells baking soda that comes in the same kind of container that baking powder comes in. i really like this because the lip on rim of the container works well to level off you teaspoon. i think the people that designed those awful cardboard containers were trying to get people to stick the boxes in their fridges to “deodorize them”. while, actually, baking soda does not deodorize ANYTHING while just sitting in a box. the only way to use this as a deodorizer is to make it in to a paste with water and rub it all over something that smells, let it dry, then wash it off with soap and water. i use it on my wooden cutting boards and it works great. good luck with your canning.

  10. Pamela says

    On a side note, I have a favorite baking soda tip… I keep ‘old’ soda in a little bowl on my sink ledge. When I handle garlic or onions I pinch a bit and rub my hands in the soda under water to get off the smell. I also pinch it to rub on a fruit or vege to help scrub it clean of any sprays.

  11. BJ says

    I keep all my old peanut butter jars. Lots of kids, lots of peanut butter jars!! they are now made of plastic and make great storage containers for salt, baking soda, cinnamon and all the other kinds of things that I buy in bulk. I also use one in my sewing, craft room to throw all my broken sewing machine needles and used up exacto blades or razor blades from my scraper. Keeps us safe and when it is time to throw them away keeps the trash/recycling center people safe too.

  12. Jen says

    I took the label off of an old backing powder container and used it. I just wrote in marker – Baking Soda- and now I don’t have to worry about the box!

  13. Wanda Johnson says

    If you live in the country and have a septic tank, every few months dump a cup or two into your toilet and flush it. Try to do this at night and not flush the toilet til morning. My septic tank never needs cleaning for about 25 years. It keeps the tank active.

    Okay, was wondering about this, now that my bread is falling apart. Didn’t know what it could be. About the Armand Hammer, that guy didn’t start Arm and Hammer- he owned shares in it but it was around like 30 yrs before he was born.

  15. Lynda says

    I use one of those plastic Pamesan/Romano cheese containers with the dual flip top lids. Works great! One side is for sprinkling, which is good for cleaning sinks etc and the other side opens the top half way open and measuring spoons fit in and the lid provides a ‘leveling’ or scraping edge too! After reading these post, I’m thinking the bigger size would be good for salt too!
