Got odors? mustard powder eliminates odors

Powdered mustard has been the “go-to deodorizer” among canning enthusiasts for decades.

Got odors?

Need to deodorize canning jars or plastic containers?

Use mustard powder to get rid of pesky stale odors when you want to reuse a jar or plastic container … lids, too.

  • 1 tsp of mustard powder
  • 1/4 cup water

Shake in the jar for a couple of minutes and then transfer to another jar.

If need be, use a stronger solution. Try a weaker solution, it might just work.

The many uses of mustard powder:

  • Garbage can: soak a dishcloth, sponge or paper towel, wipe down the inner walls of a garbage can.
  • Towels: soak stale dishcloths and towels, and then put them in the washing machine.
  • Sponges: soak sponges, rinse well.
  • Ziptop baggies: swish out used (or new) ziplock baggies.
  • New containers: swish out any brand new plastic container that has that unwanted new-plastic smell.
  • Cutting boards: wipe down cutting boards, especially after cutting onions, rinse well.


It deodorized armpits

Seriously — I was doing a food demo at Atherton Appliance store. I tried the ol’ wipe-the-pits-with-a-soapy-paper-towel trick, but that didn’t work. AHA! I remembered this canning jar deodorizer trick … and thankfully they had a well-stocked spice drawer. I had success with a wet paper towel, sprinkled with powdered mustard.

Storage and shelf life:

Store for up to a week in the refrigerator in an airtight container just-big-enough to hold the amount of liquid –as you should do with EVERYTHING that you store (see note, below). After a week or so, it –ironically– has an off-putting smell, and there’s no way you’ll want to use it.

Storage tip:

Store leftovers in a container that just fits the amount that you have. An over-sized container will have an air pocket above the food which allows for faster oxidation to occur. Then, if you use half of the leftovers, then move the food to a smaller container to fit the right amount, to reduce the amount of air trapped in the container.
