Got odors? mustard powder eliminates odors

Powdered mustard has been the “talked-of-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.


Water and mustard powder:

I use a 6:1 ratio (6 parts water and 1 part mustard powder), wipe, swish, soak, let sit for 15 minutes, or until odor is gone.

The image, above, shows 3 tbls water and 1 tsp mustard powder in the bottom of a one-gallon plastic pail. I left it sit at the bottom for 15 minutes or so and then used a sponge to wipe down the sides. Then I poured the mixture into the lid and let it sit for 15 minutes.

Try a higher dilution, it might just do the job you are working on. Years ago, when I came across this trick the ratio was very low, had a higher measurement of mustard powder than what I use now. Over the years I kept diminishing the amount of mustard powder only because the amount in the bottle was less and less.


The many uses of mustard powder:

  • soak a dishcloth, sponge or paper towel, wipe down the inner walls of a garbage can.
  • soak stale dishcloths and towels, and then put them in the washing machine.
  • soak sponges, rinse well.
  • swish out used (or new) ziplock baggies.
  • swish out any brand new plastic container that has that unwanted new-plastic smell.
  • wipe down cutting boards, especially after cutting onions, rinse well.
  • armpits, seriously, this was tried during a very busy day when I was catering a dinner party, or was it during a food demo at Atherton Appliance store. Anyways, I tried the ol’ wipe-the-pits-with-a-soapy-paper-towel trick, but that wasn’t enough. Thank goodness I remembered this canning jar deodorizer trick … and thankfully they had a well-stocked spice drawer.


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 –funny to say– gets an off smell, and there’s no way you’ll want to use it.


A pantry and refrigerator storage tip for you:

Store everything, including leftovers, drinks, oils, liquids, solids — in a container that just fits the amount of substance that you have. An over-sized container will have an air pocket above the food substance and allows more, faster, oxidation to occur.

A jar of (condiment) with a only one tablespoon of food removed will last a much longer time compared to a jar with just a tablespoon of food left at the bottom of the jar.
