How to de-stink Tupperware

How to de-stink tupperware - Ask Anna

How do I remove the plastic smell out of tupperware?  I’ve had my tupperware for a year and the plastic smell is still there.  What can I do to get rid of it?

Because of my great love for Arm & Hammer Baking Soda, and it’s ability to remove odors from everything, I knew that using baking soda would de-stink Tupperware!  Here’s what you will need:

White vinegar
Baking soda

Each piece of the tupperware will need to be completely submerged in the mixture so you will want to find something that is large enough for all of it to fit into.  If you don’t have anything like that you might have to clean the tupperware in phases.

(this tip is adapted from the tip I found here)
1. Pour 1 cup white vinegar into the bucket, sink, etc.

2. Add 1/4 baking soda and stir.

3. Next add the tupperware.  Don’t forget to add the lids too.

4. Boil enough water to cover the tupperware and then pour it over the vinegar, baking soda and tupperware.  Stir, mixing in the water.

5. Let soak for 24-48 hours.

When it has finished soaking remove it from the mixture and run it through a full cycle in the dishwasher.  If you don’t have a dishwasher hand wash them in hot water to remove the baking soda and vinegar.  Your tupperware will be clean and ready for use {and stink free!}.

Good luck and I hope you will finally get to use your new tupperware!

  1. I wonder if this would also help remove the yellowing from my old tupperware. I have set it out in the sun thinking that the sun would bleach it, but it did little if any good.

    The boiling water scares me. Instead of boiling water, i wouldsuggest warm water and set all in a warm place. It may take a little while. To remove the smell from New Turrerware I put 2 or 3 drops of Vanilla on a paper towel. Fold the paper towel so vanilla does not touch any surface. Seal and set aside for a couple weeks or longer if needed. I have tryed other methods, so far this was the best for me.

  3. To annemarie: try putting oxygen peroxide + baking soda, THEN putting it out in the sun..that should whiten it!

  4. Great technique for any smelly thing, I'm sure.Kimberly @ THE BROWN EYES HAVE IT

  5. Setting it out in the sun for a couple of days worked for me. You might try this first and see if it works for you. Good luck!

  6. Will this work on the plastic containers that have been in use for long. I'll try it out.We have a link-up party going on – Tea Time Thursdays @ Kreative Korner. I would really appreciate if you'd link up some of your awesome posts there. Hope to see you at the party.

  7. Am getting some smell in my tupperware bottle. i washed it with hot water and dishwasher liquid. still am getting the smell. could you please help me to get rid of the smell

    • I would try what this post says: submerge it in baking soda, white vinegar and water over night. See full instructions above.

  8. I don’t have that brand of baking soda here. So how much of baking soda should I use

    • I think all baking soda is pretty much equal. Just use as much as you need, I never measure anything, I just play it by ear! :)

    I left smoked salmon in Tupperware for longer than I care to say and now it smells even after I soaked it in white vinegar for a week and then washed it in hot water, dried it and then covered the bottom with baking soda. Any suggestions?

  10. Two questions.
    1/4 baking soda — 1/4 cup? 1/4 of box?
    Won’t boiling water warp the lids and possibly the bottom?
    The smell I am trying to get out is that one that comes as the tupperware ages. 20 year old container I store dry ingredients in now has a smell. I have tried cornstarch, baking soda, washing, anything I can think of.

      Hi, Jackie! I’m Anna’s assistant, Bethany. The amount of baking soda you would need is 1/4 cup. Thank you for asking! As for the lids, it should not warp the lids or the bottom of the container if it’s standard tupperware. If it were the thinner containers that are meant for only a few uses, I would test it out on a small section before pouring in all of the water, but it doesn’t sound like that is what you have since it’s 20 years old. Hope this helps!
