Use Bleach And Hot Water To Clean Stains From Tupperware Containers

Use Bleach And Hot Water To Clean Stains From Tupperware Containers

At some point we’ve all pulled a reusable plastic container out of the dishwasher and found that yesterday’s tomato soup has stained the plastic. Thankfully, there’s an easy way to clean those stains right out and make your Tupperware look like new.

The recipe, over at My American Confessions, goes like this: a quarter cup of bleach, a drop of dish soap and some tap water. Pour it all in the container and toss it in the microwave for about 40 seconds or until the liquid starts to bubble. Pull the container back out, let it stand until the water is lukewarm — this step is important — and then give it a good washing with soap and a sponge, or run it through the dishwasher.

The end product is twofold: your microwave is that much cleaner thanks to all of the steam, and the Tupperware container should be as good as new. It’s important to differentiate a stained container from a damaged one (you can tell because a damaged one is all rough on the inside), the latter of which shouldn’t be used for food or recycled.

If you baulk at the idea of microwaving bleach, one commenter at My American Confessions suggests using hot or boiling water and then adding bleach and dish soap to get the same effect — the important step is letting it all rest in the container and cool. If you’re no fan of bleach, we’ve previously covered another method that uses lemon juice instead.

  • I just fill the container with water and add around a teaspoon-full of one of those laundry enzyme-soakers, such as Di-San from Aldi. Dissolve it in the water and just let it soak for thirty minutes [more or less], and then wash normally. Never had any problems with that system.

  • Bleach needs the contact time, not the heat. High temps will make it evaporate out.

    If you want to boil it in the microwave, just use the detergent, soap works better in high temperature, bleach doesn’t.

  • Becareful when mixing bleach with detergent, you seriously don’t want to mix any detergent with acid or ammonia component, just saying. When bleach is heated and start to decompose, it’ll give you Sodium chlorate, that thing is very nasty for you if ingested, so make sure you rinse well.
