How Do You Clean Discolored Tupperware?

Since you’re reading a post on Tupperware stains, it’s safe to assume you’ve got some sorry looking containers in your cupboard. Don’t worry; all of the cleaning tips below are tough on even the peskiest stains.

How Do You Clean Tupperware With Baking Soda?

When it comes to cleaning Tupperware, baking soda is your best buddy. All you have to do is coat the bottom of your container with a layer of baking soda and add enough warm water to make a paste. Use a clean toothbrush to scrub the baking soda into the most challenging stains and let it sit for 15 minutes. Lastly, wash your baking soda paste and inspect for any remaining spots.

You could also try mixing a layer of baking soda with a few tablespoons of ">white vinegar for a deeper clean. As these two chemicals fizz, pop the lid on your Tupperware and give your container a few good shakes. After a few minutes, wash out this mixture and check for stains.

By the way, you could also use baking soda to get rid of stinky odors. Pour a quarter cup of baking soda in your container, pop on the lid, and let it sit overnight. On the next morning, throw away the baking soda and enjoy your terrific-smelling Tupperware.

Since baking soda is such a kitchen staple, you might want to consider buying in bulk online.

Can You Bleach Old Tupperware?

Yes, you can use bleach to clean old Tupperware containers. However, since bleach is exceptionally potent, you should reserve this chemical for extreme stains that don’t respond to baking soda, lemon juice, or white vinegar.

A simple way to clean with bleach is to fill your Tupperware with warm water and pour in one to two teaspoons of bleach. You could let this mix sit for anywhere between one to 12 hours before you pour it out. Whenever you’re ready, wash your Tupperware thoroughly with water and dishwashing detergent. If possible, let your Tupperware dry in direct sunlight before storing it.

When Cleaning Just Isn’t Enough – Tupperware “End Of Life” Issues

Although all the cleaning tips above can work wonders on stains, please remember plastic Tupperware products have a lifespan. In this final section, we’ll share a few suggestions on what to do with Tupperware that’s no longer fit for food.

Can I Exchange My Old Tupperware?

All Tupperware products have a limited lifetime warranty, which means you might be able to exchange them for new items. However, there are many stipulations you have to keep in mind before asking for a replacement.

For instance, any of the following scenarios don’t qualify for an exchange:

  • Damage from cleaning Tupperware in the dishwasher.
  • Signs of abuse or misuse.
  • The use of aerosol cooking sprays.
  • Evidence of harsh cleaning like the use of steel wool, bleach, or scouring pads.

Should You Throw Away Old Tupperware?

One of the downsides of using plastic containers is they have a shorter shelf-life than glass products. If your Tupperware shows signs of damage or severe warping, it might be time to throw them away.

However, there are many ways you could still get some use out of older Tupperware containers. For instance, a few thrifty folks use old Tupperware containers to organize nuts and bolts in their garage.

By the way, many Tupperware containers are approved for recycling. Check the bottom of your container for the numbers 1 or 2. Most recycling facilities accept these two plastics.

If you have specific questions about whether your Tupperware model is acceptable for recycling, you could always give the company a call at (800) 887-7379. You could also reach out to your municipality’s recycling facility for any further questions.

Are Glass Containers Less Stain-Prone Versus Plastic Tupperware?

If you’re getting rid of a few plastic Tupperware, you might be wondering whether to upgrade to glass. Although glass containers are a bit pricier than plastics, they have a few distinct advantages worthy of consideration.

Most significantly, glass containers are far less stain-prone versus plastic ones. Plus, since glass containers don’t warp in the dishwasher, they are far easier to clean than their plastic counterparts.

On the flip side, glass containers weigh more than plastic ones, making them a tad cumbersome to transport to the office. Also, since glass containers are quite fragile, they aren’t the best choice for clumsy kids (or adults for that matter!).

Now that glass containers are becoming increasingly popular; there are plenty of different sizes and styles to choose from online.
