How to Remove Stains from Tupperware

Tupperware is a beloved kitchen staple for many households. These durable plastic containers come in a variety of sizes and shapes to store leftovers, pack lunches, and organize the pantry. However, over time, Tupperware can become stained and discoloured, especially when used to store strongly coloured foods like tomato sauce, curries, or berry-based dishes.

While Tupperware is designed to be long-lasting, those stubborn stains can be tough to remove, leaving your once vibrant containers looking old and dingy. But don’t worry, there are several effective methods you can try to get your Tupperware looking as good as new again. In this comprehensive guide, we’ll walk you through the best techniques for removing stains from Tupperware, whether they’re fresh or have set in over time.

We’ll cover everything from simple home remedies using everyday ingredients to specialized cleaning products made specifically for Tupperware. By the end, you’ll have all the tips and tricks you need to keep your Tupperware in tip-top shape. Let’s dive in!

Common Tupperware Stains and What Causes Them

Before we get into the stain removal methods, it’s helpful to understand the most common types of Tupperware stains and what causes them. This will give you a better sense of which cleaning approach is likely to be most effective.

Here are some of the most frequent Tupperware stains and their sources:

Stain TypeCause
Tomato-based stainsBlueberries, blackberries, raspberries, and other dark-coloured berries can leave behind purple, blue, or red stains that are notoriously difficult to remove from plastic.
Curry and turmeric stainsCurries and other Indian or Thai dishes often contain turmeric, a vibrant yellow spice that can leave stubborn stains on Tupperware. The stain is caused by the natural dyes in the turmeric.
Berry stainsSpices like curry powder, paprika, chilli powder, and cumin can also discolor Tupperware over time.
Coffee and tea stainsDrinking coffee or tea directly from Tupperware containers can lead to unsightly brown stains, especially around the rim.
Grease and oil stainsStoring fatty foods like fried chicken, french fries, or oily sauces in Tupperware can result in stubborn grease stains.
Stains from strong spicesSpices like curry powder, paprika, chilli powder, and cumin can also discolour Tupperware over time.

It’s worth noting that some stains are more persistent than others. For example, tomato-based and turmeric stains tend to be more challenging to remove compared to coffee or tea stains. Knowing the source of the stain can help you select the most appropriate cleaning method.

Preventing Tupperware Stains in the First Place

Before we delve into stain removal techniques, let’s discuss some proactive steps you can take to prevent Tupperware stains from occurring in the first place:

  1. Rinse immediately after use: As soon as you’re done using a Tupperware container, give it a quick rinse with warm, soapy water. This helps lift any residue before it has a chance to set in and stain the plastic.
  2. Avoid storing strongly coloured foods: If possible, try to avoid storing highly pigmented foods like tomato sauce, curries, or dark berries in your Tupperware. Instead, opt for glass or ceramic containers for these types of foods.
  3. Use stain-resistant Tupperware: Many modern Tupperware products are made with stain-resistant materials that are less prone to discolouration. Look for containers labelled as “stain-resistant” or made from copolyester or BPA-free plastic, such as Rubbermaid Brilliance Food Storage Containers.
  4. Line containers with paper towels: For particularly messy or strongly coloured foods, you can line the Tupperware with a paper towel before adding the food. This can help absorb any liquid or dyes that might otherwise stain the plastic.
  5. Avoid using Tupperware in the microwave: The high heat of the microwave can set in stains and make them harder to remove later on. Instead, reheat food in a separate dish and then transfer it to the Tupperware container.
  6. Clean Tupperware promptly: Don’t let stained Tupperware sit for days or weeks before cleaning it. The sooner you address the stain, the easier it will be to remove.

By implementing these proactive measures, you can significantly reduce the likelihood of stubborn stains developing on your Tupperware in the first place. However, even with the best prevention efforts, stains can still occur. That’s where our comprehensive stain removal tips come in handy.

Simple Home Remedies for Removing Tupperware Stains

If you’re faced with a stained Tupperware container, don’t worry – there are several effective home remedies you can try using common household items. Here are some of the most popular and successful methods:

Baking Soda and Vinegar

Baking soda and vinegar are a dynamic duo when it comes to stain removal. The abrasive nature of baking soda helps scrub away tough stains, while the acidic vinegar helps break down and lift the discolouration.

To use this method, simply sprinkle a generous amount of baking soda into the stained Tupperware container. Then, pour in enough white vinegar to create a paste-like consistency. Let the mixture sit for 15-20 minutes, then scrub the container with a clean sponge or cloth. Rinse thoroughly with warm water.

Lemon Juice

The citric acid in lemon juice can be highly effective at removing stains from Tupperware. Simply squeeze the juice of a fresh lemon directly into the stained container, coating the entire surface. Let it sit for 30 minutes to an hour, then scrub and rinse clean.

For extra stubborn stains, you can also try rubbing a lemon wedge directly on the affected areas before rinsing.

Denture Tablets

Believe it or not, denture-cleaning tablets can work wonders on Tupperware stains. The fizzing action and cleaning agents in the tablets help break down stuck-on residue.

Simply drop 1-2 denture tablets into the stained container, fill it with warm water, and let it sit overnight. In the morning, scrub the container and rinse it clean.

Baking Soda Paste

Creating a simple baking soda paste is another highly effective home remedy. Mix 2-3 tablespoons of baking soda with just enough water to form a thick paste. Spread the paste over the stained areas and let it sit for 15-30 minutes before scrubbing and rinsing.

The abrasiveness of the baking soda helps lift and remove stubborn stains.

Salt and Lemon

For a natural, gentle abrasive, try using a mixture of salt and lemon juice. Sprinkle a generous amount of salt into the stained Tupperware, then squeeze in the juice of half a lemon. Use a clean sponge or cloth to scrub the mixture over the stained areas. Rinse thoroughly.

The coarseness of the salt combined with the acidity of the lemon makes for an effective stain-busting duo.

These home remedies are great for tackling fresh stains or lighter discolouration. However, for set-in, stubborn stains, you may need to turn to some more heavy-duty cleaning methods.

Advanced Stain Removal Techniques for Tupperware

If the simple home remedies aren’t cutting it, there are a few more advanced techniques you can try to remove deeply set-in Tupperware stains:

Bleach Solution

A diluted bleach solution can be an effective way to tackle those extra stubborn stains. Mix 1 tablespoon of bleach per 1 cup of warm water. Soak the stained Tupperware container in the solution for 15-30 minutes, then scrub and rinse thoroughly.

Be sure to use caution when working with bleach, as it can be harsh on skin and eyes. Wear gloves and work in a well-ventilated area.

Baking Soda and Hydrogen Peroxide

For stains that just won’t budge, try a paste made from baking soda and hydrogen peroxide. Mix 2-3 tablespoons of baking soda with enough 3% hydrogen peroxide to form a thick paste. Spread the paste over the stained areas and let it sit for 30 minutes to an hour before scrubbing and rinsing.

The hydrogen peroxide acts as a powerful oxidizing agent to break down and lift the stain.

Enzymatic Dishwasher Detergent

Enzymatic dishwasher detergents contain specialized enzymes that are designed to break down and remove stubborn food stains. Fill the stained Tupperware with warm water and add a small amount of enzymatic detergents, such as Cascade Platinum ActionPacs. Let it soak for at least 30 minutes before scrubbing and rinsing.

You can also try running the Tupperware through a full dishwasher cycle using this type of detergent.

Baking Soda and Vinegar Soak

For extra stubborn stains, try soaking the Tupperware in a baking soda and vinegar solution overnight. Fill the container with warm water, then add 2-3 tablespoons of baking soda and 1/4 cup of white vinegar. Let it sit for 8-12 hours before scrubbing and rinsing.

The extended soak time allows the solution to penetrate and break down the stain.

Specialty Tupperware Cleaners

If you’ve tried all the home remedies and are still struggling with stains, there are also specialized Tupperware cleaning products on the market. Look for cleaners that are specifically formulated to remove stains from plastic food storage containers, such as Fit Tupperware Cleaner.

These products often contain a combination of gentle abrasives, degreasers, and stain-lifting agents to tackle even the toughest discolouration.

With a little elbow grease and the right cleaning technique, you can revive even the most stained Tupperware containers and get them looking brand new again. The key is identifying the type of stain you’re dealing with and using the most appropriate cleaning method.

Remember, prevention is also key – practice good Tupperware maintenance habits to avoid stubborn stains in the first place. By following these tips, you can keep your Tupperware collection in tip-top shape for years to come.
