Tomato sauce stains on Tupperware can be stubborn and frustrating. That bright red color seems to cling to your plastic containers no matter how hard you scrub. But don’t worry! With a few simple household tricks, you can say goodbye to those tomato sauce stains for good. Here’s a friendly, step-by-step guide on how to get tomato sauce stains out of Tupperware so your containers look fresh and clean again.
Why Do Tomato Sauce Stains Stick to Tupperware?
Tomato sauce contains a pigment called lycopene, which is hydrophobic (water-repelling). This means it loves to cling to plastic surfaces, making stains tough to remove with just water. Plus, tomato sauce often has oils that help the stain set deeper into the plastic, especially if the container has been microwaved with the sauce inside. Heat can cause the oils and pigments to bond with the plastic, making stains more permanent.
Step-by-Step Guide to Remove Tomato Sauce Stains from Tupperware
1. Cool Down and Clean the Container First
If you just microwaved your Tupperware, let it cool to room temperature before cleaning. Remove any leftover food particles or stuck-on sauce to expose all stained areas.
2. Use Dish Soap and Hot Water with a Paper Towel Shake
– Add a squirt of liquid dish soap into the stained container.
– Fill it partially with hot water.
– Place a few folded paper towels inside.
– Close the lid tightly and shake vigorously for a couple of minutes.
This simple shaking action with soap, water, and paper towels helps loosen and lift the stain from the plastic.
3. Try a Baking Soda Paste for Tough Stains
Make a paste by mixing baking soda with a little dish soap. Smear this paste over the stained areas and let it sit for 15–30 minutes. Then scrub gently with a non-abrasive sponge and rinse. Baking soda’s mild abrasiveness and deodorizing power help break down the stain.
4. Use White Vinegar for Stubborn Stains
Fill the container with distilled white vinegar and let it soak for several hours or overnight. Vinegar’s acidity helps dissolve the tomato pigments stuck in the plastic.
5. Hydrogen Peroxide for the Most Stubborn Marks
If stains persist, fill the container with hydrogen peroxide and let it sit up to 24 hours. After soaking, rinse thoroughly and wash as usual. Hydrogen peroxide acts as a mild bleach and can remove deep stains without harsh chemicals.
6. Rub Butter Before Washing (Surprise Hack!)
Since lycopene is hydrophobic, rubbing a little butter around the stained areas before washing with dish soap can help break down the oily pigment. Then wash as usual and watch the stains disappear.
Tips to Prevent Tomato Sauce Stains in the Future
– Avoid microwaving tomato sauce in plastic containers. Heat causes the stain to set permanently.
– Use glass containers for tomato-based foods whenever possible.
– Line your Tupperware with plastic wrap before adding tomato sauce to prevent direct contact.
– Clean containers promptly after use to prevent stains from setting.
– Expose containers to sunlight for a few hours; natural UV light can help bleach out stains and odors.
