Struggling with stubborn tomato sauce stains on your Tupperware? Even vigorous scrubbing often fails to restore them. Tomato sauce is notorious for clinging to plastic containers. Fortunately, as a cleaning expert with years of experience, I recommend this proven, natural method using lemon juice and baking soda—no harsh chemicals required.
Contents - 1 tablespoon lemon juice
- 1 tablespoon baking soda
- 1 sponge with an abrasive side
1. Sprinkle the baking soda at the bottom of the container.
2. Pour the lemon juice over it.
3. Let it fizz for a moment.
4. Gently scrub with the abrasive side of the sponge.
5. Fill the container with water.
6. Let it soak overnight.

And there you have it! Your Tupperware is now spotless and stain-free. This easy, natural, and cost-effective trick removes even the toughest baked-on tomato sauce. No more residue or sticky spots—your containers look like new. It even eliminates lingering tomato odors and works great on mold stains too.
The chemical reaction between baking soda and lemon juice creates a fizzing action that lifts and loosens tomato residues from the plastic. It also disinfects, degreases, and deodorizes effectively. Paired with the abrasive sponge, it ensures a deep clean, banishing odors like stale plastic smells.
