How to Get Smell Out of Plastic: Why Does My Tupperware Smell Like Regret?

Plastic is one of the most versatile materials in the world, but it has a notorious reputation for retaining odors. Whether it’s the lingering scent of last week’s spaghetti or the ghost of garlic haunting your lunchbox, getting rid of smells in plastic can feel like an impossible task. But fear not! This guide will walk you through a variety of methods to banish those stubborn odors and restore your plastic items to their former glory. And while we’re at it, let’s ponder why plastic seems to absorb smells like a sponge soaking up existential dread.


Why Does Plastic Hold Onto Smells?

Before diving into solutions, it’s worth understanding why plastic is so prone to trapping odors. Plastic is a porous material, especially when it’s not of the highest quality. Tiny microscopic holes and scratches on the surface can trap food particles, oils, and other odor-causing substances. Over time, these trapped particles break down and release unpleasant smells. Additionally, certain types of plastic, like polyethylene and polypropylene, are more susceptible to odor retention due to their chemical structure.


Methods to Remove Smells from Plastic

1. Baking Soda: The Odor Neutralizer

Baking soda is a classic odor-eliminating powerhouse. Its alkaline nature helps neutralize acidic odors, making it perfect for tackling stubborn smells in plastic containers.

  • How to Use:
    Mix 1-2 tablespoons of baking soda with warm water to create a paste or solution. Scrub the inside of the plastic container with the mixture using a sponge or cloth. Let it sit for a few hours or overnight, then rinse thoroughly. For extra stubborn odors, leave the baking soda dry inside the container overnight before rinsing.

2. Vinegar: The Natural Deodorizer

White vinegar is another household staple that works wonders on plastic odors. Its acidic properties help break down odor-causing molecules.

  • How to Use:
    Fill the plastic container with equal parts water and white vinegar. Let it soak for a few hours or overnight. Rinse thoroughly with soap and water afterward. If the smell persists, repeat the process or add a few drops of lemon juice for an extra boost.

3. Lemon Juice: The Freshness Enhancer

Lemon juice is not only a natural deodorizer but also leaves behind a fresh, citrusy scent.

  • How to Use:
    Squeeze the juice of one or two lemons into the plastic container, then fill it with warm water. Let it sit for a few hours before rinsing. For tougher odors, add a teaspoon of baking soda to the mixture.

4. Activated Charcoal: The Odor Absorber

Activated charcoal is highly effective at absorbing odors and impurities. It’s particularly useful for removing strong, persistent smells.

  • How to Use:
    Place a few pieces of activated charcoal inside the plastic container and seal it shut. Leave it for 24-48 hours, then rinse the container thoroughly. Repeat if necessary.

5. Sunlight: The Natural Disinfectant

Sunlight is a natural disinfectant and deodorizer. UV rays can help break down odor-causing compounds and kill bacteria.

  • How to Use:
    Wash the plastic container with soap and water, then place it in direct sunlight for several hours. Rotate the container to ensure all sides are exposed to the sun.

6. Coffee Grounds: The Aromatic Solution

Coffee grounds are excellent at absorbing odors and can leave behind a pleasant coffee scent.

  • How to Use:
    Place a handful of used coffee grounds inside the plastic container and seal it shut. Leave it for 24 hours, then rinse thoroughly. Be sure to clean the container well to avoid leaving behind coffee residue.

7. Dishwasher Detergent: The Heavy-Duty Cleaner

For particularly stubborn odors, dishwasher detergent can be a lifesaver. Its powerful formula is designed to cut through grease and grime.

  • How to Use:
    Add a small amount of dishwasher detergent to the plastic container and fill it with hot water. Let it soak for a few hours, then scrub and rinse thoroughly.

8. Freezing: The Cold Truth

Freezing can help neutralize odors by solidifying odor-causing particles, making them easier to remove.

  • How to Use:
    Place the plastic container in the freezer for a few hours. Once removed, wash it with soap and water to eliminate any remaining odor.

9. Essential Oils: The Aromatic Touch

Essential oils like tea tree, lavender, or eucalyptus can help mask and neutralize odors.

  • How to Use:
    Add a few drops of essential oil to a bowl of warm water and use it to wash the plastic container. Alternatively, place a cotton ball soaked in essential oil inside the container and seal it shut for a few hours.

10. Denture Tablets: The Unexpected Hero

Denture cleaning tablets are designed to remove stains and odors, making them perfect for cleaning plastic.

  • How to Use:
    Fill the plastic container with warm water and drop in 1-2 denture tablets. Let it sit for a few hours, then rinse thoroughly.

Preventing Future Odors

Once you’ve successfully removed the smell, take steps to prevent it from returning:

  • Avoid Storing Strong-Smelling Foods: Foods like garlic, onions, and curry are notorious for leaving behind strong odors. Use glass containers for these items whenever possible.
  • Wash Immediately: Don’t let food sit in plastic containers for too long. Wash them as soon as possible after use.
  • Use Liners: Consider using liners or parchment paper to create a barrier between the food and the plastic.
  • Air Out Containers: After washing, leave plastic containers open to air dry completely before storing them.
