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 habit of absorbing and retaining odors. Whether it’s the lingering scent of last week’s spaghetti or the ghost of a garlic-heavy stir-fry, getting smells out of 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. Along the way, we’ll also ponder why plastic seems to have a personal vendetta against freshness.


Why Does Plastic Hold Onto Smells?

Before diving into solutions, it’s worth understanding why plastic is so prone to odor retention. Plastic is a porous material, especially when it comes to food storage containers. Over time, microscopic particles of food, oils, and spices can seep into these tiny pores, creating a lingering smell. Additionally, plastic is non-reactive, meaning it doesn’t break down or neutralize odors on its own. This makes it a perfect host for stubborn scents.


Methods to Remove Smell 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 ideal for tackling smells in plastic.

  • How to Use:
    • Fill the plastic container with warm water and add 1-2 tablespoons of baking soda.
    • Let it sit overnight, then rinse thoroughly.
    • For extra stubborn smells, create a paste with baking soda and water, scrub the interior, and let it sit before rinsing.

2. Vinegar: The Natural Deodorizer

Vinegar’s acidic properties make it an excellent counterbalance to alkaline odors. It’s particularly effective for removing strong smells like garlic or fish.

  • How to Use:
    • Mix equal parts white vinegar and water in the plastic container.
    • Let it sit for a few hours or overnight.
    • Rinse thoroughly with soap and water to remove any vinegar smell.

3. Lemon Juice: The Freshness Booster

Lemon juice not only removes odors but also leaves behind a fresh, citrusy scent. It’s perfect for tackling mild to moderate smells.

  • How to Use:
    • Squeeze the juice of one or two lemons into the container.
    • Add warm water and let it sit for a few hours.
    • Scrub the interior with a sponge or brush, then rinse.

4. Activated Charcoal: The Odor Absorber

Activated charcoal is highly porous and excellent at absorbing odors. It’s a great option for persistent smells that refuse to budge.

  • How to Use:
    • Place a few pieces of activated charcoal inside the plastic container.
    • Seal the container and let it sit for 24-48 hours.
    • Remove the charcoal and rinse the container.

5. Sunlight: The Natural Disinfectant

Sunlight is a natural disinfectant and deodorizer. UV rays can help break down odor-causing molecules trapped in plastic.

  • How to Use:
    • Wash the plastic item with soap and water.
    • Place it in direct sunlight for several hours or a full day.
    • Rotate the item occasionally to ensure all sides are exposed.

6. Coffee Grounds: The Aroma Masker

Coffee grounds are excellent at absorbing and masking odors. They’re particularly useful for removing strong smells like curry or spices.

  • How to Use:
    • Place a handful of used coffee grounds in the plastic container.
    • Seal the container and let it sit overnight.
    • Rinse thoroughly to remove any coffee residue.

7. Dish Soap and Hot Water: The Basic Clean

Sometimes, a thorough wash with dish soap and hot water is all you need to remove mild odors.

  • How to Use:
    • Fill the container with hot water and add a few drops of dish soap.
    • Scrub the interior with a sponge or brush.
    • Rinse thoroughly and air dry.

8. Denture Tablets: The Unexpected Hero

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

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

9. Freezing: The Cold Solution

Freezing can help solidify odor-causing particles, making them easier to remove.

  • How to Use:
    • Place the plastic item in the freezer for a few hours.
    • Remove and wash with soap and water.

10. Rubbing Alcohol: The Deep Cleaner

Rubbing alcohol is a powerful solvent that can break down oils and residues trapped in plastic.

  • How to Use:
    • Dampen a cloth with rubbing alcohol and wipe the interior of the container.
    • Let it air dry completely before using.

Preventing Future Odors

Once you’ve successfully removed the smell, it’s important to take steps to prevent future odors from taking hold.

  • Avoid Storing Strong-Smelling Foods: Foods like garlic, onions, and fish are more likely to leave behind odors.
  • Use Lids Properly: Ensure lids are tightly sealed to prevent odors from escaping and lingering in the container.
  • Wash Immediately: Rinse plastic containers as soon as possible after use to prevent odors from setting in.
  • Use Liners: Consider using liners or parchment paper for particularly pungent foods.

FAQs

Q: Can I use bleach to remove smells from plastic?
A: While bleach can disinfect plastic, it’s not recommended for odor removal as it can leave behind its own strong smell and potentially damage the plastic.

Q: Will microwaving plastic help remove odors?
A: Microwaving plastic is not recommended, as it can release harmful chemicals and may not effectively remove odors.

Q: How often should I deep-clean my plastic containers?
A: It’s a good idea to deep-clean plastic containers every few weeks, especially if you frequently store strong-smelling foods.

Q: Can I use essential oils to mask odors in plastic?
A: While essential oils can mask odors temporarily, they won’t eliminate the source of the smell. It’s better to use odor-neutralizing methods first.

Q: Why does my plastic water bottle smell like mildew?
A: Mildew smells are often caused by moisture trapped in the bottle. Make sure to dry your bottle thoroughly after each use and clean it regularly with vinegar or baking soda.
