5 Useful Things to Know About Removing Smell from Plastic Containers
Removing smell from plastic containers can be a daunting task, especially when they’ve been used to store pungent foods like fish or onions. But don’t worry, we’ve got you covered. Whether you’re looking to reuse old takeout containers or simply want to get rid of that pesky smell in your favorite Tupperware, we’ll explore the most effective methods to leave your plastic containers smelling fresh and clean.
Understanding Why Plastic Containers Retain Smell
Plastic containers can absorb odors from the food they store due to the porous nature of plastic. This means that tiny molecules from the food can penetrate the plastic material, leaving a lingering smell. Additionally, bacteria and mold can grow on the surface of the container, especially if it’s not properly cleaned and dried. These microorganisms can produce compounds that contribute to the unpleasant odor.
Simple Methods to Remove Smell from Plastic Containers
Before we dive into more advanced techniques, let’s start with some simple methods to remove smell from plastic containers:
Baking soda and water: Make a paste with baking soda and water, and apply it to the interior of the container. Let it sit for 30 minutes to an hour before rinsing with warm water. The abrasive nature of baking soda helps to neutralize and absorb the odor.
Vinegar soak: Fill the container with equal parts water and white vinegar. Let it soak for several hours or overnight. The acid in the vinegar helps to break down and eliminate odor-causing molecules.
Dish soap and hot water: Wash the container with dish soap and hot water. This method is effective for removing surface dirt and bacteria that can contribute to the smell.

Advanced Techniques for Stubborn Smells
If the simple methods don’t work, it’s time to bring out the big guns. Here are some advanced techniques to remove stubborn smells from plastic containers:
The Power of Activated Charcoal
Activated charcoal is a natural odor absorber. Place a small piece of activated charcoal in the container and let it sit for a few hours or overnight. The charcoal will absorb the odor molecules, leaving the container smelling fresh.
Hydrogen Peroxide Treatment
Hydrogen peroxide is a strong oxidizing agent that can help to break down and eliminate odor-causing molecules. Apply hydrogen peroxide to the interior of the container and let it sit for 30 minutes to an hour before rinsing with warm water.
