Onions are a staple ingredient in kitchens around the world, but storing them in plastic containers can be a challenge due to their strong odour. The reason onions leave such a potent smell is that plastic is porous, meaning it has tiny holes that absorb odour-causing molecules from food. Luckily, there are several easy ways to remove onion odours from plastic container lids, including using baking soda, vinegar, lemon juice, dry coffee grounds, charcoal, and sunlight.
| Characteristics | Values |
|---|---|
| Baking soda | Sprinkle a generous amount of baking soda inside the container, close it, and let it sit overnight. Wash it with warm, soapy water afterward. |
| Vinegar | Soak the container in vinegar and water for a few hours. |
| Lemon juice | Mix lemon juice with water and soak the container in the mixture. |
| Activated charcoal | Put activated charcoal in a sealed container and leave it for a few hours or overnight. |
| Coffee grounds | Place coffee grounds in the container and let them sit overnight. |
| Newspaper | Crumple up some newspaper, put it in the container, seal it, and let it sit for 24-48 hours. Wash the container afterward. |
| Sunlight | Place the container in direct sunlight for a few hours. |
| Vanilla extract | Pour 2-3 tablespoons of water and a few drops of vanilla extract into the container, seal it, and let it soak for a few hours. |
| Salt | Place a pinch of salt in the container and let it sit overnight. |

What You'll Learn
Soak lids in vinegar
Soaking plastic container lids in vinegar is an effective way to remove onion odours. The acetic acid in vinegar breaks down the compounds responsible for strong smells, leaving your plastic lids odour-free.
To use this method, fill your sink with enough vinegar to completely cover the lids. Allow the lids to soak for several hours. If the onion smell is particularly strong, you can leave them to soak overnight.
After soaking, wash the lids with hot, soapy water. Use a good dish soap and scrub the lids well to ensure that any lingering odour molecules are removed. Rinse the lids thoroughly and dry them with a clean cloth or leave them to air dry.
If the onion smell is very strong, you may need to repeat the process. Alternatively, you can try combining vinegar with other odour-fighting agents, such as baking soda. Simply mix vinegar and baking soda to form a paste, then rub it all over the lids. Leave the paste to sit for a few hours before washing it off. This combination approach may be more effective for stubborn onion odours.

Use lemon juice and water
Lemon juice is a great natural deodorizer and cleaner. Its citric acid works to break down odors and any leftover oils that might be holding onto the onion smell. To use lemon juice and water to remove onion odors from plastic container lids, follow these steps:
Step 1: Prepare the Lemon Juice and Water Solution
- Squeeze the juice of one lemon into the container.
- Add equal parts water.
- Toss in the squeezed lemon halves as well.
Step 2: Soak the Container
Let the container lid soak in the lemon juice and water solution for a few hours.
Step 3: Rinse and Dry
- After soaking, rinse the container lid thoroughly with water to remove any remaining odor and lemon juice scent.
- Wash and dry your container lid thoroughly before using it again.
For stronger onion odors, you can also try soaking the container lid in the lemon juice and water solution overnight. Additionally, leaving the container lid in direct sunlight for a day or two after cleaning can help eliminate any lingering odors. Remember to rotate the lid occasionally to ensure even exposure to sunlight.

Baking soda and water paste
Baking soda is a super-efficient and budget-friendly option to get rid of onion odours from plastic container lids. It works by attracting and neutralizing the smelly molecules. To use baking soda, mix it with a little water to make a paste, then rub it all over the surface of the container lid. You can also sprinkle a generous amount of baking soda inside the container, close the lid, and let it sit overnight.
After letting the paste sit for a while, wash the container lid with warm, soapy water. You can also try using a combination of baking soda and vinegar, leaving it for a few hours to get rid of the smell.
If you're looking for a milder approach, you can mix lemon juice with water and soak the container lid in the solution. The natural enzymes in lemon juice will help break down any leftover oils that may be holding onto the onion smell. Another option is to use activated charcoal, which has tiny holes that trap smelly molecules. Place a small bag or a few pieces of activated charcoal inside the container, close it tightly, and leave it for a few hours or overnight.
For a quicker fix, you can try using a spray like Dawn Powerwash Spray or Pooph, which are designed to remove odours from plastic containers.

Leave in direct sunlight
Sunlight is a very effective way to remove onion odours from plastic container lids. The ultraviolet rays, fresh air, and open space will all work together to neutralise and lift away the odour.
To do this, place the container lid outside in direct sunlight on a sunny day. You can place it on a windowsill, and even leave the window open so the fresh air can help cast out the odour. Rotate the lid occasionally to ensure even exposure to the sun. Leave the lid out for one to two days. This method will also help to lighten any food stains.
While sunlight is an effective method for removing odours, it will slightly shorten the plastic's life. This is because it is the UV rays that break apart the scent molecules, and this process can damage the plastic.
If you want to avoid UV damage, you could try another method first, such as using baking soda, vinegar, or lemon juice.

Seal with activated charcoal
One of the easiest ways to remove onion odours from plastic containers is to use activated charcoal. This natural deodorizer has tons of tiny holes that trap smelly molecules. All you need to do is put a small bag or a few pieces of food-safe activated charcoal in your plastic container and close it up tight. Leave it alone for a few hours or overnight, and let the charcoal do its magic. The charcoal will absorb the onion smell and leave your plastic container odour-free.
For the best results, use fresh charcoal and keep the container sealed. You can also use this method as a preventative measure by keeping a small bag of activated charcoal in your container whenever it's not in use. This will help neutralize any lingering odours and keep your container smelling fresh.
Activated charcoal is a great option for those who want a quick, easy, and effective solution to removing onion odours from their plastic containers. It's also versatile and can be used to absorb odours from other sources as well.
In addition to using activated charcoal, there are other methods you can try to remove onion odours from your plastic containers. For example, you can soak the container in a mixture of lemon juice and water, as the natural enzymes in lemon juice help break down odours and any leftover oils that may be harbouring the onion smell. Alternatively, you can use vinegar and water, as the acetic acid in vinegar breaks down the compounds responsible for nasty odours.
