What You'll Learn

Use undiluted dish soap and warm water
To remove oil stains from plastic containers, one effective method is to use undiluted dish soap and warm water. This method is particularly useful for plastic containers that come into direct contact with oils or greasy substances. The warm water helps to loosen the oil's grip on the plastic surface, making it easier to wash away.
To begin, fill the stained plastic container about a third of the way with warm water. Then, add a generous amount of undiluted dish soap—do not dilute the soap with water, as this will make it less effective against tough grease. For added friction, you can also add a few pieces of ripped-up paper towel. Secure the lid of the container tightly and shake vigorously for about 45 seconds to a minute. The shaking motion helps to agitate the liquid inside, ensuring that the soap comes into contact with all parts of the container.
After shaking, remove the lid and rinse the container with warm water. If done correctly, you should notice a significant improvement in the container's cleanliness, with most, if not all, of the oil stains removed. If any oily residue remains, repeat the process, ensuring that you shake the container for a full minute and agitate it in all directions.
This method is simple, effective, and cuts down on cleaning time. It is a useful technique to have in your arsenal, especially when dealing with stubborn oil stains that seem impossible to remove.

Soak in vinegar
Soaking plastic containers in vinegar is an effective way to remove oil stains and restore them to their original condition. White vinegar, in particular, is a natural acid that breaks down oils, loosening their grip on plastic surfaces. This makes it easier to wash away the oil residue.
To use this method, create a solution of vinegar and water. The recommended ratio is one tablespoon of vinegar per cup of water. However, some sources suggest using a higher concentration of vinegar, such as 30% cleaning vinegar or even pure vinegar. After mixing the solution, pour it into the stained container and let it sit for at least an hour. Some sources recommend letting the solution sit for up to two hours for better results.
After soaking, scrub the container gently with a sponge or brush and then rinse it thoroughly with water. This process should effectively remove the oil stains and eliminate any lingering odours. It is important to note that vinegar may not be as effective for removing stains caused by carotene-rich foods, such as turmeric.
Additionally, vinegar can be used in combination with other household products for enhanced results. For example, one can mix vinegar with baking soda, creating a paste to scrub onto greasy surfaces. This method provides an additional abrasive element to the degreasing power of vinegar.

Apply toothpaste
Toothpaste can be an effective way to remove oil stains from plastic containers. Its abrasive nature helps scrub away stubborn residues without damaging the plastic. To use this method, start by applying a small amount of toothpaste directly onto the stained area of the container. Then, use a soft brush or cloth to gently work the toothpaste in circular motions. The mild abrasiveness of the toothpaste will help lift the oil, while its cleaning agents break down the grease.
It is important to note that this method may not be suitable for all types of plastic, as some surfaces may be more delicate than others. It is always recommended to test the method on a small area first to ensure it does not cause any damage.
After applying the toothpaste, it is crucial to rinse the container thoroughly with water. This will help remove any residual toothpaste and grease, ensuring that the container is clean and ready for reuse.
Additionally, you can place the container in the sun for half an hour after cleaning it. This will help remove any remaining moisture and eliminate any lingering odours.
Toothpaste is a surprising yet effective solution for removing oil stains from plastic containers. By following these steps, you can easily lift away oil residues and restore the container's clean appearance without resorting to harsh chemicals or scrubbing.

Use baking soda
To remove oil stains from plastic containers using baking soda, you can try the following methods:
Baking Soda and Water
First, take out the contents from the box. Sprinkle 1 to 2 tablespoons of baking soda in the bottom of the container and slowly add warm water to make a paste. The paste should be thick but spreadable. Smoosh the paste onto the stained areas of the container, then let it sit for 30 minutes. After 30 minutes, wipe the paste around with a damp cloth, rubbing the stained areas well, then rinse with dish soap and warm water. Repeat if necessary.
Baking Soda, Water, and Vinegar
Mix one part vinegar and one part baking soda with three parts water and add a squeeze of dish soap. Soak a cloth in the solution and scrub the greasy plastic surfaces. Rinse off the mixture with plain water.
Baking Soda and Hot Water
Add one teaspoon of baking soda to hot water and mix in a vessel. Put the plastic container in this mixture and leave it for half an hour. Finally, clean it with a brush to remove the oily stains.
Dish Soap, Baking Soda, and Water
Add dish soap and warm water to the container, close the lid, and shake vigorously. Wash by hand with soap and water. Drop a few drops of soap on the container, rub it in with your hands, and rinse. Repeat if necessary.

Try lemon juice
Lemon juice is an effective way to remove oil stains from plastic containers. It acts as a natural bleaching or whitening agent, removing stains and disinfecting the container.
To use this method, start by squeezing lemon juice over the stained area. You can also rub a cut lemon over the stain, ensuring the lemon juice soaks into the plastic. Leave the lemon juice on the stain for around 15 minutes. If your container has yellowed, you can place it in the sun for a few hours to enhance the bleaching effect.
For extra scrubbing power, sprinkle salt over the lemon juice. The salt will act as a natural scrub, helping to dislodge the stain particles. After allowing the lemon juice to soak into the stain, scrub the container with the leftover lemon or a sponge, then rinse thoroughly with warm water.
Lemon juice can also be combined with vinegar for a powerful cleaning solution. Mix three teaspoons of lemon juice and two teaspoons of vinegar with two litres of water. Soak the stained container in this mixture for an hour, then scrub with a brush and rinse.
