Motor oil can be difficult to remove from plastic containers, as it tends to leave behind a greasy, grimy film even after regular washing. To effectively remove motor oil from plastic containers, you can use a variety of household products and techniques. This includes using dish soap and warm water, baking soda, vinegar, lemon juice, toothpaste, or bleach. Soaking the container in warm water and soap, or a vinegar or bleach solution, can help loosen the oil's grip on the surface, making it easier to wash away.

What You'll Learn

Use a degreasing detergent or dish soap with hot water
To remove motor oil from plastic containers, you can use a degreasing detergent or dish soap with hot water. This method is particularly useful for items like plastic containers that come into direct contact with oils or greasy substances. Before turning to more aggressive degreasing solutions, wipe off as much surface grease from the plastic item as possible with a paper towel or reusable cloth. Then, fill the container with hot water and add a degreasing detergent or dish soap. Close the lid and shake the container vigorously to ensure that the soap and water combine to form suds. You can also use a sponge or cloth to apply the soapy water to the container and scrub the interior thoroughly.
The warm water helps to loosen the oil's grip on the surface, while the soap breaks down its molecular structure, making it easier to wash away. By allowing the plastic to soak for a sufficient amount of time, the stubborn oil stains will dissolve, leaving the plastic clean and ready for reuse without the need for harsh chemicals or scrubbing. After applying the soapy water, scrub the interior of the container thoroughly to ensure that the oil is removed. Rinse the container multiple times with plain water to remove any remaining traces of soap.
If the plastic container still has a greasy residue, you can try using a mixture of baking soda and vinegar to break down the oils. Prepare a thick paste of baking soda and water, aiming for a consistency similar to toothpaste or peanut butter. Spread the paste all over the greasy surfaces of the plastic item and let it sit for a few minutes to break down the grease. Then, gently scrub the surface with a soft cloth or sponge and rinse thoroughly with warm water.
It is important to avoid using harsh chemicals when cleaning plastic containers, as these can leach into the water and affect water quality. Instead, opt for gentle, natural degreasers like vinegar, lemon juice, or baking soda. These natural alternatives are effective at breaking down oils and restoring the plastic's clean appearance.

Apply a mixture of baking soda and vinegar to break down oils
To remove motor oil from plastic containers, one effective method is to apply a mixture of baking soda and vinegar. This process can break down oils and grease, removing stains and odours.
Firstly, it is important to wipe away any excess oil or grease with a paper towel or cloth. Then, prepare a mixture of vinegar and baking soda. The ratio should be approximately one part vinegar to three parts water, with baking soda added to form a paste. The paste should be similar in consistency to toothpaste or peanut butter.
Apply the paste to the stained areas of the container, ensuring all greasy areas are covered. Leave the paste to sit for around five minutes. The baking soda will begin to break down the grease, and its mild abrasiveness will help lift and absorb the oil. After a few minutes, scrub the paste gently with a sponge or soft cloth. Rinse the container thoroughly with warm water.
For particularly stubborn stains, you can try soaking the container in a mixture of vinegar and water before applying the paste. Simply fill a sink or large container with warm water and add vinegar, using the same ratio as before. Then, immerse the container in the solution for 15-30 minutes. After soaking, apply the baking soda paste and follow the steps above.
This method is an effective way to remove motor oil stains and odours from plastic containers without causing any damage.

Soak in a bleach solution
Soaking in a bleach solution is an effective method for removing motor oil stains from plastic containers. It is a good option for greasy plastic that is also stained. Before preparing the bleach solution, it is important to wipe off as much surface grease from the container as possible using a paper towel or a reusable cloth.
To prepare the bleach solution, fill a sink, bowl, or another container large enough to soak the plastic item with warm water and add a small quantity of bleach. The recommended ratio is approximately one tablespoon of bleach per cup of water. It is important to wear protective gloves and clothing to avoid splashes of the bleach solution.
Once the solution is ready, completely submerge the plastic container in the solution and let it soak for an hour or more. After soaking, rinse the container with plain water to remove the bleach solution. Then, wash the container with soapy water and rinse again to ensure all traces of bleach are removed.
It is important to note that this method is suitable for stained and greasy plastic items. For plastic items that are only greasy, a mixture of vinegar, baking soda, and dish soap may be a more suitable and gentle option.

Use toothpaste to scrub away residue
Motor oil can leave a stubborn residue on plastic containers that is difficult to remove with regular soap and water. One effective method to remove this residue is to use toothpaste. Toothpaste has mild abrasive properties that help lift and scrub away the oil residue without damaging the plastic.
To use this method, start by applying a small amount of toothpaste directly onto the stained areas of the plastic container. Use a soft-bristled brush or a clean cloth to gently work the toothpaste into the stained areas in circular motions. The mild abrasiveness of the toothpaste will help lift and break down the grease, while its cleaning agents will help dissolve it.
If the motor oil residue is particularly stubborn, you can let the toothpaste sit on the stained areas for a few minutes before scrubbing. This will give the toothpaste more time to penetrate and break down the grease, making it easier to remove. After scrubbing, rinse the container thoroughly with clean water to remove any residual toothpaste and grease.
For heavily soiled containers, you may need to repeat the process a few times to completely remove all the motor oil residue. It is important to rinse the container well between each application of toothpaste to gauge the effectiveness of the method and to ensure that all the residue is removed.
By using toothpaste to scrub away the residue, you can effectively remove motor oil from plastic containers without resorting to harsh chemicals or damaging the plastic. This method is simple, inexpensive, and utilizes easily accessible household items.
