Using hot water and dish soap

To clean oily plastic containers with hot water and dish soap, start by wiping the containers with a paper towel to remove as much oil as possible. Then, fill your sink or a basin with hot water and add a dash of dish soap. Submerge the containers in the soapy water and let them soak for a few minutes. You can also use a sponge soaked with hot, soapy water to scrub and wipe away any remaining grease. If your containers are stained, you can try making a paste with baking soda and water, smearing it over the stained areas, and letting it sit for about 30 minutes before wiping it away with a damp cloth and rinsing the container with hot water and dish soap.

Another method is to fill the container with hot water and a small amount of dish soap, place the lid on tightly, and shake vigorously for about a minute. Then, remove the lid and rinse the container with hot water. If your containers are very greasy, you can also try using a more aggressive degreasing solution like vinegar, lemon juice, or baking soda after washing them with hot water and dish soap.

It's important to note that not all dish soaps are created equal, and some may be more effective at cutting through grease than others. Additionally, while hot water is important for breaking down grease, be sure to check that your plastic containers can withstand the heat before submerging them in hot water or using hot water to wash them.

Soaking in bleach

To wash oily plastic containers with bleach, start by mixing a solution of bleach and warm water. The general recommendation is to use one tablespoon of bleach per cup of water. However, some sources suggest using two teaspoons of bleach per gallon of water for a milder bleach solution.

Before soaking the container in the bleach solution, it's important to remove any excess oil or grease from the surface. Use a paper towel or a reusable cloth to wipe down the container and get rid of as much surface grease as possible.

Once the container is relatively grease-free, you can fill it with the bleach solution or pour the solution into a sink or bowl large enough to submerge the container completely. Allow the container to soak for at least an hour. For tougher stains, you may need to let it soak for up to 45 minutes.

After soaking, rinse the container thoroughly with plain water to remove the bleach solution. It's important to ensure that all traces of bleach are gone. Then, wash the container with soapy water and rinse again. You can use a sponge or cloth to scrub the container gently during this step.

Finally, dry the container completely. You can use an absorbent towel to wipe it down, or simply let it air dry with the lid off. It's important to keep the lid off until the container is completely dry to prevent the growth of mould and mildew.

Applying baking soda

To clean oily plastic containers with baking soda, first wash the container with warm water and dish soap. Next, sprinkle a layer of baking soda into the container and use a soft sponge to work the baking soda around the container. Rinse the container well and repeat this process until it is clean and odour-free.

For stubborn stains, you can make a thick paste from baking soda and water. Sprinkle two tablespoons of baking soda into half a cup (120ml) of warm water and stir the mixture until it reaches the consistency of toothpaste or peanut butter. Spread the paste over the stained areas of the container and let it sit for 15 to 30 minutes. After this, wipe the paste around with a damp cloth, rubbing the bottom well, and then rinse the container with dish soap and warm water.

You can also use a solution of vinegar and baking soda to clean greasy plastic containers. Mix one part vinegar, one part baking soda, and three parts water, adding a squeeze of dish soap. Soak a cloth in the solution and scrub the greasy plastic surfaces. Finally, rinse the container with plain water.

Lemon can also be used in combination with baking soda to clean and deodorize containers. After sprinkling the container with baking soda, use half a lemon as a sponge, rubbing the baking soda into the surface of the plastic. Rinse well and dry thoroughly before storing.

Using vinegar

Vinegar is a great option for removing tough stains and odours from plastic containers. It is naturally antimicrobial, killing bacteria that may have grown on old food. Its acidity also helps break down grease and neutralise odours.

To use vinegar to clean your plastic containers, start by removing any large pieces of leftover food from the container. Then, give the container a preliminary rinse with hot water. Drain and shake out any excess water.

Next, fill the container with a mixture of vinegar and water. A common ratio is 1 tablespoon of vinegar per 1 cup of water. You can also add a squeeze of fresh lemon juice to help brighten discoloured plastic and leave it smelling pleasant. Close the container and shake vigorously, or let the solution sit for 30 minutes to an hour.

After the vinegar solution has had time to work, pour it out and rinse the container with clean water. If desired, add a few drops of liquid dish detergent and scrub the container with a sponge or stiff-bristled brush. Rinse the container again with clean water to remove any traces of soap.

For particularly stubborn stains, you can try using undiluted dish soap. Apply the soap directly to the oily spots and rub it in with your fingers or a damp sponge.

Always make sure to rinse and dry your plastic containers thoroughly after using vinegar to remove any residual vinegar smell or taste.

Rubbing alcohol

Oils and fats used in cooking can leave stubborn grease stains on plastic containers. Rinsing them with hot water is often not enough to remove the oily residue, which can attract bacteria, cause lingering odours, and even ruin the container.

One way to remove oily stains from plastic containers is by using rubbing alcohol. First, wipe off as much surface grease from the container as possible with a paper towel or reusable cloth. Then, pour some diluted rubbing alcohol over the stain or onto a cloth and rub it onto the affected area. Let the alcohol soak for a few minutes. Finally, rinse the container with water and wash it with dish soap to remove any remaining alcohol. You can also use alcohol-based hand sanitiser instead of rubbing alcohol, applying it to the stain and letting it sit for around 45 minutes before rinsing and washing.

Another method for removing oily stains from plastic containers involves using a mixture of vinegar and baking soda. First, wipe away any excess grease with a paper towel or cloth. Then, create a paste by mixing baking soda with water until it has a toothpaste-like consistency. Apply the paste to the stained areas of the container and let it sit for 20–30 minutes. After the paste has had time to work, wipe it away with a damp cloth, rubbing thoroughly to lift away the stains. Finally, wash the container with dish soap and warm water and let it dry.

It is important to note that some of these methods may not be suitable for delicate plastics, as they can cause the material to melt, warp, or become cloudy. Always test a small area first and use caution when handling potentially harmful substances like bleach.
