What You'll Learn

Using a baking soda paste
To remove food grease from a plastic container using a baking soda paste, start by sprinkling a thick layer of baking soda on the bottom of the container. Next, slowly add warm water until you have a paste that is slightly thinner than toothpaste. You want it to be spreadable but not too runny.
With your fingers, a sponge, or a cloth, spread the paste all over the greasy surfaces of the container. Let the paste sit for around 5 minutes. If the grease is particularly stubborn, you can let it sit for up to 30 minutes.
Afterward, rinse the paste away with warm water. Make sure to wash away all the baking soda, using your fingers or a sponge to ensure none of it is left behind.
For even better results, scrub the container with the paste using a cloth or scrubbing brush. Gently buff the paste all over the greasy surfaces. Then, rinse with warm water and dish soap.

Soaking in a bleach solution
Bleach is a great option for removing grease and stains from plastic. It is important to note that bleach is toxic if ingested and can damage plastics if not used properly. Therefore, it is recommended to use diluted bleach solutions when cleaning plastic items.
To start, put on some protective gloves to avoid getting bleach on your skin. Then, fill a sink, bowl, or container with enough warm water to completely submerge the greasy plastic item. Add approximately one tablespoon of bleach per cup of water, ensuring the bleach is fully dissolved in the water.
Next, submerge the plastic item in the bleach solution. Make sure the plastic is completely covered by the solution. Allow the item to soak for at least an hour. For tougher stains, you can increase the soaking time to 5 to 10 minutes.
After soaking, remove the item from the bleach solution and rinse it thoroughly with plain water to remove any bleach residue. Finally, wash the item with soapy water and rinse again to ensure all traces of bleach are gone.
By following these steps, you can effectively use a bleach solution to remove food grease from plastic containers, leaving them clean and sanitized.

Applying vinegar
Vinegar is an effective way to remove grease from plastic containers. Its acidity helps break down grease and neutralise odours. Here is a step-by-step guide to applying vinegar to remove grease:
Step 1: Prepare the Vinegar Solution
Mix one tablespoon of vinegar with one cup of warm water. You can adjust the ratio depending on the size of your container, maintaining the 1:3 ratio of vinegar to water.
Step 2: Apply the Solution
Pour the vinegar solution into the greasy plastic container. Ensure that all greasy surfaces are coated with the solution. Alternatively, you can pour the solution into a spray bottle and spritz it onto the greasy areas.
Step 3: Let it Sit
Allow the vinegar solution to sit on the greasy surfaces for at least 30 minutes. This gives the vinegar time to break down the grease effectively. If you are dealing with particularly stubborn grease, you may want to let it sit for longer, up to one or two hours.
Step 4: Rinse and Clean
After the solution has had sufficient time to work, rinse the container with plain water to remove the vinegar and grease residue. If needed, use a small amount of mild dish soap and a soft cloth or sponge to gently scrub away any remaining grease. Rinse the container again with plain water to ensure all traces of vinegar and soap are removed.
Additional Tips:
- For extra greasy containers, you can add a few drops of dish soap to the vinegar solution before applying it.
- If you don't want to use pure vinegar, you can dilute it with water and add a few squeezes of lemon juice to enhance its degreasing power.
- Be cautious when using vinegar on plastic containers that have been used in the microwave, as the heat may have caused the plastic to become more porous and susceptible to absorbing liquids.
- Always rinse your plastic containers with warm water immediately after use to prevent grease from hardening and becoming more difficult to remove.
By following these steps and tips, you can effectively use vinegar to remove food grease from your plastic containers, leaving them clean and odour-free.

Shaking with paper towels
To start, put a little bit of dish soap and warm water into the stained container. The dish soap should be specifically designed to clean grease residue, as regular hand soap will not be effective. Then, take a paper towel and rip it into thirds or smaller pieces. The paper towel will help to absorb the grease. Add the paper towel pieces to the container and seal the lid tightly.
Now for the fun part: shake the container as hard as you can, in all directions, for at least a minute. If the grease streaks are still visible, keep shaking until the sides are clear. You can also dump, rinse, and repeat as needed. When done correctly, the grease will be absorbed into the paper towel, leaving your container completely clean.
This method is an effective and easy way to remove grease stains from plastic containers. It is also a great alternative to using harsh chemicals like bleach, which some people prefer to avoid in their kitchens.

Using cooking oil
Grease and oil are hydrophobic, meaning they repel water, which makes them challenging to clean. Leftover grease on plastic containers can attract bacteria and cause lingering odors. While it may seem counterintuitive, cooking oil can be used to clean greasy containers. Here is a step-by-step guide on how to use cooking oil to remove food grease from plastic containers:
Step 1: Apply Cooking Oil
Take a few drops of cooking oil and apply it directly to the greasy areas of the plastic container. You can use a sponge or cloth to spread the oil and ensure it reaches all the greasy surfaces.
Step 2: Scrub Gently
After applying the cooking oil, use a sponge, cloth, or scrubbing brush to gently scrub the greasy areas. The oil will help break down the grease, making it easier to remove. Scrub until you feel that the grease has loosened or lifted from the plastic surface.
Step 3: Wash with Dish Soap and Warm Water
Once you have finished scrubbing, it's time to remove the loosened grease. Wash the container with dish soap and warm water. You can use a sponge or cloth to scrub the container gently while rinsing it with warm water. Ensure that you rinse thoroughly until all traces of grease, oil, and soap are gone.
Tips and Variations:
- If you're concerned about using cooking oil due to its potential to leave a residue, you can opt for a natural oil like coconut oil instead.
- For heavily stained containers, you can create a paste with baking soda and water. Apply this paste to the greasy areas and let it sit for a few minutes before scrubbing and rinsing with warm water.
- Another natural option is to use vinegar, which helps break down grease. Create a solution of vinegar and water, soak a cloth in it, and scrub the greasy areas.
- For extremely stubborn stains, you can soak the container in a bleach solution (approximately 1 tablespoon of bleach per cup of water) for an hour or more, then rinse and wash with soapy water.
Remember to rinse your plastic containers immediately after use to prevent grease buildup and make cleaning easier.
