Tomato-based sauces, such as marinara, can leave stubborn stains on plastic containers. These stains are caused by a naturally occurring chemical compound called lycopene, which adheres to and discolours plastic. However, there are several methods to remove these stains using common household products.

Using baking soda
Tomato gravy stains on plastic containers are notoriously difficult to remove. However, baking soda is an effective, nontoxic solution that can help scrub away those stains.
First, ensure your plastic container has reached room temperature. Next, remove any leftover food particles or stuck-on messes from the container. This is important because you want the entire surface of the container's interior to be exposed to the baking soda.
Now, it's time to make the baking soda paste. Add two tablespoons of baking soda to a small bowl. Slowly add water and stir until you achieve a thick but spreadable paste. You can also add a couple of drops of dish detergent or lemon essential oil to enhance the cleaning power of the paste.
Apply the paste to the stained interior of the container, covering all the stained areas. Let the paste sit for up to 30 minutes, or longer if you're dealing with older or tougher stains.
After the waiting period, scrub the paste into the stain with a sponge or stiff-bristled brush. Rinse the paste away with warm water and wash the container as usual.
If the stain persists, repeat the process or try soaking the container in a solution of distilled white vinegar and water for 12 to 24 hours before attempting to scrub the stain again with the baking soda paste.

Using vinegar
Vinegar is an effective way to remove tomato gravy stains from plastic containers. It is a cheap, easily accessible, and non-damaging method.
Firstly, ensure the container is at room temperature. If you have just microwaved the container, allow it to cool down. Remove any leftover food particles and stuck-on messes from the container.
Next, fill the container with equal parts warm water and vinegar. The amount of liquid you use will depend on the size of your container. For example, for a small container, you may use one cup of water and one tablespoon of vinegar. For a larger container, fill it halfway with warm water and then pour in enough vinegar to fill it to the top.
Allow the container to soak for 12 to 24 hours. The longer you leave it, the more effective the method will be. After soaking, rinse and wash the container with dish soap to remove any remaining stains and the vinegary smell.
For tougher stains, you can scrub the container with vinegar and baking soda. Wear rubber gloves and pour one to two teaspoons of baking soda over the stained plastic. Then, pour half a cup to one cup of vinegar on top. The mixture will foam and expand. Scrub the container with a stiff-bristled brush or sponge until the stain disappears. Rinse and wash the container once you are done scrubbing.
You can also try using a stronger concentration of vinegar if the stain persists. One source suggests using 5% distilled white vinegar for 12 hours, followed by 30% cleaning vinegar.

Using dish soap
To remove tomato gravy stains from plastic containers using dish soap, follow these steps:
Soaking Method
Fill the plastic container with warm water and add a few squeezes of mild dish soap. Drop in a folded paper towel, close the lid, and shake the container for about a minute. Remove the paper towel and rinse the container. If the stains are still there, try the next method.
Soaking and Scrubbing Method
Mix two tablespoons of baking soda, one teaspoon of water, and a quarter teaspoon of dish soap in the stained container. Scrub the paste into the stain and let it sit for at least 15 minutes. Then, rinse and wash the container.
Vinegar and Dish Soap Method
Pour one cup of hot water and one tablespoon of white vinegar into the container. Let the mixture soak for 12 to 24 hours, then rinse and wash the container with dish soap.
Sugar and Dish Soap Method
Sprinkle one to two teaspoons of sugar into the container. Squirt a small amount of dish soap on top of the sugar. Add six ice cubes and fill the container with cold water. The sugar will absorb the oil from the tomato gravy, and the ice cubes will help separate the tomato and oil, making it easier for the sugar to work.
Dishwasher Method
Wash the stained plasticware with a sponge and a concentrated dish liquid, just as you would with any dish. Place the container on a drying rack and let it air dry. Once dry, move the container to a windowsill with direct sunlight. The sunlight will naturally bleach out the stain.
It is important to note that you should avoid rough scrubbing as it can damage the plastic. Also, always ensure the container is at room temperature before cleaning and remove any food particles to ensure all stained areas are exposed to the cleaning solution.

Using lemons
Lemons are a great natural way to remove tomato stains from plastic containers. The acidity in lemons helps to cut through the oil in the stains. Here are some methods to try:
Lemon and scrub
Cut a lemon in half and rub the cut surface onto the stain, gently squeezing to release the juice. Scrub the stain until it disappears, then wash the container as usual.
Lemon and sunlight
Rub lemon juice onto the stained area of the container, then place it in direct sunlight for one to two days. The sun and lemon juice work together to remove the stain. This method is best for those who live in hot climates, as intense, direct sunlight is needed.
Lemon and dish soap
Add a couple of tablespoons of mild dish soap to the container, then fill it with hot water and close the lid. Shake the container vigorously for up to a minute, then discard the soapy water. If the stain remains, add a little dish soap to a non-abrasive sponge and scrub the area. Finally, wash the container as usual.
Preventing stains
To prevent tomato stains, always cool food down before storing it in plastic containers. Additionally, when reheating food in the microwave, remove the plastic lid.

Using hydrogen peroxide
To remove tomato gravy stains from plastic containers using hydrogen peroxide, follow these steps:
Firstly, ensure that the plastic container is at room temperature. If you have just microwaved food in the container, allow it to cool down completely. Remove any food particles and stuck-on messes from inside the container to ensure that all stained areas are exposed to the cleaning solution.
Next, wear protective gloves and ensure that the area you are working in is well-ventilated. Fill the container with hydrogen peroxide, ensuring that the stained area is completely covered. Allow the peroxide to sit in the container for at least thirty minutes to up to 24 hours, depending on the severity of the stain.
After this, carefully pour out the hydrogen peroxide and thoroughly clean the container to remove any trace of it. Wash the container with soap and hot water, scrubbing gently with a sponge or soft cloth. Repeat this process a few times if necessary.
Finally, ensure that you wash the container at least two to three times to remove any remaining hydrogen peroxide. Ingesting hydrogen peroxide can lead to vomiting or gastrointestinal problems.
Note: Do not use hydrogen peroxide if you have recently cleaned the container with vinegar without thoroughly washing it afterward, as these two substances can create a dangerous gas when mixed.
