Red sauce stains on plastic containers can be frustrating to remove, but several methods can help. One common suggestion is to use natural sunlight, which can bleach the stain over several hours. If you're dealing with a particularly stubborn stain, you could try using a mixture of vinegar and water, or baking soda and water, letting it sit, and then rinsing and washing the container. For very tough stains, some people recommend using bleach diluted in water, but be sure to thoroughly wash the container afterward to avoid any bleach residue. To prevent red sauce stains in the first place, you can create a barrier between the sauce and the plastic by using cooking spray, butter, or plastic wrap.

Soak in a bleach and water mixture
So, you've tried and failed to remove that red sauce stain from your plastic container, and now you're considering throwing it out. But wait! There's one more trick up your sleeve: the bleach and water soak. Here's a step-by-step guide to help you remove that stubborn stain and restore your plastic container to its former glory.
First, grab your bleach and water. For this method, the ratio of bleach to water is important. You only need a small amount of bleach; too much can damage the plastic. Mix one part bleach with three parts water in your plastic container.
Next, let the container soak. Depending on the severity of the stain, you may need to let it soak for several hours or even overnight. The bleach solution will work to break down the stain, so you can say goodbye to that unsightly red tint.
While you're waiting, there are a few things to keep in mind. Firstly, this method is most effective on light-coloured plastics. If your container is brightly coloured, the bleach may cause discolouration, so proceed with caution. Secondly, always work in a well-ventilated area when using bleach, and wear protective gloves if possible.
Once the soaking is complete, give the container a good rinse with warm water. If any stain remains, repeat the process. With this method, you may need to be patient and persistent, but it's worth it to rescue your plastic container from the brink!
So, there you have it! The bleach and water soak is a powerful tool in your stain-removal arsenal. While it may take some time and care, it can be an effective way to remove even the most stubborn of red sauce stains from your plastic containers.

Use baking soda, dish soap and water
To remove red sauce stains from a plastic container, a combination of baking soda, dish soap, and water is a great solution. This method is recommended by Becky Rapinchuck of the Clean Mama blog.
To make the baking soda-based solution, mix two tablespoons of baking soda, one teaspoon of water, and a quarter teaspoon of dish soap. You can adjust the quantities as needed, depending on the size of your container and the severity of the stain. Mix these ingredients in the stained container itself. Ensure that you mix them well to form a paste.
Once you have a paste-like consistency, use a scrubber to gently scrub the mixture inside the container. After scrubbing, let the paste sit in the container for at least 15 minutes. The longer you let it sit, the better, as this gives the solution more time to break down the stains.
After 15 minutes, rinse the container with water. If the stain is still visible, repeat the process until it disappears. You can also try filling the container with water, adding dish soap and a paper towel, sealing the lid, and shaking it vigorously.

Soak in vinegar and water
Vinegar is an effective agent for removing tough stains from fabrics and other materials. To remove red sauce stains from plastic containers, a mixture of vinegar and water can be used.
Firstly, it is important to dilute the vinegar with water. The mixture should be one part vinegar to three parts water. This diluted mixture can then be poured into the stained plastic container. The container should be filled with enough of the mixture to completely cover the stain.
The next step is to allow the container to soak. The length of soaking time will depend on the stubbornness of the stain. For less stubborn stains, the container should be left to soak for 15-30 minutes. For more stubborn stains, it may be necessary to leave the container to soak overnight.
After the container has soaked for the appropriate amount of time, the vinegar and water mixture can be discarded. The container should then be rinsed with clean water to remove any remaining residue.
It is important to note that vinegar should not be used in a washing machine, as it can destroy the seals if used continually.

Create an oil barrier with cooking spray
To remove red sauce stains from plastic containers, one effective method is to create an oil barrier with cooking spray. This method can be used both before and after staining.
Before using a plastic container for red sauce, you can apply a light coating of cooking spray inside the container. This additional layer acts as a barrier, preventing the sauce from staining the plastic. When it's time to clean the container, simply soak it with a grease-fighting dish soap to get rid of any excess oil.
If your plastic container is already stained with red sauce, you can still use cooking spray to remove the stain. Spray the interior of the container generously with cooking spray. Grab a clean, dry paper towel and wipe off any excess oil. The remaining oil will act as a protective barrier, preventing the red pigment from further staining the plastic. Once the oil barrier is created, you can proceed to clean the container with dish soap and water to remove the stain.
It's important to note that cooking spray is typically meant for non-stick cooking and is usually vegetable or canola oil-based. The oil helps to prevent the red pigment from adhering to the porous surface of the plastic.

Use a dishwasher
To remove red sauce stains from plastic containers, using a dishwasher can be an effective method. Here is a step-by-step guide:
Step 1: Soak the Containers
Before placing them in the dishwasher, it is recommended to soak the stained plastic containers in a sink filled with hot water and a generous amount of dish soap. Adding a splash of bleach to the water can also help loosen the stains. Let the containers soak for several hours or even overnight for the best results. This step helps to break down the grease and stains caused by the red sauce.
Step 2: Prepare the Dishwasher
Ensure your dishwasher is ready for use by checking that it is fully loaded with similar items. Running the dishwasher with a full load is more energy-efficient and practical. Check that the detergent cup is filled with a good quality detergent, preferably one designed to tackle tough stains, such as Dawn® Platinum. Its unique formula is designed to break down food messes while being gentle on plasticware.
Step 3: Place the Containers in the Dishwasher
After the containers have soaked, place them in the dishwasher, ensuring they are securely placed on the racks. If there are any particularly stubborn stains, you can use a sponge or scouring pad to give those areas a quick scrub before placing them in the dishwasher. Close the dishwasher door and start the wash cycle.
Step 4: Air Dry and Inspect
Once the dishwasher cycle is complete, carefully remove the plastic containers and place them on a drying rack. Allow them to air dry completely. After they are dry, inspect the containers for any remaining stains. If there are still some faint stains, don't worry—there are additional steps you can take.
Step 5: Sunlight Exposure (Optional)
If any light stains remain, you can utilize the power of sunlight to naturally bleach out the remaining discoloration. Place the containers on a windowsill that receives direct sunlight. Over time, the sunlight will help to fade the stains. This process may take several hours or even a few days, so be sure to check on the containers periodically.
Using a dishwasher in combination with these steps can effectively remove red sauce stains from plastic containers. Remember to always soak the containers beforehand and utilize a high-quality detergent to ensure the best results. With these steps, your plastic containers will be stain-free and ready for your next meal prep session!
