Plastic food containers are a convenient way to store food, but they can be tricky to keep truly clean. Over time, plastic breaks down and can release microplastics into food. This can happen when plastic containers are washed in the dishwasher or heated in the microwave, as high heat exacerbates microplastic shedding. Bleach and vinegar are popular cleaning agents, but they can also eat away at plastic if used too frequently. Baking soda, hand sanitizer, and sugar scrubs are gentler alternatives that can effectively remove stains and odours. To reduce the risk of ingesting microplastics, it is recommended to use glass or porcelain food storage containers and transfer food from plastic containers as soon as possible.

What You'll Learn
Bleach can eat away at plastic
Bleach is a powerful disinfectant that can be used to clean plastic containers. However, it should be used with caution as it can eat away at plastic if left for too long. Bleach is a potent chemical that can effectively remove even the worst odours and discolouration from plastic containers. However, it is important to follow certain guidelines when using bleach for cleaning. Firstly, never mix bleach with any other cleaners, chemicals, or natural products as this can be dangerous. Always use bleach in a well-ventilated area and wear gloves for protection.
When using bleach to clean plastic containers, it is important to follow the correct procedure. First, allow the container to soak in a bleach solution for 1-2 hours. Avoid handling the container unnecessarily during this time. Set a timer to remind yourself to empty the container after the allotted time. If bleach is left in the container for an extended period, it can eat away at the plastic, causing damage. After soaking, thoroughly wash the container with clean water and ensure that all traces of bleach are removed.
To further clean the container, a small amount of dish soap can be added, and the container can be gently scrubbed with a soft sponge. It is important to avoid using abrasive tools like steel wool as they can scratch the plastic. Rinse the container again with clean water and allow it to dry. This process will effectively sanitise and deodorise the plastic container while also removing any discolouration.
While bleach is a powerful cleaning agent, it should be noted that it may not be the best option for removing tough stains on plastic. In some cases, stains may persist even after a prolonged soak in a bleach solution. Alternative methods, such as using baking soda, hand sanitiser, or sugar scrubs, can be more effective for stain removal. These methods are gentler on plastic and are less likely to cause discolouration or damage over time.
In conclusion, bleach can be used to clean plastic containers, but it should be handled with care. By following the recommended procedures and not leaving bleach in contact with the plastic for too long, individuals can effectively sanitise and deodorise their containers without causing damage. However, for stain removal, alternative methods may be more suitable and less likely to negatively impact the plastic over time.

Vinegar and water remove stains
While plastic containers are great for storing leftovers, they can be a pain to clean. Soap and water are generally the safest options for cleaning plastic. However, for tough stains, vinegar and baking soda are popular choices.
Using Vinegar and Water to Remove Stains
A vinegar and water solution can be used to remove stains from plastic containers. The recommended ratio is one tablespoon of vinegar per cup of water. Pour the solution into the container and let it sit for one to two hours. Then, wipe the container clean, rinse it with water, and dry it. This method is also effective for removing mild yellowing and mildew smells from clothes.
Other Methods for Removing Stains
- Baking soda and water paste: Create a paste by mixing two tablespoons of baking soda with half a cup of warm water. Apply the paste to the stain and scrub gently. Baking soda can also absorb unwanted odours.
- Sugar scrub: Cover the bottom of the container with sugar, add some dish soap and a few ice cubes, and let it sit for an hour. Then, scrub the container with a damp cloth and rinse with warm water.
- Hand sanitizer: Pour hand sanitizer over the stain and let it sit for about 45 minutes. Wipe the container clean and wash it with soap and water.
- Dish soap: For grease stains, apply dish soap to the stain, let it sit for an hour, and then pour boiling water over the stain.
- Fels-naptha: For ink, cooking grease, car grease, or blood stains, spritz the stained area with water and use the bar to scrub the fabric. Then, wash the item immediately.
It is important to note that acidic products like vinegar can affect the colour of plastic and slowly "eat" it away if used frequently. Therefore, it is recommended to dilute vinegar with water for lighter stains.

Baking soda and water cut through stains
It is important to note that plastic containers should be washed by hand with soap and water, as they can be easily worn down by harsh cleaning agents. Bleach, for instance, should be used with caution, as it can eat away at plastic if left for too long.
Baking soda and water are an effective alternative for cutting through stains on plastic containers. Baking soda is a versatile and effective cleaning agent that can be used to tackle a wide range of tasks, from unclogging drains to removing tough stains and neutralizing odors. Its absorbent properties make it ideal for removing stains and odours from containers.
To make a baking soda paste, simply mix one tablespoon of water with two tablespoons of baking soda. The paste should have a thick, spreadable consistency. You can adjust the consistency by adding more water or baking soda. This paste can then be applied to the stain and left to dry. Once dry, the paste can be brushed away, and the container can be washed as usual.
For particularly stubborn stains, you can substitute water with white vinegar to create a baking soda paste. The acetic acid in vinegar reacts with the baking soda to lift stains. This mixture is also great for brightening whites. The paste should be scrubbed into the stain and left for 10 to 15 minutes before being rinsed with cool water.
Baking soda can also be used to remove stains from fabrics. For fresh stains, sprinkle baking soda onto the wet stain and leave it overnight. The stain and any related odours should be gone by morning, and the clothing can be washed as usual. For older stains, a baking soda and water paste can be applied to the stained area and left to dry. The dried paste can then be brushed away, and the garment can be washed per the care label instructions.

Hand sanitiser removes stains
It is important to keep plastic containers clean and stain-free, especially if they are being reused for storing food. Soap and water are generally considered the safest for cleaning plastic. However, stains can be stubborn and may require additional treatments.
Hand sanitiser, for example, is an effective stain remover. Its main ingredient, alcohol, can tackle a variety of stains, including pen marks, hot sauce, grease, grass stains, and makeup. To use hand sanitiser for stain removal, liberally apply it to the stain and let it sit for 5 to 10 minutes. Then, wipe it clean and wash the container with soap and water. This method was tested on a plastic container stained with turmeric, and the stain was completely removed.
Another popular method for removing stains from plastic containers is using baking soda. Baking soda can cut through stains and absorb unwanted odours. To use this method, create a paste by mixing two tablespoons of baking soda with half a cup of warm water. Apply the paste to the stain and scrub the container gently. This method may require a larger batch of paste for bigger containers or multiple containers.
Additionally, a mixture of sugar, dish soap, and ice cubes can be used to remove stains from plastic containers. Cover the bottom of the container with sugar, add dish soap, and a few ice cubes, then let it sit for an hour. After that, scrub the container with a damp cloth and rinse it with warm water.
While these methods are effective for removing stains, it is important to note that certain products can affect the colour of plastic and even slowly "eat" it away if used frequently. For example, vinegar is great for removing odours, but it may not be as effective for removing stains and can discolour plastic over time. Similarly, bleach is potent for removing stains and odours, but if left on plastic for too long, it can eat away at the material. Therefore, it is recommended to use soap and water for regular cleaning and resort to stronger stain removal methods only when necessary.

Microwaving plastic increases microplastic shedding
Plastic containers are a convenient way to store food, but they can be tricky to keep stain and odour-free. There are various methods for cleaning them, including using soap and water, vinegar, bleach, baking soda, sugar, and even hand sanitiser. However, it's important to be cautious when cleaning plastic containers, as some cleaning agents like vinegar and bleach can affect the colour of plastic and even "eat" it away slowly if used frequently. Additionally, abrasive cleaning tools like steel wool can scratch the plastic.
While plastic containers are convenient for food storage, they may not always be the safest option, especially when it comes to microwaving. Microwaving plastic containers can increase the shedding of micro- and nanoplastics into food. This process of microplastic shedding is accelerated by heat, and microwaving plastic can result in the release of millions or even billions of microplastic particles. This was demonstrated in a study where baby food containers from two popular US brands were microwaved, leading to the release of 4.2 million and 1.2 billion particles per square centimetre of plastic, respectively.
The health risks associated with ingesting these microplastics are a significant concern. In a study, human embryonic kidney cells were exposed to the microplastics shed by baby food containers. After two days, about 75% of the kidney cells died, indicating potential toxic effects on the body. While this study used a higher concentration of microplastics than what a baby would typically ingest, it highlights the potential dangers of microplastic exposure over time.
To minimise the risk of ingesting microplastics, it is recommended to avoid microwaving plastic containers. Instead, opt for containers specifically manufactured for microwave use, such as those made of glass or ceramic. These alternatives are safer options for heating food and reducing potential health hazards.
It is worth noting that even at room temperature, plastic containers can release micro- and nanoplastics into food. However, the rate of shedding increases significantly with higher temperatures. Therefore, it is advisable to follow food safety guidelines and use containers suitable for their intended purpose to protect your health and minimise the presence of harmful microplastics in your food.

Frequently asked questions
Some solutions used for super cleaning, such as vinegar, bleach, and other acidic products, can slowly eat away at plastic if used frequently or left on for too long. It is recommended to dilute vinegar and acidic products with water and to not leave bleach in a plastic container for longer than 1-2 hours.
Plastic containers can leach microplastics and chemicals, such as bisphenols and phthalates, into food. These chemicals have been linked to various health issues, including cancer, weakened immune systems, and developmental delays in children. Additionally, high heat can break down plastics, increasing microplastic shedding, so plastic containers should not be microwaved or put in the dishwasher.
To prevent stains and odors, it is recommended to wash plastic containers immediately after use and avoid heating them. Lining containers with parchment, wax paper, or tinfoil can also create a barrier between the plastic and the food, making cleanup easier. For stubborn stains, a paste made from baking soda and water can be effective.
