Bleach solutions for breaking down tough stains
Bleach solutions are a powerful way to break down tough stains on plastic containers. However, it is important to exercise caution when using bleach, as it can irritate the skin and its fumes can be harmful if inhaled. Always wear gloves and use bleach in a well-ventilated area.
To make a bleach solution, mix one tablespoon of chlorine bleach with one cup of hot water. You can adjust the amounts as needed to fully cover the stain. Soak a sponge or cloth in the solution and apply it to the stained area of the container. Allow the solution to sit for at least 10-15 minutes, or up to 40-45 minutes for tougher stains. After the stain has been removed, thoroughly wash the container with hot, soapy water and let it air dry.
For an even stronger bleach solution, mix one part chlorine bleach with ten parts water. Apply this mixture to the stained area and let it sit for at least one hour or overnight. Be sure to wash the container extra thoroughly after using this stronger solution, preferably running it through the dishwasher, to ensure no bleach residue remains.
If you are concerned about using bleach on food containers, there are alternative methods to consider. Denture tablets, for example, can be very effective at removing stains from plastic. Dissolve two denture tablets or Alka-Seltzer in a cup of hot water and pour the solution into the stained container. Allow it to sit until the stain disappears, then rinse and dry the container.
Lemon juice is another natural alternative to bleach, as its acidity helps to lift stains from plastic. Squeeze lemon juice over the stained area or rub a halved lemon on the discolored areas. You can also try combining lemon juice with sunlight by leaving the treated container outside for a couple of days so the sun's UV rays can enhance the stain-removing effect.

Baking soda paste to loosen stains and odours
Baking soda is a natural ingredient that is gently abrasive and helps loosen stains and odours. It is also known as sodium bicarbonate or bicarb. To use it to clean your plastic containers, follow these steps:
First, add a couple of tablespoons of baking soda to the container. Then, add just enough warm water to form a paste. The paste should be thicker than a typical toothpaste; it should be spreadable but not runny. Next, spread the paste over the bottom and sides of the container, focusing on the stained areas. Let the paste sit for 30 minutes. After 30 minutes, wipe the paste around with a damp cloth, rubbing it well, then rinse with dish soap and warm water. Finally, wash the container with hot, soapy water and air dry.
If the baking soda removes the stain but not the odour, there is another step you can take. Crumple some newspaper and gently pack it into the container, then seal it with the lid. Let the container sit for 1-2 days, then discard the newspaper and wash the container with hot, soapy water.
In addition to baking soda, there are other methods to remove stains from plastic containers. These include using denture tablets, hand sanitiser, bleach, vinegar, lemon juice, or sugar.

Hand sanitiser to cover and remove stains
Keeping plastic containers stain-free can be challenging, especially when it comes to stubborn, set-in stains. While some people opt for a dishwasher or hand-washing, these methods may not always deliver the desired results. Here's where hand sanitiser comes in as a surprising but effective solution to cover and remove stains from plastic containers.
Hand sanitiser, with its high alcohol content, is a versatile cleaning agent that goes beyond hand sanitisation. Its stain-removing abilities are particularly useful for liquid stains that require a powerful cleanup. To use hand sanitiser for stain removal, follow these steps:
- Pour a generous amount of liquid hand sanitiser into the stained area of the container, ensuring complete coverage.
- Let the hand sanitiser sit for at least 45 minutes. The longer it sits, the better its stain-fighting action.
- After the waiting period, pour out the hand sanitiser. You'll notice that the stain has been lifted from the container.
- Use a soft cloth or paper towel to wipe away any remaining residue.
- Finally, wash the container with hot, soapy water and allow it to air dry.
It is important to note that this method is most effective for stains on the bottom of the container, as the hand sanitiser needs to completely cover the stain. Additionally, while hand sanitiser works well on certain types of stains, it may not be the best option for all stains. For older, deeply set-in stains, you might need to try alternative methods, such as using baking soda or bleach solutions.
By following these instructions, you can effectively use hand sanitiser to cover and remove stains from your plastic containers, restoring them to a like-new condition. Not only will your containers look cleaner, but this method will also eliminate any unpleasant odours, making your containers feel truly refreshed.

Lemon juice and sunlight to fade discolouration
Lemon juice and sunlight are effective tools to fade discolouration on plastic containers. The process is straightforward and makes use of the acid in the lemon juice and the sun's UV rays.
Firstly, cut a lemon in half and rub it along the discoloured areas of the container. Squeeze the remaining lemon juice from the lemon half into the container. Next, place the container in a sunny location for a day or two. The sun's UV rays will work with the lemon juice to fade the stain and kill bacteria. After this, wash the container with hot soapy water to remove any remaining stains and then air dry.
This method can also be done with the addition of salt. Squeeze lemon juice directly onto the stain and pour salt over the juice. Then, rub the lemon juice and salt together so that the salt's abrasion helps work the lemon juice into the stain. After this, place the container in the sun for nine hours.
Lemon juice is a natural cleaner that can be used to remove stains from plastic. It is best to use fresh lemons for their acidic power.

Vinegar to clean without causing damage
Stained plastic containers are unsightly and off-putting, especially when you're about to eat from them. While these stains are not an indication of anything unsafe or unclean, they can be difficult to remove.
A common cause of staining in plastic containers is carotenoids, which are red, yellow, and orange pigments found in tomatoes, turmeric, and peppers. When cooked with oils, these pigments bond with porous plastics and form stubborn stains.
One effective method to remove stains from plastic containers is to use vinegar, specifically distilled white vinegar. While it may seem counterintuitive to use an acid to remove stains, research has indicated that carotenoids become more transparent when exposed to acids. Here's how you can use vinegar to clean your stained plastic containers without causing damage:
Vinegar to the Rescue
- Soak the stained container in distilled white vinegar: Fill the container with 5% distilled white vinegar and let it soak for 12 hours. The vinegar will help remove the stains without causing any damage to the plastic.
- Observe and repeat if necessary: After 12 hours, check the container for any remaining stains. If there are still some stains, repeat the process or try using a dishwasher.
- Use cleaning vinegar for tough stains: If there are still some stubborn stains, try using a stronger concentration of vinegar, such as 30% cleaning vinegar. Soak the container in the cleaning vinegar to remove any remaining stain remnants.
- Wash and rinse: After using vinegar, always wash the container with dish soap and warm water to remove any trace of the vinegar scent. Rinse the container thoroughly and allow it to air dry.
- Be cautious with sensitive surfaces: Avoid using undiluted vinegar on sensitive surfaces like electronic screens, natural stone countertops, and certain appliances like irons and dishwashers. Undiluted vinegar can damage anti-glare properties on screens and etch or dull natural stone surfaces.
- Dilute vinegar if needed: When cleaning sensitive surfaces, dilute vinegar with water. For example, use equal parts water and vinegar for cleaning computer screens, and consult your dishwasher's manual for safe cleaning solutions.
By following these steps, you can effectively use vinegar to clean your stained plastic containers without causing any damage. Just remember to adjust the vinegar concentration and cleaning method according to the surface you're working with.
