Cloudy plastic containers are an eyesore, but there are several ways to make them clear again. The discolouration is usually caused by food residue, and the longer it sits, the harder it is to remove. Before attempting to clean the container, ensure that it is at room temperature and free of visible food particles. Then, you can try various methods, including using a vinegar solution, a sugar scrub, baking soda, or bleach. It is important to avoid using anything abrasive, as this can permanently damage the plastic.

What You'll Learn
Use vinegar and water
If your plastic containers are cloudy and filmy, it is most likely due to dust and grime, or plasticizer leaching out of the plastic itself. White vinegar can be used to clean cloudy plastic containers.
One method is to fill the sink with hot water and several cups of white vinegar. Separate the boxes into lids and bottoms and give them a soak. If the containers cannot be disassembled, dip a clean, lint-free cloth in vinegar and give them a vigorous wipe-down. Let them air out and dry completely.
To remove stains, wipe the container with a clean paper towel or sponge, even if it has already been washed. This will help remove any leftover grease in the container. Next, fill the container with enough white vinegar to cover the stain and let it sit for 12 hours. Repeat the process, this time using a dishwasher.
A solution of water and vinegar can also be used to clean stained containers. To make the solution, use one tablespoon of vinegar per one cup of water. Pour the solution into the container and let it sit for one to two hours. Wipe clean, rinse, and dry.
It is important to note that vinegar may not work on very old food stains. If the stains persist, try letting the vinegar soak for longer or adding a bit of hot water.

Try sugar and ice
If your plastic containers are looking a little cloudy, there are several methods you can try to get them clear again. One such method involves sugar and ice.
Firstly, cover the bottom of your plastic container with around 1/4 cup of sugar. Next, add a drizzle of dish soap, a few tablespoons of warm water, and five ice cubes. Let the ice melt, which should take around an hour. Once the ice has melted, dump out the contents and scrub the remaining sugar out of the container with a damp cloth. Finally, rinse the container with warm water.
This method can be effective for removing stains and can also be used to exfoliate your body. It is similar to a sugar scrub, which can be used to exfoliate the skin.
Other methods for cleaning stained plastic containers include using baking soda, hand sanitiser, bleach, vinegar, or lemon juice. It is important to note that vinegar may not be effective for removing stains, but it can help with removing odours and neutralising persistent smells. Additionally, sunlight is a great natural way to release odours and brighten the appearance of dull plastics.

Bleach and water
Bleach is a powerful disinfectant that can be used to clean plastic containers and remove stains and discolouration. However, it is toxic if ingested, so it is important to ensure that any bleach residue is thoroughly removed. When working with bleach, always wear rubber gloves and work in a well-ventilated space. If you experience any burning, eye-watering or dizziness, leave the room immediately.
To clean your plastic containers with bleach, start by mixing a solution of bleach and water. For a mild bleach solution, mix one tablespoon of chlorine bleach with one cup of hot water. If you are using powdered oxygen bleach, you can create a paste by mixing the powder with warm water and applying it directly to the stained area.
Once you have prepared your bleach solution, pour it into the plastic container, ensuring that all the stained areas are covered. Allow the solution to soak for at least 40-45 minutes. For powdered oxygen bleach, it is recommended to cover the container with plastic wrap to keep the paste moist and activated, and let it sit for at least four to eight hours.
After soaking, pour the bleach solution down the drain and thoroughly rinse the container with fresh, clean water to remove any bleach residue. Squeeze some dish soap into the container and use a soft sponge or washcloth to wash it until no oily residue or bleach scent remains. Rinse the container again with hot water and allow it to air dry completely before replacing the lid.
While bleach is an effective cleaning agent, it may react with plastic and can be toxic if ingested, so it is important to use it properly and thoroughly rinse the container after cleaning. There are also alternative cleaning methods available, such as using baking soda, vinegar, or hand sanitiser.

Baking soda and water
Once you have the desired consistency, spread the paste over the bottom and sides of the container, coating all the stained areas. Leave the paste to sit for at least 30 minutes, or even overnight for particularly stubborn stains. After this, use a damp cloth or sponge to wipe away the paste, gently scrubbing the bottom and sides of the container. Finally, rinse the container with hot water, and if desired, wash with soapy water.
For regular cleaning, simply add a good amount of baking soda to the empty and wet container, and use a gentle dish sponge to rub the baking soda into the plastic. Rinse well and repeat until the container is clean and odour-free.

Hand sanitiser
If you want to get your plastic containers clear again, one method that works is using hand sanitiser. Pour hand sanitiser over the stain, let it sit for about 45 minutes, then wipe clean and wash with soap and water. This method works because hand sanitiser contains alcohol, which is effective at removing stains.
You can also use hand sanitiser to refill smaller containers. If you have a larger bottle of hand sanitiser, you can use it to fill up smaller, travel-sized containers. This way, you can always have hand sanitiser with you on the go.
In addition to its practical uses, hand sanitiser can also be used for creative purposes. A concept called "beneficial reuse" involves using items that can't do their original job anymore for something else useful. For example, you could use old hand sanitiser bottles for a DIY project or give them to an artist to create a sculpture.
Finally, don't forget to dispose of your hand sanitiser bottles properly once you're finished with them. First, check if your bottle is recyclable by looking at the plastic type and your local recycling guidelines. If it's not recyclable, make sure the bottle is completely empty, screw the cap back on, and dispose of it in the trash. Capping it will prevent any remaining sanitiser from leaking out and harming the environment. Alternatively, look for special programs in your community that collect hazardous waste, as they will know how to dispose of it safely.
