What You'll Learn
Soak in vinegar and hot water
Soaking cloudy plastic containers in vinegar and hot water is an effective way to restore their clarity. This method is particularly useful for removing mineral deposits, food residue, and grime, which can give plastic a cloudy or foggy appearance.
To start the cleaning process, fill your sink or a small bucket with equal parts distilled white vinegar and hot water. Ensure you use enough liquid to completely submerge the plastic items. If your containers have lids or compartments that can be separated, do so to allow for more thorough cleaning.
Before soaking, clean the plastic containers with mild liquid dish soap and hot water to remove any initial layers of dirt and grime. This step is especially important if there is visible debris or residue on the plastic.
Once your vinegar and hot water solution is ready, submerge the plastic items and let them soak. The recommended soaking time varies depending on the severity of the cloudiness. For lightly cloudy containers, 10 minutes to an hour of soaking may be sufficient. For more heavily fogged pieces, consider soaking them for several hours or even overnight.
After soaking, remove the plastic items from the solution and rinse them thoroughly with hot water. You may need to use a sponge or cloth to gently scrub away any remaining residue. Finally, dry the containers with a clean cloth and let them air dry completely.
By following these steps, you should be able to effectively clean cloudy plastic containers using vinegar and hot water. This method is a gentle and affordable way to restore the clarity and aesthetics of your plastic items.

Baking soda and lemon juice blend
To clean cloudy plastic containers, a blend of baking soda and lemon juice can be used. Baking soda is a gentle, natural ingredient that can effectively clean and deodorize cloudy plastic containers. Lemon juice is a good option for removing tough stains and killing bacteria.
Before using baking soda, wash the container with warm water and mild dish soap to remove any initial dirt. Then, sprinkle a layer of baking soda into the container and use a soft sponge or a toothbrush to work the baking soda around the container.
For a baking soda and lemon juice blend, combine the juice of one lemon with two tablespoons of baking soda. Fill the rest of the container with water. If you are cleaning a blender, blend the mixture on high for a few seconds, then turn it off and remove the blade.
Scrub the inside of the container with a non-abrasive sponge or microfiber cloth. Pour out the mixture once the cloudiness has cleared, then rinse and dry the container. You can also use a cut lemon to rub the baking soda into the surface of the plastic container. Rinse well and dry thoroughly before storing.

Avoid abrasive cleaning methods
To clean cloudy plastic containers, it is important to avoid abrasive cleaning methods. Abrasive cleaning methods can damage the surface of plastic containers and make them more susceptible to cloudiness and discolouration.
One way to avoid abrasiveness is to use non-scratch brushes. Tube cleaning brushes, twisted wire brushes, and toothbrush-style brushes are ideal for cleaning plastic containers without causing scratches. These brushes are designed to clean without damaging the surface of the plastic.
Another way to avoid abrasiveness is to use gentle cleaning solutions. Denture tablets, for example, are non-abrasive and effective at lifting stains from plastic containers. The fizzing action of denture tablets can dislodge stubborn stains without requiring any scrubbing. Similarly, a paste made from baking soda and water can be used to cut through stains and absorb odours without being too harsh on the plastic.
It is recommended to avoid using strong chemical cleaners on plastic containers, as these can be too abrasive and cause discolouration. Bleach, for instance, is highly potent and should only be used as a last resort for removing tough stains and odours. When using bleach, it is important to dilute it with water, wear protective gloves, and avoid prolonged exposure to the plastic.
Additionally, it is important to avoid using abrasive scrubbing tools such as steel wool or scouring pads. These can easily scratch the surface of the plastic, contributing to cloudiness and discolouration. Instead, opt for soft sponges or microfiber cloths that are less likely to cause scratches.

Use a magic eraser
To clean cloudy plastic containers with a magic eraser, start by wetting the eraser with warm water. Then, working in small sections, use gentle circular motions to scrub the surface of the container. Rinse each section with clean water as you go to prevent residue from drying. For stubborn areas, hold the eraser against the spot for 10-15 seconds before wiping. When you're done, wipe the container with a clean, dry microfiber cloth.
It's important to note that magic erasers are not suitable for all surfaces. While they are great for clearing cloudy shower doors and bathtubs, they may not be suitable for all types of plastic. In some cases, they may leave a cloudy line or even scratch the surface. Therefore, it is recommended to test the magic eraser on a small, hidden area first to ensure no discoloration or damage occurs.
Additionally, magic erasers should not be used on certain surfaces, such as mirrors, polished or shiny surfaces, stainless steel, non-stick coatings, or painted walls. Always read the safety labels and instructions before using any cleaning product.
Overall, magic erasers can be a useful tool for removing cloudiness and restoring the clarity of plastic containers, but they should be used with caution and according to the manufacturer's instructions.

Try a headlight restoration kit
If you're looking for a way to clean your cloudy plastic containers, a headlight restoration kit may be a good option. Headlight restoration kits are designed to remove cloudiness and yellowing from plastic headlight lenses, and they can also be effective on other plastic surfaces.
There are a few different headlight restoration kits available on the market, such as the Sylvania kit and the 3M kit. These kits typically include a surface prep spray or solution that helps to remove the old coating from the plastic. For example, the Sylvania kit includes a surface prep spray that melts away the old coating, while the 3M kit may require more manual labour with hand sanding.
To use a headlight restoration kit, you will usually need to apply the cleanser from the kit to the cloudy plastic container. The cleanser is abrasive, so it's important to be gentle and use circular motions to avoid damaging the plastic surface. You should see the cloudiness or yellowing disappear as you work your way around the container.
After cleansing, you can use a clean rag or towel to buff away any residual product. If there are any stubborn areas, you can spritz them with water and then polish them until they are dry. It is important to seal the container after cleaning to prevent cloudiness from returning.
In addition to headlight restoration kits, there are also specific plastic headlight restoration kits designed for cloudy and yellowing headlamps, such as the PROSTAFF kit from Japan. These kits are quick and easy to use and can provide long-lasting results.
