Plastic food containers are lightweight, affordable, and convenient, but they can be a pain to clean. Food stains, particularly those from tomato sauce, curries, or buffalo sauce, can be extremely stubborn and refuse to come off with hot water and dish soap. However, a simple and effective solution exists in the form of vinegar. By soaking or filling the stained container with vinegar for a few hours, you can break down the stains and neutralize odours. While vinegar may not work on very old food stains, it is a powerful cleaning agent that can be enhanced with the addition of hot water or baking soda.

Dilute vinegar with water for lighter stains
Vinegar is an effective cleaning agent for stained plastic containers. It is particularly useful for tough stains, but for lighter stains, it should be diluted with water so that the plastic doesn't wear down. The process is simple: first, wipe the container with a clean paper towel or sponge to remove any leftover grease. Next, make a solution of water and vinegar, using 1 tablespoon of vinegar per 1 cup of water. Pour the solution into the container and let it sit for 1 to 2 hours. Finally, wipe the container clean, rinse, and dry.
The reason vinegar is so effective at removing stains is that the majority of food stains are acidic, and acids like vinegar can dissolve them. This is because "like dissolves like," meaning similar substances can dissolve each other. In addition to removing stains, vinegar can also help to deodorize smelly plastic containers and remove grease.
It is important to note that vinegar may not work on very old food stains. If you're looking for a stronger solution, try letting the vinegar soak for longer or adding a bit of hot water. You can also use the vinegar to make a baking soda paste, which can be used to scrub the plastic container.
Some people prefer to use other methods to clean their plastic containers, such as soaking them in bleach or using baking soda and lemon juice. However, vinegar is a natural, safe, and effective alternative that can be used to remove even tough stains from plastic containers.

Soak containers in vinegar for 1-2 hours
So, you want to clean your plastic food containers with vinegar? It's a great, natural way to remove stains and odours. Here is a step-by-step guide to the process:
First, wipe the container with a clean paper towel or sponge. This will help remove any leftover grease or food remnants. If there is caked-on food, you can use hot water to loosen it before you begin the vinegar soak.
Next, fill the container with vinegar. You can use white vinegar, or a mixture of vinegar and water. The amount of vinegar will depend on the size of your container and the severity of the stain. If the stain is on the bottom of the container, fill it with around an inch or two of vinegar. If the stain reaches up the sides, fill it to the top. Make sure the vinegar covers the stain. You can also add a squeeze of lemon juice to brighten dull plastic and leave it smelling fresh.
Now, place the lid on the container and let it sit for 1-2 hours. The vinegar will work its magic, breaking down discolouration and neutralising odours. For heavier stains, you can leave it for longer.
After the soak, pour out the vinegar and scrub the container vigorously with a sponge or stiff-bristled brush. Add a few drops of liquid dish detergent and some warm water, and scrub again. Rinse and dry the container, and your plastic food container should be stain-free and sparkling clean!
This method is a great, natural way to remove stains without the need for harsh chemicals. It may not work on very old food stains, but it is an effective way to tackle fresh marks.
