I grew up using plastic food containers(the Tupperware age), and I learned that they are tough, super convenient, and saved my mom a ton of money.

Plastic food containers aren’t just for storing leftovers either. Put them in your car, use them on the patio, or bring them to work with you! Their adaptability makes them extremely valuable. Cleaning them, on the other hand, can be a chore. Especially when they’re so greasy that mere dish soap won’t do the trick.

Enter baking soda. Using just a little bit of baking soda when washing your plastic food container can easily clean and degrease. Even old stubborn water stains are no match.

In this article, I’ll show you how to clean plastic food containers with baking soda.

How Do You Restore Discolored Plastic Food Containers?

Are your old plastic food containers starting to look a little yellow? Try scrubbing it with baking soda paste.

Using baking soda paste is one of the most effective techniques to erase that annoying yellow color from plastic. To do this, make a paste with the baking soda and apply it to the yellowed plastic.

In a cup, combine the water and baking soda until it makes a paste(mix equal parts baking soda and water), then apply it to the plastic container and let it sit for several hours. Remove the paste with a sponge or towel, then thoroughly rinse the food container.
