Plastic food containers are great ways to save leftovers or other foods. But over time, plastic can warp, stain, or remain greasy.
Many types of plastic containers are available, but many are designed for one-time use only. This includes takeout containers and dairy food cartons.
For reusable containers, wash them with hot soapy water or on the top rack of your dishwasher. Use the low- or no-heat drying cycle in the dishwasher.
To remove stains, let the empty container sit in the direct sun a few hours. Or, soak in a mild bleach solution of 2 teaspoons plain bleach per gallon of water.
For smelly plastic containers, soak them in a solution of 1 teaspoon baking soda per cup water or fill with undiluted vinegar.
