During this time, you can go about your day without worrying about your containers. The extended duration allows the baking soda to work its magic, ensuring that even the most persistent stains are lifted by the time you rinse the container.
6. The Science Behind Stain-Grabbing Oils and Sauces
The reason why oils and sauces stain plastic so effectively is due to their chemical composition. Many oils and sauces contain lipids and pigment molecules that are hydrophobic, meaning they repel water but bond well with other non-water-soluble materials, like the polymers in plastic.
When these substances come into contact with the plastic, they seep into the material’s pores and stick, making them difficult to remove with water alone. Baking soda, with its unique properties, interacts with these oils and pigments differently, breaking the bonds and allowing them to be washed away.
