The surprising reason people put a paper towel in greasy plastic containers

Plastic containers often develop stubborn grease stains from meals like marinara and curries. A simple paper towel and dish soap hack can effectively remove these unsightly marks. Warm water and soap are added to the container with a wadded paper towel. Shaking the container vigorously transfers the stains to the paper towel. This method revives stained containers, preventing them from being discarded.
