My mom taught me this trick to get red stains out of plastic containers with 0 effort. Here’s how it works

Red stains on plastic containers are a common issue, especially when dealing with tomato-based sauces and curry dishes. These substances are notorious for leaving behind a distinct red hue that seems to embed itself into the plastic. The primary culprit is the presence of lycopene in tomatoes and other natural pigments in spices, which are oil-soluble and cling to the plastic surface.

Plastic is porous by nature, which means it has tiny openings that can absorb colorants from foods. Even when we wash our containers thoroughly, these pigments can remain trapped in the microscopic pores, leaving behind a stain that seems impossible to eradicate. This is particularly true for older containers that have been through several cycles of heating and cooling, expanding the pores further and making them more susceptible to staining.

The magic ingredient my mom uses to banish red stains is none other than baking soda. This humble kitchen staple is known for its mild abrasiveness and natural whitening properties, making it ideal for lifting stains without damaging the surface of the plastic.
