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

To use baking soda, simply sprinkle a generous amount directly onto the stained areas of the container. There’s no need to measure precisely, but you’ll want enough to cover the stained spots thoroughly. The next step involves a bit of patience, which we’ll discuss further in the following sections.

Baking soda works on red stains because of its mild abrasive quality and alkaline nature. The abrasiveness helps to gently scrub away the surface layer of the stain without scratching the plastic, while the alkalinity of baking soda neutralizes the acids in tomato-based sauces, making the stains easier to lift.

Moreover, when mixed with a small amount of water, baking soda forms a paste that can reach into the pores of the plastic, effectively breaking down the pigments and pulling them away. This dual action of physical abrasion and chemical reaction is what makes this method so effective against stubborn tomato and curry stains.
