Why does tomato sauce stain plastic? The culprit for those stains is a bright red pigment in tomatoes called lycopene. This molecule is ‘hydrophobic’ (it repels water), and so are your plastic containers. Hydrophobic molecules come together in order to minimise their contact with water, so the pigment clings to the containers.
How do you get red stains out of plastic containers? Simply combine 1 teaspoon of water, 2 tablespoons of baking soda and 1/4 teaspoon of dish soap in the red-stained container. Use an old toothbrush or other type of gentle scrubbing tool to work the paste into the plastic. Then, allow it to sit for about 15 minutes, scrub again and rinse with clear water.
