If tomato sauces are turning your plastic containers red, try this simple method of removing tomato stains.
The secret to removing tomato stains (from plastic anyway) is contained in one of these.
When I store tomato-based sauces in plastic refrigerator dishes, or microwave such foods as chili and spaghetti sauce in plastic bowls, I usually end up with stains in the containers. I didn't want that, so I found a way of removing tomato stains: put a few tablespoons of lemon juice in each dish, fill it with water, and let it soak. In a short time, the stains are gone.
