Food stains are marks left on surfaces or fabrics when food or beverages spill or come into contact with them. Common sources of food stains include items like tomato sauce, coffee, and red wine. These stains can be challenging to remove, especially if they are not treated promptly. The process of removing food stains often involves using specific cleaning agents or techniques tailored to the type of stain. For example, bleach may be effective for white fabrics, while vinegar or baking soda can help lift stains from various surfaces. Proper care and quick action can minimize damage and restore cleanliness.
