Detergents are substances used to remove dirt and stains from surfaces, fabrics, and other materials. They work by breaking down oils and grease, allowing them to be washed away with water. Commonly found in households, detergents come in various forms, including powders, liquids, and pods, catering to different cleaning needs. In addition to laundry applications, detergents are also used in dishwashing and surface cleaning. They often contain surfactants, which help to lower the surface tension of water, making it easier for the liquid to penetrate and lift away grime. Understanding the right type of detergent for specific tasks can enhance cleaning efficiency.
