Commercial sponges are natural or synthetic materials used for cleaning and absorbing liquids. They are often made from the fibrous skeletons of marine organisms, particularly sea sponges, which are harvested for their soft and porous structure. These sponges are popular in households and industries for their ability to hold water and soap, making them effective for various cleaning tasks. In addition to natural sponges, there are also synthetic options made from materials like polyurethane or cellulose. These sponges are designed for specific uses, such as dishwashing, bathing, or industrial cleaning. Both types of sponges are valued for their durability and versatility in everyday applications.
