Here's a breakdown:
* Natural Sponges: Natural sponges, derived from marine animals, were used for cleaning and bathing in ancient civilizations. They were readily available and effective.
* Cellulose Sponges: The development of cellulose sponges, made from wood pulp, emerged in the early 20th century. This involved processes like pulping and forming the cellulose into a sponge-like structure.
* Synthetic Sponges: Modern synthetic sponges, often made from polyurethane or melamine foam, are a relatively recent invention. They offer durability, flexibility, and various cleaning properties.
While specific inventors of specific sponge types might be hard to pinpoint, it's important to recognize that the evolution of cleaning sponges has been a gradual process driven by human ingenuity and the need for effective cleaning solutions.
