A cleaning sponge is a soft, absorbent tool used for scrubbing and wiping surfaces. Typically made from materials like foam or cellulose, sponges can hold water and cleaning solutions, making them effective for various cleaning tasks. They come in different shapes, sizes, and textures, allowing users to choose the right sponge for specific jobs, such as washing dishes or cleaning countertops. Many cleaning sponges are designed with one side for scrubbing and another for gentle wiping, catering to different cleaning needs. Some sponges are even infused with antibacterial agents to help reduce germs. Regularly replacing sponges is important for maintaining hygiene in the home, as they can harbor bacteria over time.
