Scourers and sponges are cleaning tools used for scrubbing and wiping surfaces. Sponges are typically made of synthetic or natural materials and are used for general cleaning tasks, including washing dishes and wiping countertops. Scourers, often made from abrasive materials like steel wool or plastic mesh, are used for tougher cleaning tasks to remove stubborn dirt and grime. Both tools are essential for maintaining cleanliness in kitchens and bathrooms.
