Board erasers, also known as chalkboard erasers or whiteboard erasers, are tools used to clean or erase markings from chalkboards, whiteboards, and other similar surfaces. These erasers are typically made of felt or foam material that can easily trap dust, dirt, and ink residues. Board erasers come in various sizes, shapes, and styles. Some have handles for easy gripping, while others are handheld or simply small enough to fit in a pocket. It's important to clean board erasers regularly to prevent the spread of germs and to maintain their effectiveness. Board erasers are an essential accessory for classrooms, offices, and other settings that utilize chalkboards and whiteboards.
