Designed for deep cleaning, the heavy-duty scrub sponges also have four times the scrubbing power of the next leading brand, allowing everyone to easily remove tough, baked-on/dried-on messes without the need for presoaking dishes. They are recommended for pots and pans, BBQ grill, cast iron, oven racks and dishes.
