The more sanitary, dual-sided Brillo Estracell Heavy Duty Scrub Sponge easily removes burnt-on foods. Its made with unique fibers that dry faster and rinse 10 x faster than other sponges, too. We made a different sponge for all your surfaces, so you can clean up without spreading bacteria around. This, plus the fact that bacteria won't grow on our Estracell sponges, makes them more sanitary.
