For everyday use, the S.O.S all surface scrubbing sponge is safe for most delicate bathroom and kitchen surfaces including marble, ceramic, tile and glass. It is teflon pan-friendly, too. Versatile enough for quick wipe-downs or the toughest clean-ups. Durable, absorbent and long-lasting, they are bigger and thicker than most ordinary sponges, and specially angled to access all those hard-to-reach nooks and crannies.
