The Optimal Baby Bath Sponge is an ultra-gentle, dermatologically safe cleansing accessory created specifically for newborns, infants, and toddlers. A traditional hand-held polyurethane cleansing sponge. It features micro-porous texture loops that maximize soap lather with minimal baby wash. Unique to this model, it is hot-water resistant and washing machine safe, preventing the bacterial growth common in standard bathroom loofahs.
