What materials are used to make cleaning sponges used for dishes?


    I've read that some of the original sponges were made from the skeletons of real sponges


    I D K! i don't think that they are made from real skeletons but maybe from a different substance


    y012f is correct that the original sponges were dead marine life but the new ones are synthetic, usually made of urethane foams or silicones. The composition varies somewhat depending upon the intended use; for example, a cosmetic sponge used for applying makeup would be different than those used for washing dishes.
