Open cell polyurethane foam that does wipe dry and absorb as much liquid as a cellulose sponge plus so many other benefits, i.e., no odor, stay clean & brighter longer. Mfgers have been trying to develop a foam that would compete against cellulose for many years, Crest has finally created a foam sponge that works and it doesn't require felting or a secondary process. Right now the only U.S. mfger of cellulose is 3M which is also a competitor of all other consumer companies.
Foam Trial has been run twice and passes wipe dry and absorption property against cellulose.
Replace cellulose sponges with 3M cellulose that Clorox currently markets.
