A nonwoven wiper comprising a composite web (12) made of a number of interbonded layers (102-116) of meltblown thermoplastic fibers. The outer layers (102,104; 114, 116) have average pore sizes greater than 20 mu m and preferably greater than 40 mu m for rapid pick up of liquid. The internal layers (106-112) have average pore sizes between 10-20 mu m for liquid holding capacity.
