At the present time, hypochlorite solutions are widely used in home laundering for bleaching fabrics such as diapers. Some physicians, however, have the impression that bleaching of diapers is contraindicated, feeling that bleached diapers are irritating to the skin of infants.6 To our knowledge, a controlled study to determine the effect of bleaching on the bacterial contamination of home-laundered diapers or on the infant's skin has
