The data sheet for Ilford low volume chemicals and Delta 100 Professional make no mention of prewashing. Nor does EK's data sheets on the T-Max family, downloaded from EK's web site. Agfa's tech data for b&W chemicals (Tech data P-16-C) makes no mention of prewashing. Ilford's tech info. for PAN F Plus makes no mention of prewashing. I can't answer for other knowledgable or authorative sources. I do it, but I don't remember when or why I started. Part of the folk lore of photography?
