Camden, The practice of using a water wash in between developer and first
clearing bath got a little muddy during the mid to late 90's as far as I can
tell. I think that for some it can really be an issue based on the contents
and pH of your water. 

If you stay on the acid side that is a safer way to go. If you do use a
water wash, I found it BEST to use distilled water. Your first clearing bath
after an acid wash can also be more acid by using Di sodium EDTA instead of
the Tetra sodium; pH of 7ish as opposed to 10ish for tetra. Then use the
tetra sodium for your third bath.
