Thanks Don & Kerik.

I'll definitely skip the rinse after development then.
I surmised that since the acid bath becomes so 'polluted' after running a
few prints through it without rinsing, that a rinse would extend the life of
the acid bath and thereby clearing would proceed more easily.  I did wonder
if the carry over was an important component of the process.
I'd rather have to replace the citric bath more frequently than have to
acidify the wash esp. since I tend to have multiple prints going through the
process at any given time.

Don't rinse after development. Put the print straight into the citric for
about 5minutes then move the print to a second citric bath for 5 minutes and
then rinse. Keep the citric fresh, it will cloud and exhaust quickly.  Rinse
fully after the 2nd citric bath. Follow with your sodium sulfide and EDTA.

See if that helps.

Eric, if your after-development water rinse is alkaline (above pH 7)  that
will make clearing difficult. Try going straight from the developer to the
citric acid and see if that helps.
