Try using a hot DI rinse with a ph of no less than 4 for a final rinse,
cut the last h2so4 dip down to 3% and monitor the turnovers in the bath
you should be able to get a very nice bright pink surface where you
don't need any surface treatment before subsequent processing.

PCB-boards after plating with electroless copper. Does anybody brush the
