What I would suggest (ROHS or not) would be to take an old (ie, not used for anything other than electronics) sponge (or rag) and some powdered cleanser (eg: Ajax) and water, and give the boards a little scrub to brighten up the copper and remove any tarnish/oxidization.
Merry Christmas too all.

These parts and PCB's are a good five years old, so I'm sure everything
is pre ROHS, but wanted to know if I need to do any prep work on the
parts leads or boards.
Any suggestions or just fire up the iron and let the flux do it's job?
