There were various fluxes about, some were sold as no-clean, meaning
once cold no (little) further corrosion. Inspect around and check the
condition and then decide whether cleaning is more damaging than leave
it on.

Hello all and thank you for adding me to the list.
I am in the process of restoring a NorthStar Horizon machine. The boards in
this machine have a significant amount of flux residue on them - it
certainly appears that this particular machine was constructed from a kit.
My question is about this flux - should I be removing it as part of my
cleanup, or should I leave it in place? I know that this isn't a
super-collectible machine or anything, but I've never come across this issue
in any other machine in my collection, and I was wondering what the general
consensus was. I'm perfectly aware of the corrosive nature of the flux and
how to remove it, however this flux has been there for 35+ years.
Thanks in advance for your thoughts.
