Is there a way to remove corrosion off electronic components?

Yeah just warning people that if evaporust is safe to use but alternatives may not be as safe.
Interesting.
BradC:
Just be aware that Chloride ions are tenacious little buggers and like to stick around. Your post-etch cleaning process needs to be meticulous or you risk ongoing corrosion down the track (both figuratively and literally).

It looks a bit like the Uher "reel to reel" tape recorder I once had, that had been through a cyclone.

I would also be worried about etchant seeping into the case along the pins.

I would simply use a fiberglass brush to remove the corrosion mechanically.

YES!

If they still work after that bath in etching solution, just how long will that continue to be true. Most IC packages are not hermetically sealed. Gas and liquids can enter and, once inside, would be very difficult to remove.

Mechanical cleaning would be best. Followed quickly by a tinning to prevent further corrosion.
