When I use Cramolin (I still have a bit of the concentrate) or DeOxIt
on contacts, I follow it with a final cleaning using isopropyl or
denatured alcohol (or acetone if I'm feeling really thorough), to
remove the remains of the anti-oxidant.

I use 409 cleaner, which has a pH of about 11, or ammonia window
cleaner, both of which should neutralize the acid. Acetone will make
a mess of anything plastic and really is overkill.

True - it's for metals-only applications.

For open frame
relays, I sometime use electroless silver to replate the contacts.

Is that Cool-Amp (powder), or some form of liquid electroless silver?

I've made up (and use) a homebrew substitute for Cool-Amp - silver
chloride and salt, finely ground, and then rubbed in firmly. Makes a
nice, solderable surface for DIY PC boards.
