Flux removal question

[Harry Bissell]

You seem to be right on target. I would avoid flux cleaner on
1) Polystyrene caps
2) Pots and Switches (it will remove lubricants etc...)
3) Jacks  (could leave a residue...)

I washed my PCB before installing these components.

Flux leakage can be a problem around high impedance areas like the VCOs,
S/H etc.  I usually try to scratch the flux away with an x-acto knife (gets brittle
after about a day, flakes off easy) then clean with a swab.

Your caps might be OK and they might be toast. Can't tell if they are damaged
until you fire it up. I'd try first...they might be fine.
