Not always, but usually.

The fluid dries and is rather hard to see; you have to look for an
area of the PCB that appears to have a different sheen or appears to
have a coating of some sort.

   Damage may be hidden underneath a capacitor- look carefully for
black areas and for solder pads to appear corroded.

I'd love to know how he tested them in-circuit.
