Also take the plate off A4000 boards to avoid surface rust that covers the Mouse / Joystick ports. It took about 9 hours to dry the board, I had to go out half way through so I stopped the oven and noticed some water left near the central AMP connectors for the bridge board so I dried it again when I got back. Very minor surface rust too on serial / parallel outer metalwork.
I will up the temperature on Frankenoven as mentioned before and make sure that the boards are dried in one go over I think 2 hours, if 50 degrees still isn't enough I will go to 60 degrees and no more, 120 degrees C is the temperature set of reflow ovens in their cool down stage but plastic on the Amiga board may be susceptible to higher temperatures, also some of the chip labels.
Will get a horse hair brush and brush it, some residue from areas where capacitors leaked, anyone know what the chemical process is and what the residue could be, flaky, very slightly greenish / off white.
