Still can't see the pictures. However, in general it depends on how bad the components are, what they are, and how long the repair needs to function. Typically what you're up against with repairs like this (i.e. water damage) isn't the corrosion, but shorted/blown parts. For complex devices where you don't have a good schematic, this can be a headache to track down. I clean everything with 99% isopropyl alcohol and an esd safe brush. Depending on the circuit, I'll soak it for a while too. After that, you replace anything that looks to need replacing. You also might needs to expose new copper in spots for a place to solder. For some of the packages, if the leads (such as they are) are corroded away, you can try some point soldering to get a connection or a circuit trace pen for temporary signal lines. I also start with the programmable ic's first. If they're too far gone, you can't salvage the device.
