Logic board repair with cleaning and increase conductivity?

Is there any success in cleaning logic boards using isotropic alcohol? I have Eletric 2-26 that increases electric conductivity of weak/damaged wires and ports. Has anyone used this on the ports to get rid of touch screen and backlight issues? For water damage with corrision near the problematic area, perhaps cleaning things up and applying extra conductivity to the ports might compensate for boards that still power on?

What gets me is how a lot of water damaged iPod touches still power on, but just have one feature go bad lol.

So far, I've significantly reduced a backlight issue about 80% by cleaning up the corrision and drying it in rice, but the problem is still there. It used to not come on at all, now it comes on about a good 80% of the time and goes off for a few mins, then back on.

Thanks

I have 7 iPods with backlight or touchscreen issues that could turn into a gold mine if I can fix them all. So far I've only fixed 3 of them ;-P
