DeOxit on old mac PCBs

I finally succeeded in getting my Macintosh SE opened up(after finding a long enough screwdriver) and unfortunately found a lot of verdigris and other corrosion on parts of the logic board.

I can't get a hard drive to work(I tried a couple of different, known good 50 pin SCSI drives) and I suspect it's due to corrosion around the SCSI socket on the logic board.

I'm wondering if anyone has ever tried DeOxit to deal with this type of situation? As per their website, this is what the "D" series sprays were made to do, but I don't want to spend $15 on something that won't work, or even worse could possibly cause damage. Radio Shack here in town has D5S-6 in stock, so I can get some today and am anxious to try it if it will work. As I said, though, I wanted to ask before trying.

Thanks in advance for any help.

My curiosity got the better of me(if nothing else I figured the DeOxit would help me on my Zenith Trans-Oceanic radio).

In any case, I gave the SCSI socket on the logic board a squirt of it then connected/disconnected the cable several times as per the instructions.

I have System 7 installing at the moment. Unfortunately, the internal floppy is dead(I need to try and rebuild it) but in the mean time I have an external that's working great.(If anyone could point me toward an online guide to rebuilding the SuperDrive, I'd be most appreciative).
