Laptop Keyboard

After a spill necessitated replacing the keyboard on my Satellite A135, about 1/2 of the keys, mainly on the left side of the keyboard, don't work. I can't seem to press the plastic ribbon cable of the new one into the connector far enough for it to engage all the pins. I tried reattaching the old keyboard, but can't press that cable in far enough either. There seems to be white mineralization on some pins in the connector. It's a very thin space, and barely accessible. How can I safely clean it off so the cable fits properly and makes contact with all the pins?

I would use some alcohol. Depending on the size and your ability to solder, I would see about desoldering the whole connector and cleaning it so you don't screw anything else up.
