PCM corossion. How can I clean this up? Pics inside.
So I've been having an issue with my car and I figured I would pull the PCM out and clean it up. Good thing I did. I have pictures of what I found. How can I clean up these pins? Anyone know or have an idea?

Have fun trying that
First you'll have an issue finding a pipe cleaning brush small enough and next you have trouble doing it without bending the pins
You can find little contact cleaning brush set, but I've never been impressed with their performance and they cost around $40 for a set, I don't feel they're good for anything other then cleaning the contacts on trailer connectors
To the OP, did you pull the plactic retainers from the connectors and see how bad that side is?

That's not that bad. How's the connector's look?
I would try some electrical contact cleaner and work the plug's in and out. Then you can blow out both with some compressed air after you loosen the corrosion up.

Be lucky you found it now. I had a pin rotted right off. Torque conveter lock up was getting really erratic which is what lead me there. Ended up openning the case and pushing enough through to work again.
Just use some electrical contact cleaner spray and compressed air. Then use some dielectric grease to prevent further corrosion. Check to make sure the female terminals are cleaned too.

The female side of the connector looks okay. It did have water in it and some dirt but it was fairly easy to blow out with some canned air I had for my keyboard. Where can I get some electrical contact cleaner and dielectric grease? I know what the dielectric grease looks like but what does the contact cleaner look like and where do I need to go get it?

Dielectric grease is an insulator, generally not a good idea to use it on things that are supposed to conduct current. It would be pretty hard to use it without getting any on the contacts. Anyway, as I recall there's a gasket on the connector, maybe it can be replaced? Just need to keep moisture out.

Seals look good but I'm not sure if they leak. The guy I bought the car from (the original owner) said he always washed the engine off when he cleaned the car. So I'm guessing over the years it has just accumulated water. That and the fact that I live in Washington and it never stops raining here. It's always wet. It cleaned up really well though. I used a small pick to get around the outside of the terminals and the cleaner. It looks nice but I'm going to touch it up again later tonight. I'll post up some pictures when I'm done for a before and after for anyone else who finds themselves in the same positon with a similar problem.
