Cleaning really small connections?

[tdatk]

My E46 has developed a case of the codes... After checking lots of stuff, the issue is coming from either bad harness or this bad connection at the DME. It looks like a green corrosion issue probly from road salt mist getting up there somehow. (pic)
It will run fine until I put the DME cover on the it gets wacky. How would you go about cleaning these terminals/connector?

Car's toast. I'll give you $2K for it. ;)

What? no love for the Bavarian brotha?
I used some very fine sandpaper with a small screwdriver for pressure on the pins. On the connector I used a acet torch tip cleaner and followed up with MAF cleaner and compressed air. Just ran it for 5 minutes without any codes....we'll see. This thing is like a HP brother to the fofo with its nitpicky issues.:D

maybe an ultrasonic cleaner with some non-aqueous solvent?

Took the car to my local shop that has BMW diagnostics this morning, looks like my connector cleaning did the job as it has no codes and all components checked out. I have read on lots of the BMW forums of cars with this same type of issue(s) none mentioned what I found......

I cleaned a receptical like that on my 1987 Merkur XR4Ti by dunking it into a mixture of a ~ one tbl spoon of baking soda in a cup of water. A few minutes was all it took to get rid of most of that green corrosion. Also works to clean corrosion off battery terminals. I does have a tendancy to fizz up and could potentially spatter though....

I was thinking of a Q tip and some kind of mild acidic solution to clean the pins followed by a ph buffer?

What would be a good non conductive paste or? for this connection? I have some spark plug stuff, would that work?

CRC makes a electrical contact cleaner...

Then I would just probably use some dielectric grease.

Thanks Eric, Exactly what I was looking for.
And thanks for the parts as well as putting up with the nOOb questions.:)

No problem. Lemme know when it comes time to do the brakes ;)

Anybody local carry that dielectric grease?

Maybe not CRC brand, but your local Advance Auto should have di-electric grease.

Something like this: http://shop.advanceautoparts.com/webapp/wcs/stores/servlet/product_Dielectric-Tune-Up-Grease-Permatex_12027861-P_N3451_T%7CGRP2035_____

Though I would prolly buy the smaller package. I still havent used up my tube (same as link above) in 5 years. And that is with me stepping on it by accident and losing about 1/4 of it!
