    Best method to clean ECU terminals

    I'm getting a code 7 indicating a problem with the ECT sensor. I have already replaced the ECT sensor and checked wiring from the ECU to the sensor connector. Upon examining the ECU terminals I do see some slight corrosion on some of them. The terminals are a good bit recessed in the connector. I was just wondering what the best way to clean these terminals is? Wire brush?

    Use a stainless steel detail wire brush and then coat the teminals with silicone Di-electric grease.

    You could also try a clean like MG Chemicals Contact cleaner with Silicon, it works for electronics.
