Default Re: Cleaning and repairing a Corroded computer board

As I've posted on the Forum previously, I tend to try citric acid solutions on stuff like this. Remember that this is sort of "lemon juice" in terms of its acidity but it is an excellent chelating agent, so really good at dissolving metal corrosion products. You can buy the powder cheaply in Wilko. Lots of info on Google.

Soaps can be caustic, can contain salt. Salt (chloride) is damn hard to remove (at trace levels) once it's on metal, so tends to re-start corrosion.
