Steve, I viewed not just the picture you referenced but all of the pictures at that site and was unable to detect ANY corrosion of any kind. What you are seeing are scratch marks in the anodized plating due to having the Rb removed from heavily plated circuit board that is used as a heat sink for the Rb. At one end of the physic package is a circular shaped housing which has some rosin left on it, a thermistor or two attached and some kind of bonding material used for mounting the heating transistors that has changed color because that part is heated when it is running; that is not corrosion. The screws attaching that item to the rest of the physic package have fiberous material for a mounting washer to buffer vibration or are used as insulators; that is not corrosion. The screws that are holding down the circuit board press down on a gold plated circular area used for grounding besides being used for a mounting point; that is not corrosion.
I think you need to reboot "your" internal operating system and then do a serious update on your help files.
