	As a side note.  Th red erasers normally leave a corrosive
residue behind.  If using them, get the softer, non abrasive type, and
*flush* the connector with contact cleaner.

	The white is a better idea, though you should always flush the
connector.

	What I have the techs here do is damp a cotton twill cloth
(the type you can be in a package for clean room apps, no lint) with
contact cleaner, and lightly rub the surface.

	Clean the surface very well, but does not damage it.

	We get TexWipe TX306, 300 count 6x6in cotton twill wipes.
Totally lint free, does not shred under use.  Used here for all
contact cleaning.
