I finally got to starting the clutch replacement on Gertie ('85, 1.9)

When I got the axles removed fromt he trans I discovered that the passenger
side CV seems to have some pretty old grease in it. ANy suggestions on the
best way to clean that up and prepare it for adding some fresh grease -
Without disassembling it. I mean I can figure it out on the basic side but
is there anything I shouldn't do - or anything specific I should do?

The Driver side looked fine and has some nice clean grease in it.

Advice as always is appreciated.
Thanks,

Jeff
