The grease used in the CV joints has moly disulfide, which is a black 
powder that will stain anything. I wipe them out first with newspaper 
and then with an old rag. They don't have to be perfectly clean, just 
enough to get all the dirt out. You'll have to take them apart to do 
this, so make sure to have a Bentley with you if you hope to get them 
back together.

Any good grease with moly disulfide additive. These will always be 
black.

This is a fairly involved job, so I've stopped doing it at all unless 
the boots are torn. I generally end up doing it on cars right after I 
buy them, when the boots are torn. I've never had a CV joint actually 
fail on me.

This is so much work that I really don't recommend doing it at all, 
unless there is a problem in there. Those bearings are nicely sealed 
and any time I've taken these parts apart they've been fine, and the 
grease has been clean and plentyful. In my opinion, this is one place 
where you can save yourself a lot of pain without any significant 
downside.
