I've become much more hesitant to do the full on degreasing down to bare metal on chains after reading on the interwebs that getting rid of all of the original lubricant isn't a good idea (and iirc manufacturer's instruction caution against full degreasing). I'll spray with WD-40 while the chain is on the bike, run it through a rag to get off the worst of the gunk, and re-lube with whatever product I have on hand.
