I used
ProGold Lubricant's PG-2000 to clean my Micra a couple months ago.
It's different than the ProGold cleaner used on electrical contacts... it's a chain cleaner that's much better for metal-to-metal cleaning and lubricating than WD-40. I use it for my bike chain (Migs - you should try this stuff - it's regarded as one of the better chain lubes out there). It comes in "ProLink" chain lube squeeze bottles, or the PG2000 spray can - same stuff (I checked with ProGold - the ProLink is
barely thicker, to the point of not being able to tell), just two different ways of applying it.
It went on the joints of my Micra, which I thought was so mucked up and stiff that it wouldn't be salvageable, and it brought it right back to life!
