Never used it myself. I either use proper degreaser in a bath (like the ones in car garages) or if it's not that bad, I'll use a bit of Muc-Off or some other soapy solution.

Get a rag, soak it in that kind of stuff and then wash all the crap off with water. Then, when it's dry, apply some decent lube so that the whole lot doesn't cease over the winter.
