Before each ride I squirt some pro-lube on my chain, spin it a few times, and then wipe off the excess. Occasionally I use a citrus degreaser to clean the chain. Now, I've heard you shouldn't degrease your chain because it will actually break down the new lube you put on it. That makes sense to me but cleaning your chain seems to make more sense. Also, Pro-lube claims that it's lubricant "pushes out" grit and grime while lubing. Is that even possible?

What are your thoughts on lubing? degreasing? Thanks!
