I saw my neighbors neglected drivetrain a couple weeks ago and his chain was "caked" with road grime and was pretty sticky. He ended up getting a new chain and had some work done on other parts. I'd like to avoid that and keep my drivetrain in good shape. I was at the bike shop today and got some Finish Line Speed Bike Degreaser and White Lightning lube.

I have about 350 miles on my bike, with close to half of those miles on a gravel trail. So there is a bit of dirt and grime build up already. The chain should be pretty easy to clean, but what about the gears and chain rings? Should I just blast away at them with the degreaser?

What would be a good interval for degreasing, or just lube every so many miles in between a degreasing session?
