I like the Finish Line Ceramic Pro lube better than the Wet Lube. I get noticeably better chain life with it and the chain stays a little cleaner. It's a wet lube which I now use winter and summer.

I use one of those chain cleaner gadgets when my chain gets really dirty. I use paint thinner in it. The trick to them is to keep changing the fluid until when you roll the chain between your fingers, you don't hear that gritty sound any more. Then dry the chain with a heat gun or hair dryer while you move it past the gun. When the chain is quite warm, it's usually also dry. Then apply the lube. Just put it on while rolling the chain by, until you have plenty on there. Then heat it again with the gun to make sure it's in the rollers and, as other have said, wipe really well. Also wipe the cassette cog, jockey wheels, and chainrings, then the chain again. This whole process doesn't have to take very long. A couple hundred miles after cleaning, reapply the lube and rewipe. Then you should be good for quite a while. You should be able to tell if your chain needs lube by the sound. Chain should be silent or almost.

If you're on the road, just wipe, lube, wipe.
