Oh- I feel your pain. I have been riding for almost 20 years, and I still (rarely) find a better way to do something.
Here is part of what I posted to an "interesting articles" post about guns, no less-
I am a mountain bike fanatic. I can't imagine anything more harsh on delicate mechanisms than biking for hours in rain and mud. Good mechanisms are not overly sensitive to dirt and are well sealed/shielded, but not in a way that traps dirt or moisture.
I have tried everything from light oils like tri-flow, to heavy oils, greases, greases thinned with oil, hot-dip wax lubes, etc. I finally stumbled across Amsoil metal protect sprays (regular and HD), which are easily some of Amsoil's best products. The "regular" goes on oily but dries to a light film. It's supposedly great for guns. The HD is really amazing. It dries into a heavy, lubricating wax-like coating that is completely water proof and dirt proof. It's fantastic.
I realized I had only been destroying my parts with oil and grease all these years. Oil and grease is designed to be used in SEALED, CLEAN mechanisms. NOT exposed to moisture, corrosive contaminants, dirt, etc. Grease and oil is sticky and will actually ATTRACT these contaminants and carry it into mechanisms. Grease or oil is not appropriate for exposure to harsh or dirty environments. It can be worse than nothing.
Since trying these new dry lubes (there are some other brands as well), I do not use ANY oil or grease on exposed mechanisms, cables or chains on my bikes, tools, under-hood, etc. unless it is behind a good seal. Metal Protect HD goes on, stays on, doesn't get all over you and your clothes, doesn't suck up dirt, is totally waterproof, seals mechanisms, and when covered with mud, can just be washed off with water to continue performing.
There are several new dry-lube products out there now. I think Amsoil is the best, and Metal Protect HD is also by far the cheapest considering the huge can. Many companies have made chain dressings for years that work well in clean environments, but are still tacky enough to attract dirt. When exposed to dirt, they must either decompose and fall away, or absorb the dirt. I used to use chain-wax. It is great. Amsoil HD-MP is just as good and much simpler to use. To clean things off I use citra-solv degreaser in a clip-on chain cleaner.
That said, fenders are the best protection for your parts- especially a deep, low front fender with a mud flap. It's a lot of work to make them removable and sturdy, but well worth it. It seems foolish to me now to ride in real muck or rain without fenders because you and your bike stay so much cleaner there is no comparison. My shoes even stay dry! Just be sure to mount fender stays up high on the fork with straps. If you use the low factory mounts at the drop-outs, the fender can jam hard against the tire in the even of contact or debris in the spokes or tire - a real saftey issue.
As for chains, I used to swear by Sachs. Shimano hyper-glides sucked bad. Now it has all changed. Sachs/SRAM is terrible, and Shimano is very good. Oh well.
You can check your chain with a tape measure. The links are exactly 1/2 inch. If you can see a difference (measuring from your cassette to your crank) it's time to replace.
Now ask me about making derailer covers out of plasti-dip...
