I am curious what people do to care for their bike's drive train (chain, crank, cassette, bottom bearing, rear hub, front and back derailleurs) for the different type of riding they do. Aside from adjustments, how do you care for your bike to clean it, lube it, etc...?

I notice that as soon as I take my bike through a ravine especially these days, there is so much tall grass, weeds, and crud that within a few minutes I have twigs and leafs sticking out of the cassette and crank, the chain looks and sounds like it is covered in greasy sand, and the bike starts to make all soft of annoying grinding and clicking noises. I find layers of the chain grease get caked onto the rear derailleur cogs and start causing the chain links to stick. Today I plowed out through a meadow and came out with a floral arrangement sticking out of the shifter on the handlebar.

Is it normal to have to clean the bike after every such ride? If I stick to paved roads, I obviously have none of that, but I really like the rougher terrains. I have been cleaning the drive train with a wire brush and carburetor cleaner to break down the greasy grime on the gears, derailleur springs and cogs, chain. And re-lubricating the whole bunch with teflon dry grease.

For the hub and BB I have been putting on a little bit of high speed high temperature motor bearing grease on the outside but it seems near futile as all it just sits on the surface and clearly does not run into the actual bearing. My worry is the carb cleaner eating away on the bearing grease originally in there.
