Over the weekend I rode a 600km brevet, almost all in light to medium heavy rain. It included twenty or so miles of gravel/dirt roads. At times my shoe covers were coated with a layer of mud and grit, later cleared off by rain.
Due to a last minute issue, i had a rear fender only, so you can imagine how much crap was flung onto the drivetrain.

Frame is steel, bearings are cartridge. Chain is newish, wheels are new, BB is pretty new.

I wonder what level of cleaning is recommended.
The next day, I hosed the bike down, washing away as much grit as possible from the drivetrain, disc calipers, derailleurs, and other surfaces. I then cleaned the exposed surfaces with a rag and Simple Green, rinsed, and wiped down what I could. Finally i applied chain lube, and sprayed WD-40 in all pivot points.

Brake pads are shot, so those will be replaced.

I wonder if i should go to the next level, disassembling jockey pulleys, replacing cables, even inspecting and potentially replacing bearings.
