If I know I won't be riding for a couple of weeks, I'll clean my bike. I try to get on the bike at least a couple of times a week though to practice some technique for at least an hour or two each time. I usually finish up at dark and it's getting really cold. I was raised a "clean it before you park it" guy, but that doesn't seem practical in my current situation. Do you always clean your bike after a ride? How long do you go between cleanings if you ride a lot (excluding bad mud). And if you aren't washing the bike between every ride, is there anything that you definitely make sure gets done between each ride?
