Even though it's February, I'm still trying to figure this out. How do you clean your bike during the winter? I live in an apartment with very young children, so I don't have a garage and my space is limited where I can work with chemicals, without risking my children getting into them. I also still have about 7" of snow outside (where I usually clean my bike).

So what do I do to make sure my bike (especially the drivetrain) is properly cleaned?
