Some of the old cycling crumudgeon's like me use a hot-melt paraffin wax for chain lubrication... doesn't cause the drive train components to collect grime and turn into a black goo like most wet lubes, and it's also not as 'attractive' to road grime as some of the dry-lubes. Lasts about 300 miles (< 50 degrees) - 500 miles (> 50 degrees) between applications, unless you end up in a downpour -- in which case it will be washed-off in about 30 miles, i.e., not recommend for use in wet climates. I keep a small bottle of Pedros Ice Wax in my seat pack or jersey pocket when rain is likely. Cassette and chain get tossed in citrus degreaser bath about once a month, then hosed off. Cassette air-dries while the chains go into a cold Fry-Daddy filled with a mixture of paraffin wax, petrolatum, mineral oil and then either some beeswax or powdered teflon -- depending on the time of year. As the Fry-Daddy heats up the water is boiled out of the chain by the hot wax bath which works its way into the pins and rollers by capillary action. The chains are pulled out to cool off stacked in a pile so as not to squeeze out any wax. It sounds more involved than it really is, but it's a process best practiced outdoors or in the garage by bike geeks. We have a small fleet of 7 bikes, including 3 tandems with their extra timing chains, so multiple chains are "cooked" at the same time assembly line style.
As for the frame and other components, the painted road bikes used on the weekends only get washed after a nasty ride. I use citrus degreaser on the mechanicals which is applied with a heavy parts brush and then hosed off. After a sponge bath with auto car wash soap, the frame and shiny bits are cleaned with Meguiars "Cleaner/Wax", followed by a coat of polish, and then a coat of carnuba wax. About once a week or after a long weekend of riding I use a spray-on "detail" wax to clean the frame.
My daily rider is a Ti Dean Castanza that gets washed when it rains. However, the drivetrain gets pretty good attention at least once a month. Mountain bikes and their anodized finishes are similarly neglected unless we end up mud-bogging but, the drivetrains get hit with a dry or wet lube on a regular basis and cleaned before they get bad enough to create bigger problems.
