Haha funny stuff in here.
Protour bike chains are replaced fairly frequently and the factory lube is pretty good stuff. But since the bikes are routinely washed after a day of racing (sometimes even power-washed), they do get a wipe down then the chain is relubed and wiped dry of the lube the night before. This gives the lube time to penetrate and the volatile parts a chance to evaporate. Generally once a chain is pulled from a bike it gets discarded and a new one is put back on. (They don't use quick links on their chains.)
The lubes are often custom mixes of the mechanics, and get thicker (more viscous) on rainy/dusty/grimy days in the saddle. Sometimes you will see a rider getting a squirt of lube on a chain from a team car. This is fairly common, especially in big races.
A dirty chain is rarely cleaned with a degreaser as this will dissolve the factory grease that is inside the rollers. If a chain is that dirty and cannot be surface wiped clean, generally it will be replaced.
Power washing your bikes is Not recommended, btw. This is done for sponsors and to make things look good, and plus these bikes are frequently broken down and rebuilt/re-lubed, especially the BB bearings and the headsets.
As to chamois cream. Some guys are sensitive to saddle sores, most not so much. When you put the amount of miles these guys do in the saddle, you sort of get used to it after years and years. Sure every once in a while a hot streak of days will happen and you sweat a lot, or you forget to wear a clean set of bibs and you get an infection, or it just happens, but it is not the norm. The problem with a saddle sore is once you get one, it is hard to get rid of it...you have to keep the area super clean and as dry as possible. But yet during the day, you are sweating in your chamois, abrading the area, and just generally not letting it/them heal. The best way is to prevent them in the first place. Chamois cream is really for occasional riders who are not used to the miles and get chaffing issues. Chaffing is not so much the issue for pros, as I said, they are used to it, it is more the long term (5-8 hours a day) exposure to bacteria/sweat infested chamois. Riders tend to be very particular about their bibs: they must be clean and fresh. While I no longer race, I would never think to own just one or two sets of bibs for daily riding. I also get a kick about guys who complain about sores, yet wash their one set of bibs in the shower or something! They need to be properly washed to kill all the nasties that try to make home in chamois.
As to the story of applying chamois cream in that fashion, no way, doesn't happen as far as I am aware, nor have I ever heard a story about it ever happening.
