If you keep it clean it'll be all right. I was a daily commuter for 20 years. My commuter was a steel frame with rather nice components. I never had a problem, but I cleaned, especially the running gear, scrupulously.

I live in Rochester, NY. I ride commute by bike every day--rain, snow, wind, salt, and even on the occasional warm, dry and sunny day. Clean up after every dirty ride, and it will be just fine.
In the winter I even put fenders on my fair weather fun ride bike, just so I don't have to wait for the roads to be clear and dry--clear will do. Not that my main bike is a beater--far from it. (Beaters are for drunks and the homeless, IMHO) But just so I don't have to swap the studs on my main bike.
Other than fenders, my fast ride, fun bike gets no other "winterization".
My main commuter gets studded snows, larger fenders, and I switch from ProLink to a "wet" lube. That's it.
On those days (like yesterday and today) where the road is dry, but white with salt, and you can taste it in the air, I don't do any more or less than I do after any dirty ride. I hang the bike in the shower, and rinse it down, then let it drip dry.
Here's my primary commuter, an '06 Trek Portland, getting cleaned up.
A couple of times a week, I relube the chain and once a month it gets a soap and water bath. In spring, all the bearings are cleaned and repacked, it gets new cables and housing, and a new chain. I also give the RD a little extra attention. Nothing more than most people do in the springtime anyway.
The point is, the worry warts' scare stories have no basis in reality. If I can ride my bike five or six days a week through Rochester's worst with no problems, you certainly can take your carbon wonderbike out on sunny dry days (if we ever get any) with no lasting harm either. Go ride yer bike!
