Depending on the day of the ride, sometimes there's a lot of road grime that gets stuck on the frame, most common is the down tube, bottom bracket, and chain stays. Even the under side of the saddle and seat post gets crud from the splash through puddles.
That road grime is like sand paper if you wipe it down with any type of material in a vigorous manner. I use the rags they sell at the auto parts store, the cheap red one's from India. But its more important to first examine the bike for the type of road grime that on there and how you go about removing it. Its not that important about the fancy types of cloths to do the job.
If i know there is a lot of grime or big chunks of dirt, I carefully wipe it off with a wetted down cloth. I rinse the cloth to avoid the "sand paper" effect. Most carbon bike frames have a clear coating on it. What you don't want to do is to create scratches on that. After the wiping is done, and once in a while I use the Meguiars spray on auto detailer to give it a nice shine
