Will degreaser harm paint?

I'm using Finish Line citrus degreaser. Can using it to clean my frame (for stubborn downtube grime, especially) end up harming the paint if I don't rinse it off completely?

Read the label on the bottle.

The bottle warns against using it undiluted on rubbers, plastics, and polycarbonate materials. No mention of paint. Just looking for reassurance that I'm not harming my bike's paint job.

Probably not. Most of the water soluble degreasers are detergents that don't do much to paint. You usually need a very aggressive solvent to dissolve the polymer film that is paint. Test it on a part of the the bike that won't matter (bottom of the chain stay, bottom of the bottom bracket, etc) for a short amount of time. I doubt if it will do anything but to be safe do read the label.

It may not hurt the paint, but decals may be another story. I used to use gunk degreaser on a bike to clean it. It did a fine job, but the decals started peeling off. I don't use gunk any longer.

Carbon frames?

Actually, this raises a good question - will these harm carbon fiber components? I haven't seen any negatives, so I assume no.

Gut feeling? Probably not. You can check here for a list of stuff epoxy doesn't like. Methyl cellosolve seems to like epoxy...in a bad way. Lots of the 'green' cleaners have butyl cellosolve in them so you might want to be careful. However carbon fiber usually has a clear coat over it to protect it, so that may not be an issue.
