For pine sap on metal or fiberglass, naptha (main ingredient in charcoal starter and Coleman lantern fuel) is usually safe on any cured coating. Turpentine would also be good (May screw up a spray bomb DYI camo job, though). Alcohol may work but probably won't dissolve the resin as well, but it may get off the stinky naptha or trupentine smell on a hunting bow.
For a wood bow, which may have a varnish, lacquer, or shellac finish, you need to be more careful. Anything you try should be be tested on a small inconspicuous spot first. Naptha and turpentine can cause varnish to dull or check. Alcohol will dissolve any shellac, even if it was just used as a wood sealer before top coating. WD-40 is probably a safer bet, but moisten a rag and try it first.
Rubbing with a paper towel can be somewhat abrasive (paper is made from wood fiber), so don't rub too hard or you may change the gloss of the original coating (make flat coating more shiny and shiny coatings dull). The automotive clay bar may have the same effect, as will hand cleaners with pumice in them, so use it with care.
Goo-Gone and citrus based cleaners work well on sap and glue residue, but the above cautions still apply.
The most sensitive areas with any cleaner or solvent are going to be the logos and decals. The logos may just be sprayed on ink, in which case any of these may just totally remove them. Any of the solvents may cause the edges of decals to dis-bond as well as start messing up the dyes used to color them.
Best to keep all of them away from the strings and cables. Best thing to get sap off them is just keep working in the string wax.
SO after saying all may cause problems, if it were me: For globs of sap, I would scrape as much off as possible with an old credit card or other plastic tool. Then, and for the large areas like where your sappy gloves or hands have left a bunch of sticky areas, using a cotton rag I would try: WD-40 first, naptha second, goo-gone or citrus hand cleaner third, Soap and water after to neutralize it and get the smell off. For oil or grease, I would probably go with alcohol first.
