Stiff fd shifter
On a recent ride the FD became hard to shift from small to large ring. Shimano Ultegra STI 6800.
Removed the wire from FD and shifter works well. I can also move FD easily by hand so wire drag is suspect.
The Cannondale synapse has internal cable routing, but the guide and the wires are exposed underneath the BB cavity. The FD wire emerges through a small guide above the BB cavity.
Any suggestion how to clean this area without removing and rerouting the wires?

Check inside your shifter for the wire fraying; if it has begun to fray it will be a heck of a lot easier to replace it BEFORE the head breaks off than after.

Welcome to the cost of internal cable routing. I suggest replacing internal shift cables far more frequently then externals usually are. Andy

Replace cables and housings.
You're only (real) choice. Everything else is a bodge.
It's not hard to do really. It depends on the type of internal routing you have.
If your cable is bare inside the frame, then the bike will have removable plastic pieces which will allow you to easily "catch" the wire inside the frame. Or, when you pull the old cable out you can tie a string to the end of it. Then you use that string to pull the new cable through the other way.
If the bike has full internal housing, then you pull the cable out, replace the cable, then pull the housing out (the opposite direction) (while keeping the cable in the frame) and then thread the new housing onto the cable in the frame. The cable then acts as the guide for the housing.

That's what I have on my Cannondale. Unfortunately, the plastic cover was never installed so the exposed guide and wires accumulated some dirt. I tried to clean the guide and wires, but then decided to change the wires, and do a more thorough job. This set up is quite convenient.
Thanks
