If you don't ever plan to use a Shimano Flight Deck computer then just cut the ribbon, pull out as much as you can and tuck away the rest. We don't bother trying to pull off name plates. But we do remove the lever/pod assembly from the body, if the tiny pivot set screw will loosen. Using a sharp/not worn or ball ended hex wrench helps here. We have never seen a face plate be damaged with the industrial solvent tank soaking we use. Or with Clean Streak, WD40 and Thrust. Andy
Thanks, this sounds pretty straight forward. I’m going to see if Simple Green won’t get the job done flush-wise.
I wanted that wire harness out! Although once I realized that the lever bodies would feel strange without a cover for the electronic bits, mounted under the hoods, I figured I would just leave the wire.
