For narrow stroke graphics I use solid rubber or flap vinyl removal wheels on a variable speed grinder. Make sure you use the appropriate RPM and pressure to avoid melting the poly. For wide stokes I prefer a heat gun and some spare time.... Finish with some adhesive remover (test in a small area 1st). And clean with something intended to clean poly/ acrylics/plastics. Some solvents make cause poly carbonate to craze. Example: Windex w/amonia, laquer thinner, ect..
Depending on how long the graphics have been on and sun exposure I would expect the area behind the graphics to be several shades whiter as poly yellows quickly when exposed to UV..
Good luck.
