You don't say how much carbon? Carbon buildup slows the spool up of the turbine.....
If you want to clean it, you will need new gaskets......for the housing.....but there should be no problem in cleaning the rotor......some carbon solvent, carb cleaner....and a little brass wire brush....and compressed air......but if you do clean it....make sure that you do it well.....the carbon deposits there were accumulated at high RPM.....so they are sorta dynamically balanced......so if you don't clean it completely, you may wind up with a vibration problem.........just be careful, don't bend any fins......
Oh yes, mark the housing before disassembly so that you know which way the spigots go when reassembly......

Note: I used to have my engineers disassemble and clean my auxiliary/generator engine turbos, whenever the exhaust temperatures began to climb.......the main propulsion engines had water washing connections, for washing while running (at reduced load) and we used to do this after long river passages, or just before we headed across the Ocean.....also of note, there are some that inject crushed walnut shells into the rotating turbo.....supposed to clean them like bead blasting
