I've sprayed into the turbo.. not an issue. CRC was originally called intake valve and turbo cleaner. I would have no issue using ANY of the cleaners into the turbo and do so!
Start by making sure you remove as much 'carbon' from inside the engine. This is by running a quality fuel system cleaner for a full tank BEFORE even starting the procedure. This is when you toss in a big bottle of Techron concentrate, Amsoil PI, Redline SI1, STP5in1, Gumout Regane, RoyalPurple, 3m, Lubegard, Seafoam, or Berrymans.... at your next premium toptier fuel fill up, and then run the tank empty.
And then, since some spray IV cleaners use solvent carriers and can cause detonation, fill with a quality premium fuel for your IVD cleaning. I get the 93 octane PI/detonation reducing fuels from ExxonMobil, ChevronTexaco, and Shell. Obviously, some states limit octane so pick the best locally available toptier stuff.
You'll will need a helper for RPM control for some products that might cause the engine to stall. This is when you spray for 5-10 second bursts on and then off again. Budget 15-20 minutes for spraying. Other products use more 'alcohol' or 'gasoline ingredients' as a carrier, or do a better job misting the solution, or have a lower nozzle feed rate, so that it doesn't bog the RPM down much. I don't have brand loyalty so use whatever IV cleaner is available around you and read the directions.
After emptying the can into turbo, shut engine down and let it soak. After a soak, longer the better, take it out for a gentle ride. Any residual 'condensate' will find its way thru the manifold and thru the engine. Don't be the foolish pedal-to-the-floor-yahoo creating a smoke show in rush hour traffic. Drive around for 30 minutes with a light gentle foot on egg shell pedal, and during that trip, slowly increase go-pedal application and engine rpm.
Then, go home and change the oil and filter.
