951 RAVE Valve cleaning

Resurrecting my 2001 XP, I pulled the rave valve (and blade) out of the housing. The blade is caked with carbon . I will clean the RAVE valve pieces and blade, but is there anything I should do to in the channel where the blade inserts into? Carb or brake cleaner or will that just put all that carbon into the engine (at one time) and cause more issues?

I’ve cleaned many rave valves but also wondered how to clean the slots without everything falling into the cylinder.
If there’s not an easier way, For the heavily carboned ones I wonder if it would be worth it to remove the cylinder cover, lower the piston to the bottom, place a couple rags in there and then clean the slot for the rave valve, then just vacuum out the debris.
