Back to the original question.
I have some commercial turbine wash but have not used it yet. One of the A&P mechanics gave me a gallon to try out. As soon as I get some more flights with my 500, I'll give it a try.
The procedure is to spray some of the stuff in the compressor section, let it sit for an hour, and then run the engine. The full scale guys love it.
It's supposed to be environmentally safe enough to drink, not that I'd recommend that.
And before anyone asks, I don't know what it's called?
