Working with helicopters in the military, we routinely do engine washes. This is done every postflight, and after every "boat flight". The reason we do it after every boat flight is because of what we call "salty hover". To let you know, I am a flight mech in the coast guard on the dolphin aircraft. The reason for washing the engines is for salt ingestion. Now to the point. Obviously we dont hover our F-100's hover the salt water and worry about salt ingestion. If anyone does, can I see the video?!?!?! Does anyone out there wash your turbines after so many flights? The way we wash our engines is just to spool them up, fuel off, with water running through them for 20 seconds, wait 5 minutes, then run engines for 5 minutes to dry them. EVery so often when one of our engines seems to lack power, we will wash them with plain old general purpose cleaner. Has this question ever been brought up before? Comments questions and concernsj are greatly appreciated.
