I'll bet the washing away was on a rotating valve.

Once assembled the sealing of the common fuel injector is static unit load, 
rather than dynamic. Even if it is washed away the squeeze has been 
established in a dynamic environment and will suffice.
I have used Dow vacuum grease since my gas turbine days in the early 70's.
OEM's don't use anything exotic to my knowledge. If I remember correctly it 
was just a soapy solution when I worked with Lima engine plant on 2.3L 
intake manif assembly process.
Fuel leaks were VERYVERY LOW incidence. (no warranty)
I use the Dow silicon for assembly on methanol and gasoline injectors.
