Super 6

I was reading the article ESP recommended on the Super Six and came across this line.....

It always helps to have the parts and the motor as clean and in as good a condition as possible. Working in filth is never fun. I like taking the car to a coin-op car wash and using the high pressure soap and rinse settings to de-gunk my engine and engine compartment.

Has anyone ever de-gunked their engine this way?
