Simple green has a fairly mild PH(9.5), compared to other cleaners which have a PH of 12. One of simple greens main purposes is to clean engines, so it safe, its a very big company and i like their products, i really like that they are enviromentaly friendly. I dont doubt your info though, it makes sense,where did you get it.

WOW! This was interesting a lot of differences. I have learned a great deal from the demo video clips. I am sure it would help a lot of us out. Who does those clips? Anyone interested in making one?

I just spray a good degreaser on the engine, then spray with a garden hose on medium to foam it up, then spray it off. Never had any trouble on any of our vehicles, newer vehicles are pretty well protected. Now I don't just force water into the alternator lol. This is on everything from our high end sports cars, to Ford trucks. If you keep your engine clean, Armor All Tire Foam (regular) is excellent as it cleans and protects leaving a nice look.

This is what I do as well. There are risks with using water, but it does the job most thoroughly after soaking with a good degreaser. I always use a low power pressure washer (1300-1500lbs), do not put the tip directly on any parts(stay AT LEAST a foot or two away). Pressure washers use much less water(1 to 3 gallons per minute) than an opened ended hose, which uses 7 to 25 gallons per minute (free flowing or trigger sprayer), so pick your poison;) I consider myself to be lucky thus far:D, and I've done a lot of engines.

I found out some reason why a car didn't start after washing the engine bay. It was either done by blow fuses due to the water make a path for it the connection to short, and corrosion on parts and contact areas.

Also I always make sure the engine is dry to, cause I don't want the water in my engine bay to condense on or in a electrical connection.

The way that the BMW dealership does it down here is they turn the engine on and clean the engine bay while its on. I dont really like this method because some times the degreaser will dry up and also you are pouring water onto hot engine parts. Some times i will start the car up afterwards.
 
Wow, never expected this when I put the question up!
