If that does not remove the really heavy deposits, do it again and scrub specific areas with brush. ALWAYS clean engine cold and use low pressure water for rinse.

Hmm, didnt know that about the SG. I its the only general purpose cleaner I have down in the garage....dman it.....gotta think back if I used it on anything aluminum.

Thanks

I dilute the Simple Green to about 3parts water to one part SG. I also take the fuel rail covers off to ensure that the engine is rinsed thoroughly. Don't let it stand for longer than 10 minutes. There is also a product called Extreme Simple Green that is safe for aluminum.
