If you have excessive grease or oil, you have a problem that needs fixing. For more severe deposits I use Gunk (non-foamy) engine cleaner which I think has a lot of kerosene or something in it. You can carefully spray it where needed.Thanks for the replies. So, it is not bad for the engine to rinse it off with a hose?
Here is a link to the thread:....I typically use a 1:4 dilution of Meguiars APC+ and/or car wash soap in most cases. I also use a variety of brushes. I spray the engine down, apply the APC+/soap, agitate & then rinse. I have filters that help avoid spotting but I still dry the engine. I use a blower and compressed air followed by an MF towel to sop up any remaining spots. I follow up with 303 on the plastic bits and wipe to a satin finish. I don’t have pics of our Forester but here is my 6 1/2 year old WRX:

A quick Google shows a lot of differing viewpoints on this issue.Simple Green is said to be bad for aluminum. They do make a variant intended to work on aluminum. I would stick with something intended for auto use like P21S.
