How Do you Clean an Engine..Exerior??

I know the best way would probably be some brake cleaner and a toothbrush (just watch the hoses) but is there an easier way?? Ain't there places that specialize in this?? Can i just get a strong PSI water hose and spray her down?? What soap?? If any.. My friend says to just leave it, cause if you get water in somewhere your f*****. But then again, everything is SEALED. So the nothing would get in. I know dealerships and used car lots clean engines like this..

BTW.. 95 tbird 4.6 V8

Just get some engine cleaner from Checkers or any parts store. Spray it all over the engine. Let it a few minutes and then just hose it off.

I used the Gunk brand engine degreaser and it worked very well.

Just make sure your engine is cold before you do all that.
