A garden hose in not necessary. A pressure washer opens up many doors to stupidity. If you are smart and have the preparation, and restraint then I guess you could pressure wash it. But you probably should know where to spray, is the engine hot or cold, how close can you get, how to dry it afterwards, any water left that can puddle up and cause rust on down the line, etc, etc
Using a hose or pressure washer ONLY (IMO) speeds things up. If you don't use a heavy hand or erratic motions then you are almost set. Know which chemicals are ok. Dont be careless and bump into delicated fuel and electronic connectors and such. So, if you just use cloths and spray bottles you can eliminate some of the danger of water.
If you have time just put on some safety glasses, pop the hood and get a water dampened soft cloth (microfiber) and clean. Then, maybe add some drops of car soap to the bottle......then a little armor all here and there. Wax the painted areas, grease or oil on moving metals. Just don't mess up, get in a hurry, be too rough, use the wrong chemicals!
