What are you guys using to clean your engines? I've used the "engine degreaser" from autozone that is basically kerosene and other petroleum products and simple green at 1:3 ratio.
Now that I've added some more chrome/billet to my engine I was thinking about cutting back the ratio to 1:5 on simple green and using a pressure washer with all my electronics and air filter covered up.
I like to use scrubbing bubbles and a hand spray bottle. It works great. I didn't belive it until I tried it. I use it all of the time on my stock vehicles. I don't know about chrome, but it doesn't hurt the shower fixtures
