2005 Engine Bay Pressure Wash?

[AndrewButler05]

Has anyone pressure washed their engine? I watched a couple YouTube videos and as I assumed it would be smart to stay away from the fuse box and Distributor. My question is the Alternator...? Being that it is located on the back side of the engine and away from normal road spray, what should I do? It's not like it's on top and is the first thing you see when raising the hood and I could simply wrap it. I haven't changed the stock air intake so that won't be an issue.

I was considering doing this when Spring comes and clean it up a bit. I was curious of anyone had done this, and if so, what's the best way?

Thanks,
