Any advice on what the best way to clean your engine. What to cover. What parts are ok to get wet...

I've hit mine several times with hot water pressure washer with no issues . Dont blast things up close where electrical connectors live or you might force water into them and be careful around the fuse box and ecu area. avoid hitting a hot engine If you use a cold water pressure washer.
I've used this method for 2 and a half years on my si. Engine bay looks brand new still

A damp rag works fine. No pressure washer, ever

From page 621 of the HB owner's manual:


• Do not spray high pressure water directly into the engine compartment. Instead,
use low pressure water and a mild detergent.

Have you seen any bolts start to rust from doing this?

I hit mine up with a high pressure air hose and wipe the rest. I do it 2-3 times a month stays clean.

I keep mine clean with a variety of either dry or damp microfiber towels, air hose, and a shop vac. I find it you're proactive with cleaning it, it truly never needs an actual wash from a hose.

I did that actually for the 1st time last week. I used a hose, no pressure washer, to knock off loose grime, then I sprayed on some all purpose cleaner (Simple Green, diluted to 50/50 by volume), and then I used a brushed, and I finally sprayed water again to rinse.

I stuffed the intake box with plastic bags just to be sure I woulnd't get water in there by accident
