I just use regular degreaser and spray the whole bay with it, let it sit for like 5 minutes and use "mist" mode of my water spray to wash down the grease. Right after that, I use compress air to blast water off from all electronic wires and connectors asap to make sure no water gets in there. Then I use a dry towl with Maguire quick detailer to wipe down any excess grease / dirt that didnt get wash away. The last step is to spray the entire area with engine wax (my wife's dad has a bottle of it, not too sure where he gets it from

but if you want to know I can ask him) to give it a good deep shine.
So clean except for your PS/Brake Fluid resivoir!!

lol I tried but cant get my hands in there unless I remove the tower bar...too lazy to do that
