Well finished fitting the eibach pro kit today which went ok with no dramas :) so while i am waiting for my new front discs/pads to arrive i was going to give the engine a good clean and also underneath a proper going over i was thinking of gunk and a pressure washer thats after i have got it up on the axle stands to get good access....what do you guys think is there a better way :roll:
 
Personally I wouldn't use a pressure washer. Some degreaser and a normal hose with spray nozzle. Finish off with some Aerospace 303 to make it look nice.

I bought a 5 litre bottle (eBay) where I put in hot water, it is like a big plant spray which is useful to clean at low pressure.

Use AG to wipe it afterwards.
 
I use some APC with detail brushes and a hose on fine spray. after that I dry off and use some engine spray stuff I've had for years which makes it looks matt black like stock. Keep on top of it once a month, 5 mins and its always in good shape.
 
I popped the bonnet last night with the intention of blasting some bits with a handheld steam cleaner... but as I've only had the car for a day I just didn't feel confident enough blasting the engine with water.
Are there any specific areas (electrics, harnesses plugs etc) within the engine bay that shouldn't be directly exposed to water? I know that over time it's difficult for water to not make it in there, but I'm thinking of areas that aren't designed/advised to have water directly applied.
 
The battery is in the boot which helps. Stay away form the Maf as much as possible. I don't plastic bag it but I also don't point the hose at it. You'll be fine with a light hose though.
 
Simple green works great as well in removing dirt and grease. Just be careful not to use it on bare aluminum pieces because it can speed up the corrosion.
