I would like to clean the engine bay of my car,

Is there a way to do this without buggering something up. I dont want to jump straight in there with a pressure washer incase i do damage.

Cheers

Cover your alternator and alarm sounder if its visible. Spray on an engine degreaser...Comma Super clean / Gunk or your preferred choice. Use a low pressure hose to rinse thoroughly. Repeat if necessary using a brush for difficult areas. Start engine and allow to idle for 10 mins, bonnet down. Spray engine bay with your preferred dressing. Leave for 15 mins to dry then look and enjoy. Go and drive.

i use an alkaline solution such as steam cleaner soap and brush the engine bay with it using a 3" paint brush then rinse off with a hose (no pressure) only do this when engine is stone cold tho as it will leave white water marks if its hot.

Use use duck oil, it has various uses..
First spray it on and let it soak into a cold engine.
start the engine, then get blasting with the pressure washer.
Doesn't make the slightest difference if you get the alternator soaking wet or not. (my
Alarm I do cover up though. )
If it's seriously grubby a second coat of duck oil and wash off again, very rarely do I get in there and scrub anything manually..
if you have a home compressor then attach a blow gun and blow the water droplets off, you don't have to be too fussy.
Final application of Duck oil for it's water displacement properties and to create a bit of a sheen to everything.
Shut bonnet and test drive at speed (the final blow dry process)
The only thing that occasionally gets too wet is under the coil lead ends, this'll cause it to misfire a little, no amount of driving will cure this, you need to just pull the boots of the leads off and get either some wd-40 in there or the aforementioned blow gun.
Job done.

I use Muckoff (the bike cleaning stuff) for my engine - good spray, leave couple of minutes - brush any dirty bits I can get at.. rinse off with a watering can..
