A couple cans of VERY STRONG gel degreaser and a power washer but you'll be sorry.... :P

Seriously, For the first wash I've always had good luck with a strong gel degreaser such as that made by Engine Brite and following the directions to the "T". Cover the Igniter, coil (or coil packs), distributor (or CPS), alternator, etc. and hose off anything from the head up with just a mist or shower setting on a garden shower head... scrub any tough residue with a dish brush from the kitchen. Below the head using a more power sprayer is fine but be careful of over spray soaking something it shouldn't (not a power washer though, just as much pressure as your hose can provide).

Wait a week and repeat if needed. This way any small amounts of water that did seep in where it's not wanted will have time to evaporate and you avoid shorts due to the water accumulating.

After the first couple washes a light biodegradable degreaser and a hose with the shower nozzle every month or two will be sufficient to keep the bay clean. Don't get in the habit of doing it all the time, you'll dry out belts and hoses. I wash mine once every 3 to 4 months, sometimes longer. Dust accumulates but I still get compliments on how everything is "spotless".

i see thanks for the tip. i cleaned mine once and my supra started acting funny it seems water got in somewhere and it sounded like an old truck and would hesitate on acceleration.

auto parts store
I cleaned my engine bay on a white 89 mk3 with engine cleaner, a rough sponge (one that you would clean a pot or pan with) and a tiny bit of water that I used VERY CAREFULLY.

Gunk Engine Cleaner Foamy edition. Buy this at any auto parts store, I cant remember how much it is but it isn't expensive at all. It has a blue lid. can is blue orange and white. The same company also makes a degreaser that works well but just the Foamy edition should get the job done.

To use: spray it in a small area, then scrub with that rough sponge. the more elbow grease the better. after you are done scrubbing, take a small bit of water and just kinda rinse it off. Repeat it a few times and BE CAREFUL AROUND ELECTRIC. YOU COULD SHORT SOMETHING OUT. I did my whole engine bay in about 90 minutes and then went to a car show!!!

Apply degreser, wait for a few minutes then hose it off.
