I cover up battery and the ECU area, battery you dont have to cover up but only if you want to, use a de gresser, spray it on, dont let it set to long otherwise it will less streaks/stains in the black parts, I use a wash mit plus other soft brushes, and then after de gressed wash off with autoglym shampoo wash all over, dry off and then dress all the rubber and black parts with Autoglym bumper care...

Some say its not safe to jet wash but i cant see the harm if everything is covered up.... I good de gresser is GUNK engine degresser but it does leave streaks so dont spray it on and leave it, spray it on let it settle for a few seconds then with some brushes rub it in, first jet wash to the best all the dirt and grime off then do that...

Then I go somewhere other than my drive and use a water bottle with a hole pierced in the top to squirt the gunk off. For nasty bits get in there with a washing up brush after giving the gunk a while to work in. once the major gunk is off get in there with a WHITE teflon safe scourer and washing up liquid using the bottle again to squirt it off. Probably easier to use other peoples methods but I like to have control over where the water goes.

Didnt know that. Mind you I doubt there is much original wax left by now moving this thread to the relevent section.

Even before considering jet washes/gunk etc spend a good couple of hours with some various rags/brushes and clean as much visibly as you can. Most of it is just dust or a film of dirt, I normally find a brush and a couple of old microfibres make a good start. Mild car shampoo and a damp cloth used locally on a cloth can easily clean all of the panels, inner wings, underside of the bonnet, around the grille etc etc. If you really need to wash off some dirt, as Michael and others have said, it's important to re-wax everything afterwards. It is after all an engine bay, it's a working machine and the benefits of making it look shiney can be easily outweighed by the risks of damaging stuff with over-zealous cleaning efforts stripping wax protection and blasting water where it doesn't belong. Water can get into electrical connectors, wax can be removed from where it belongs, high-pressure water can be driven into bearings and even damage rubbers etc. And please don't go near cars with washing up liquid - as Richy and Stu have said, it's for stripping grease off dishes and is full of salt! Easy does it IMHO Will
