On the top end, many have had good results using a mild degreaser like Simple Green, full strength over just the scantiest misting with water first, engine warm but to the touch yet. (Quick: what's that scent?)
This gets the dusty stuff and general dirt.
Lower down like on the oil sump and engine mounts & block, Castrol Purple Power is effective; kerosene is good (think "Gunk", which is kerosene in spray form).
The Purple Power doesn't take too long to penetrate and loosen. It won't hurt the red oil sump, but I have had it remove some black paint on a few throttle control components on my '96 Avalon recently. Do Not get it on the body paint. It strips off the was and usually streaks the area with dull rivulets where it had the chance to run down the fender, for example.
I really like the Purple Power for degreasing the oily grime. Just be aware this is rather astringent, like what happens to your hands when you peel and eat an orange -- dries them out, you know? PP does that permanently to painted and bare metal surfaces and leaves whitish traces, like calcium or salt deposits.
On some areas you still need to brush. Other places, maybe need a wax/grease remover by hand, like underside of hood. Rewax places like strut towers, underside of hood, etc.
Not sure what works to shine up things later. I am sure there are some products out there which do a great job shining up hoses, plastic and metal. Personally I avoid silicone products anywhere on my cars.
I am new to the 740/760, but my '86 240 has the B230F w/o ABS. So far, I have not found anything you need to worry about electronically. Some cover the ABS and brake bottle.
Be careful around any wiring if using the pressure spray at the local car wash.
I live 2 mile fro one, so I remove the plastic skid plate, apply the Purple Power and/or Simple Green, then use the car wash wand at low power on its engine degreaser setting, then rinse.
