As above,  what's the best way to clean this often neglected area and keep it looking great?

No one bothers to clean the area under the bonnet?

I get mine steam cleaned at local wash shop, but I make sure they're aware how precious the cargo is.

Whenever I've cleaned the engine and bay I've given it a light spray of degreaser (Gunk etc), a quick brush to loosen up the grime, and then used a pressure washer carefully.  I have the engine running whilst using the pressure washer and take care not to get too close to the alternator.

For me it's a good circus based APC diluted to about 4:1, followed by an application of CarPro PERL.

So i tried cleaning it by hand which was laborious, but it has come up a treat. Next time i will use a degreaser and carefully hose it down.  Just not brave enough to use the karcher on it.

Is that the one with the big top? Just clowning around :)

I just cleaned mine by hand, with a damp cloth & washing up liquid - it's not hard.

One top tip is that I used Hammerite black paint (hammered finish) on the metalwork that comes into contact with the rubber seal of the bonnet lid and it looks great - cleaned up an area that was looking a bit rusty and matched really well.

I used to clean my e46 330 engine by covering it in engine de greaser  (meguires) giving it a good agitation with a detailing brief then hosing off with a pressure washer.
I'd dry it out by running the emgine then dress it with 303 aeorspace protectant

Dodo juice crudzilla is an excellent product for stuff like that.

I was thinking of getting some of this for pre cleaning the lower half of the car.  Any good?

Best stuff I've ever used.  Just a warning though unlike most of there products this one will strip your wax finish off as well, but a really good cleaner.  I've always been impressed with there products the colour changing alloy wheel cleaner is the best I've ever used to.

I moved away from the high pressure hose years ago with the engines being a little more sensitive to the water nowadays.

After whatever product you put on it, I use a very low pressure spray in a container to get very targeted water jets.
