Engine Bay Cleaning

I want to clean the engine bay of my 2005 Civic. I purchased Autoglym
Engine & Machine Cleaner but was concerned when I read the
instructions it said to hose with plenty of water to rinse off. My
main concerns were water ingress into air vents and electrical
components. Can someone please advise which areas I need to cover with
cling film. I've attached a photo of my engine bay. Maybe someone
could be kind enough to mark the regions with red circles in
Photoshop.

Many thanks for your help!

I would just leave it alone if it were me.

 

I went ahead and did it. I covered all the water sensitive components
with cling film and aluminium foil. I sprayed the entire engine bay
with Autoglym Engine & Machine Cleaner and wiped over with several
wrung out damp cloths and a bucket of hot water. I then sprayed the
bay again with Autoglym Rubber & Vinyl care. It started perfectly the
first time as normal.

Here are the results:

Amazing transformation.

 

Now if only you could figure out a way to ride around with the hood up to
show off your work...

 

Good one.

 

Easy -- commission an aftermarket clear plastic hood. Heck, there may be
something like that already.

 

Nice!

 

Whoa! Can you still start up and run that beautiful engine?

 

Yes of course - it started perfectly as normal the first time. I
covered all water sensitive & electrical components with cling film
and aluminium foil. I wiped over all the surfaces with a damp cloth
rather than hosing to rinse.

 

Good for you, but I never heard of cling film before. Where do you get
it?
How much time did the whole job take for you?

 

Saran Wrap

 

Not as long as I thought - about 1.5 hours.

 

Amazingly fast! Maybe I should hire you out to do the same on my Accord.

 

Oh!?
