I found this rather exhaustive article, which is below:
Many car, truck and RV owners spend hours cleaning and waxing the exterior
of their rigs, but do not give any more attention to things under the hood
beyond checking the fluids periodically. There are many reasons why it is
important to clean the engine and its surroundings routinely. A clean and
tidy engine compartment makes it much easier to detect oil and fluid leaks,
damaged or worn drive belts and rust or battery corrosion before they lead
to more serious damage. And if things really get out of hand, the dirt could
provide fuel for an engine fire.
Cleaning the engine compartment is not that difficult and unless you are a
perfectionist or plan to enter the vehicle in Concours d'Elegance
competition, it does not require much elbow grease.
First, warm up the engine for a few minutes. This will help soften the
grease and crud. However, do not let the engine get hot. Never spray water
on a hot engine since sudden temperature changes can cause serious damage.
Also you can get serious burns from hot engine parts.
Next, cover critical parts of engine with plastic bags and rubber band to
protect them from water and other liquids. Either cover the air intake and
filter or remove it and cover the opening. Protect electrical components
like distributor, coil and fuse box. Use rubber bands to seal the bags
around the components. Check the oil filler cap, the power steering filler
cap, oil dip stick, etc. to make sure they are tight.
After everything is sealed up, spray the engine, accessories and surrounding
components with a high quality non-petroleum-based degreaser that will not
harm the paint. After letting the degreaser work for about five minutes, use
a soft brush, a paint brush works well, to loosen up the crud. Respray with
degreaser and rebrush if grease and grunge remains.
When the entire engine and engine compartment looks pretty clean, rinse with
lots of water from your garden hose. If you can, hook up to a hot water tap
since hot water will do an even better job. Better yet, do the job at a do-
it-yourself car wash which usually has higher pressure hot water and is set
up to handle the dirty water in a more environmentally friendly way. Even
though the degreaser may not contaminate the ground, the nasty stuff washed
off can get into the groundwater supply and do harm. Many car washes have
equipment specifically for cleaning engines. If you want to use a degreaser
that you know is safe, I only use the facility to rinse with plain, hot
water. Clean the engine first and wash the vehicle after cleaning the engine
compartment making sure all overspray of the degreaser is removed. Since
all degreasers will remove wax, plan on rewaxing after cleaning the engine
compartment.
Once the engine and compartment is clean, immediately remove all plastic
bags and rubber bands. Dry standing water and aluminum parts with a soft
cotton towel. Start the engine and let it to warm up to dry the rest of the
engine as well as evaporate any moisture that may have collected in electric
parts. If you do not start the engine immediately, often moisture will seep
inside parts and it now will take a long time for things to dry out. If
this occurs, use an ordinary hair dry to heat ignition systemparts like
distributor and coil.
Once everything is dry and has completely cooled, you may want to coat hoses
, weatherstripping, shields, gaskets and other rubber parts with a rubber
protectant. However, do not use it on rubber belts since it could cause them
to slip.
