Vacuum is not anywhere as efficient.


Best solution is to use a hose pipe with a pump to wash out everything
in the computer. Alternatively, put the machine in a bath tub to soak
it overnight with a good quality bleach!!!.

Warm water with a bit of dish detergent and de-ionized water for a
rinse, will fix a lot of problems, particularly those that manifest
themselves in high humidity conditions due to crude on the circuit
boards.

BUT it takes a fair amount of electronics knowledge to know which
parts are not sealed and should stay dry, and a good drying technique
is a practical necessity. A home oven will work to warm and drive off
the moisture but a vacuum oven would be a better choice.

The folks that use isopropyl alcohol are essentially using a solvent
with the same characteristics as water. (most of it is ~30% water) It
just evaporates a lot faster than water so is easier to dry.
