These instructions will do it. The most important aspect to have
in mind is do _not_ turn on the device before cleaning.

Yep. If available, a cleaning bath with demineralized water would help
to remove and limit the damage from minerals present in drinkable water.
Do not use standard "distilled" water you can't trust. It can cause even
more damage. That's when isopropyl alcohol comes... But I wouldn't use
a haird dryer for three reasons:
- the alcohol, being alcohol, is flammable. Bad thing to use an electric
heat source near, IMO.
- if a person isn't careful enough, additional heat can damage components.
- anyway, it gonna evaporate in a couple minutes...

Agreed. Something like coca-cola can do much more devastation...

Hey, but they use a highly demineralized water to clean the boards.
The kind that passes through a reverse osmosis filter 3 or 4 times
before becoming ready to use.
