It's very fast, thorough and doesn't require much effort. Pretty self-explanatory:
1. Remove all electrical components that you care about.
2. Use a spray bottle to cover everything with a weak soap solution. A bit of dishwashing soap works pretty good.
3. Hose everything down (with tank water ideally, not town water).
4. Obviously let it all dry out completely before re-using.
And yes, that intake fan is definitely getting a bath. It was already dead.
