Hi Leon,
Corroded as it may be, and it's hard to see the minute detail of it,
does the unit operate?
If so, clean and protect the unit as per the advice of Lewis earlier.
If not, with careful inspection with a magnifier, check all the circuit board tracks to see if the corrosion has caused any breaks or cracks etc.. Then if required repair these with a soldering iron, bits of wire, solder bridges (or circuit board foil).
On completion - a light brush with a tooth brush and alcohol or metho as already suggested is also a good idea, as well as a coating/spray of circuit board lacquer for protection. Perhaps also inspect the housing of the printed circuit board for any possible entry points or poor orientation resulting in some minute water / vapour entry which may have (barring some galavanic corrosion) otherwise given rise to the corrosion/damage.
Good luck
Best
