id suggest running the device through a sonic wash if you have the tools. clean out any shorts from the corrosion. you can also use deoxidizing solution as well. (i prefer De-Oxit). if you dont have access to these tools, you should resort tohiring a technician that has invested in them. if you really dont want to do that, you can always use isopropyl (99%) and a clean toothbrush to scrub at the board. (gently but diligently) and hope it gets all the corrosion. id also suggest soaking the board in it for about 10 minutes before the scrub.
