Compass not working (orientation also) after water damage

Hello

Yesterday my phone was taken out in heavy rain and a fair amount found its way in.

After taking it apart, and loosening some contacts, I found water under the screen connectors, battery connectors, etc, so I dried them out with QTips covered in isopropyl, and using a hairdryer.

At this point, it works fine, however the compass no longer functions. I took it all apart, cleaned some contacts with isopropyl but compass is stuck on 4 degrees and rotation is stuck on landscape. The battery drains suspiciously quick now. This does all point to a short somewhere? Based on that I am hoping that dunking the logic board in isopropyl may help but that would only be possible once I got home, which is in 6 hours from now.... that would make it a full 24 hours since it being submerged so I'm not quite sure about the chances of survival.

It has been on since then too so I fear I may have made it worse...

Any ideas as to what I can do? Could it be the gyroscope chip that is still moist, or damage to the M8 coprocessor

Many thanks
