Use heat and quality flux to burn accumulated crap under BGA chips.
For visible corrosion, scrub with toothbrush and alcohol.
Pay atention, do not knock off components and rebuild any affected trace.
Flux doesn't clean, it should be cleaned after all; with IPA, or ultrasonic bath.
I said the flux serves to burn the crap caused by liquid spill.
180 degrees is good enough.
I talk about board temp; hot air station will be set to 350-450; depending of air flow and distance to board.
