Water on its own it’s not the big problem for electronics. Contrary to common belief, it would hardly damage electronics if it was ultra pure demineralized. Tap water and liquids in general contain minerals that are conductive, usually about 200/500mg per liter, sea water goes from 1800 to 3400mg/l. What one achieves with rice (silica gel too) is to accelerate drying and mineral concentration on electronic components, where power finds new paths to flow around, created by minerals. Unless electronics are properly decontaminated professionally, the earlier the better, it’s usually a matter of weeks or months at the best before they stop working. As you have experienced yourself, with time things are already getting worse. Enjoy rice for a good meal, but forget it to recover liquid damage, it useless at best.
