Salt Water in Phone Speaker: Emergency Action Protocol

Dropped phone in the ocean or salt water? CRITICAL emergency steps: how to rinse, eject salt water, and stop salt crystal corrosion.

Start audio tests at low volume; stop for distortion. Tones cannot guarantee removal of water or repair internal damage. Do not charge a wet device.

When fresh water dries, it evaporates cleanly. When salt water dries, salt crystals crystallize across the speaker diaphragm. These sharp microscopic crystals puncture delicate voice coil surrounds and corrode copper wires within 24 to 48 hours.

Rinsing with fresh water first, followed immediately by acoustic ejection, is the only proven method to save water-resistant phones dropped in the ocean.
