Take the phone to a professional water damage repair service

If DIY drying fails or the phone was submerged in saltwater, chlorinated water, or sugary liquids, a professional repair shop with water damage experience is the best option. These liquids leave corrosive residue that passive drying cannot address.

What Professionals Do

1. Disassemble the phone completely to access all internal components.
2. Clean circuit boards using isopropyl alcohol baths and ultrasonic cleaners to remove corrosion and mineral deposits.
3. Dry and inspect each component before reassembling and testing.

Tips

• Act quickly -- corrosion begins within hours of exposure and worsens over days.
• Ask for a diagnostic quote before authorizing repair. Water damage work often has a lower success rate and may not include a warranty.
• Avoid mail-in services for water damage; the delay allows corrosion to spread. Seek a local shop that can begin work the same day.
• Back up data immediately if the phone powers on after repair, as long-term reliability may be reduced.
