Corrosion

Chemical destruction of your iPhone’s board after liquid exposure

Corrosion is the chemical destruction of copper traces, solder joints, and component pads on the iPhone logic board after liquid exposure. It appears as green, white, or grey deposits and continues spreading even after the liquid has dried and the phone appears to work normally. Singapore’s humidity accelerates corrosion significantly — a phone that seems fine after getting wet may fail days or weeks later.

Why It Matters For Your Repair

Corrosion caught early and treated with ultrasonic cleaning can often be fully resolved. Left for days or weeks, it destroys board traces permanently — leading to component failure that cannot be repaired. This is why bringing in a water-damaged iPhone immediately — even if it seems to work — is so important. The sooner it’s treated, the better the outcome.
