What is corrosion, and what does it do to your phone?

Corrosion is one of the reasons why electronics and water just don’t mix. It is the gradual breakdown of material, typically metal, due to a chemical reaction between the material and its environment.

The most encountered form of corrosion happens when metal (line your phone’s components) is combined with oxygen and water. It results in the formation of iron oxide, more commonly called rust.

Depending on the severity of water damage and humidity levels, corrosion may occur a few hours or even days after the encounter. Other factors like the duration of your phone submerged in water and how it is made significantly affect the time frame of damage occurrence.


Removing Corrosion From Your Phone After Water Damage

Cleaning corroded electronics, like your phone, requires utmost care. Not only can you worsen the damage, but you can also create harm to yourself.

It is advisable that average customers should not attempt repairing devices without professional assistance. However, here are a few tips that may be helpful in dealing with corrosion on water damaged devices:


Step #1. Remove any batteries, power supplies, and power connectors first

In order to prevent short circuits and any harm to you, you must remove any batteries and power supplies, and connectors first. Doing this will also help you discover more connectors that also got corroded.


Step #2. Inspect your phone for any white or green “crusty” areas

Take a closer look at your device and spot any white or green crusty areas on charging ports, battery connectors, logic boards, circuit boards, SIM card connectors, and other major metal connectors in your device.


Step #3. Clean the corrosion away

Prepare cotton swabs saturated with a cleaning solution like isopropyl alcohol, vinegar, or baking soda and water. Use them to gently apply the solution onto the affected areas.

Wipe the corrosion back and forth until it is removed. If the damage looks like it needs more, you can try leaving an amount of the solution in the area for some time before wiping it away later.


Step #4. Dry your phone

The last step is to dry your phone using a soft cloth or a hairdryer in a cool setting, as you should never use heat to dry your device. Make sure that it is completely dry before putting the batteries and attempting to turn it on to avoid further damage.
