If your iPhone 4 has been damaged by water, it's important to act quickly to try and minimise the harm. The first step is to turn off the device to prevent short circuits and then remove it from its case and any water source. You can then try to dry your iPhone by placing it in a sealed container with silica gel packets for 24-48 hours. It's important to avoid using a hairdryer or other heat sources as this can damage the internal components. If your iPhone still doesn't work after drying, you can try cleaning the corrosion on the internal parts with isopropyl alcohol. This step should be done with caution as it could wear down protective coatings.

What You'll Learn
Remove the iPhone from water and power it down
If your iPhone has been submerged in water, it is important to act quickly to minimise damage. The first step is to remove the iPhone from the water source as soon as possible. Do not try to turn it on; if it is still on, turn it off immediately to prevent short circuits and further damage.
Next, you should remove any cases or covers from the phone. You can gently wipe down the exterior with a soft, dry, absorbent cloth. Then, open the SIM card tray and remove the SIM card. This allows water trapped inside to escape.
It is important to note that you should not use a hairdryer or other heat sources to dry your phone, as the heat can damage its sensitive internal components. Instead, place the iPhone in a warm, dry, and well-ventilated location. You can prop it up on a cloth or paper towel so that the ports face downwards to encourage water drainage.
Resist the urge to turn on the phone right away. It is recommended to wait at least 24 to 48 hours to let it dry thoroughly before turning it back on.

Wipe the LCD screen with isopropyl alcohol
To wipe the LCD screen with isopropyl alcohol, you will need a non-dust cleaning cloth, such as a microfiber cloth, and isopropyl alcohol. Microfiber cloths are extremely soft and good at attracting dust. You can buy a pack of microfiber cloths so that you always have a clean one ready, as using a dirty one may transfer dirt and grime onto your screen. Avoid using paper towels, as these can scratch the LCD screen.
You should also be mindful of the type of isopropyl alcohol you use. While some sources recommend using 100% isopropyl alcohol, others advise against it, as it may harm plastic. A 50/50 combination with distilled water will dissolve fingerprint oil and other marking agents and evaporate quickly. It is important to note that you should not use tap water, as it can leave mineral spots and streaks on your screen.
When you are ready to wipe the LCD screen, do not spray the liquid directly onto the screen. Instead, spray the cloth with the isopropyl alcohol and distilled water mixture, or use a slightly moistened cloth. Gently wipe the screen in a counter-clockwise, or other consistent motion, applying even pressure to the cloth. Avoid buffing the screen or using excessive pressure, as you do not want to work any particles into the surface of the screen.

Let the iPhone air dry
If your iPhone has been damaged by water, it's important to act quickly to prevent further damage. Turn off your iPhone immediately to prevent short circuits. Then, remove any cases or covers and take out the SIM card tray to let the water flow out.
Next, you'll want to let your iPhone air dry. Place your iPhone in a warm, dry, and well-ventilated location. Do not use a hairdryer or other heat sources, as the heat can damage the internal components. Instead, let your iPhone air dry naturally for at least 24 to 48 hours. You can prop it up on a cloth or paper towel so that the ports face downwards to encourage water drainage.
Resist the urge to turn on your phone during this drying period. The longer you can wait, the greater the chance of recovery. Once your iPhone is completely dry inside and out, you can try powering it on.
If your iPhone shows signs of water damage or doesn't turn on after drying, it's best to consult an authorized Apple technician or a reputable repair shop. They can properly diagnose and repair any internal damage. Remember, acting quickly and correctly after a water incident can significantly improve the chances of saving your iPhone.

Check for corrosion and clean with alcohol
If your iPhone 4 has been damaged by water, it is important to act quickly to prevent corrosion. Corrosion is the gradual breakdown of material, usually metal, due to a chemical reaction with its environment. In the case of electronic devices, corrosion occurs when metal comes into contact with water and oxygen, forming iron oxide or rust.
To check for corrosion, you will need to disassemble your iPhone and inspect the internal components for any signs of damage. Start by removing the display and battery, as well as the SIM card and tray. Use a mobile phone opening tool to assist in disassembly and inspect the liquid contact indicator (LCI) in the SIM card slot or other locations specific to your iPhone model. A red indicator means that water damage has occurred.
If you find corrosion on any of the internal parts, you can attempt to clean it with alcohol. Isopropyl alcohol, also known as IPA, is commonly used for this purpose. It is important to use a high concentration of IPA, preferably 90% or higher, as the lower concentrations found in most stores may contain water, which could further damage your phone. You can apply the IPA with a toothbrush to scrub away corrosion, or use cotton swabs for more precise cleaning. Be sure to let the IPA evaporate completely before proceeding.
Alternatively, you can use medical alcohol (isopropyl alcohol) to clean the corrosion. Moisten a non-dust cleaning cloth with the alcohol and gently wipe down the affected areas. Again, allow the alcohol to fully evaporate before proceeding.
Once you have cleaned the corrosion and ensured that all components are completely dry, you can reassemble your iPhone and power it back on. It is important to note that there is no guaranteed way to fix a water-damaged device, and professional repair may be required if problems persist.

Reassemble the iPhone
Once you are sure that all the iPhone components are completely dry, you can start reassembling your iPhone. This process should be done in the reverse order that you took the parts out.
Firstly, replace all of the connectors and reinsert the screws. Make sure you are gentle and careful during this process, as force can cause further damage. Once all the parts are back in place, you can reinsert the battery. Again, be very careful during this step, as batteries contain hazardous chemicals and can cause injury if mishandled.
After replacing the battery, you can close the iPhone by fixing the back cover in place. Ensure that all the screws are tightened securely. Once the iPhone is physically reassembled, you can attempt to power it on. If the phone does not turn on, the damage may be more severe, and you may need to consult a professional repair service.

Frequently asked questions
Each iPhone has a small indicator that tells repair technicians that the phone has received water damage. The indicator is a piece of plastic that turns red when it comes in contact with water. For an iPhone 4, look for this indicator in the charging port or in the headphone jack.
If your iPhone 4 has been damaged by water, you can use 99% isopropyl alcohol to clean corrosion from internal parts. First, disassemble the iPhone and remove the display and battery. Then, use a non-dust cleaning cloth slightly moistened with isopropyl alcohol to wipe down the internal parts. Be careful to avoid the microphone and speaker. Finally, wait for the phone to dry completely before reassembling it.
If your iPhone 4 has been exposed to water, you should quickly remove it from the water source and power it down. Then, remove any cases or covers, and open the SIM card tray to let the water flow out. You can then place the phone in a sealed container with silica gel packets for 24-48 hours to absorb any remaining moisture. Do not use rice, as it can leave a residue and is less effective at absorbing moisture.
