Accidentally dropping an iPhone into fuel, such as gasoline or diesel, is a serious issue. Unlike water damage, fuel can cause more severe internal corrosion and damage to the screen, ports, and battery. Handling the situation correctly is crucial to prevent permanent failure.
Immediate Steps to Take
If your iPhone falls into fuel, remove it as quickly as possible. Keeping the device submerged increases the risk of damage to internal components. Do not attempt to turn it on or charge it, as this can cause short circuits. Instead, move to a well-ventilated area, as fuel fumes can be hazardous.
Begin by wiping the device with a clean, dry cloth to remove excess fuel. Avoid using paper towels, as they can leave fibers behind. If the iPhone has a protective case, remove it immediately to prevent fuel from getting trapped inside. Use isopropyl alcohol with a high concentration, preferably to clean the surface. This helps dissolve fuel residues and reduces the chances of chemical corrosion.
Drying and Internal Cleaning

After cleaning the outer surface, the next step is to address potential internal damage. Unlike water, fuel leaves an oily residue that does not evaporate easily. Simply leaving the device to dry will not be sufficient. Do not use a hairdryer or place the iPhone in rice, as these methods are ineffective for fuel exposure.
Disassembling the iPhone is the best way to ensure proper cleaning, but this should only be attempted if you have technical experience. If you choose to proceed, use a to remove the screws and open the device carefully. Clean the internal components, such as the battery and logic board, with isopropyl alcohol and a soft brush.
Professional Repair Options
If you are unable to clean the device thoroughly or if it does not turn on after drying, professional repair is necessary. Fuel exposure can damage connectors and corrode delicate circuits, requiring expert intervention. Contacting an Apple Authorized Service Provider is the safest option. Apple does not cover liquid damage under warranty, but they can assess the extent of the damage and suggest possible repairs or replacements.
For those looking for third-party repair services, uBreakiFix offers specialized cleaning and diagnostic services for liquid-damaged devices. They can disassemble the iPhone, clean fuel residues, and replace affected components. Choosing a professional repair service ensures that the phone is restored with proper tools and expertise.
Preventing Future Incidents
To avoid similar situations in the future, always use a high-quality waterproof case when working around fuel. Keep your phone secured in a pocket or bag instead of placing it on surfaces where it may slip. If working in an environment where fuel exposure is possible, consider using a secondary device that is designed to withstand extreme conditions.
While an iPhone can sometimes survive water exposure, fuel is far more damaging. Acting quickly and following proper cleaning steps can improve the chances of recovery. However, if the device fails to function correctly after cleaning, professional repair is the best course of action.
