Alcohol And Phones: A Safe Mix?

Alcohol can be used to clean your phone in certain situations, but it is not recommended. While alcohol can be effective at drying out water-damaged phones, it can also cause irreversible damage to screens, particularly LCD screens. This is because the liquid crystal screen is composed of multi-layer materials, including a layer of liquid crystal molecules that are very soluble in alcohol. If alcohol is poured directly onto the screen, it can flow into the gaps on the side of the screen, causing corrosion and leaving your phone screen mottled. Additionally, alcohol solutions will remove the oleophobic coating on your phone, which reduces oil absorption and fingerprints.

Is it safe to pour alcohol over my phone?

Alcohol can damage the oleophobic coating on your phone

Alcohol can be damaging to the oleophobic coating on your phone. This coating is a polymer layer that repels oils from your fingers, helping to keep your screen free of fingerprints and other marks. While it is possible to remove this coating, it is not recommended, as it can leave your screen looking blurry and hazy.

The oleophobic coating on smartphone screens is typically composed of organic compounds, which have very low resistance to alcohol. When wiped with alcohol, these coatings are likely to fall off. This is especially true for LCD screens, as both the polarizer and the liquid crystal molecules at the core of the screen are highly soluble in alcohol. Once the screen comes into contact with alcohol, these components will immediately begin to dissolve, causing the screen to become mottled.

It is important to note that even if your phone has a screen protector, alcohol can still damage the oleophobic coating. While screen protectors can help to slow down the natural wear and tear of the coating, they do not offer complete protection from the erosive effects of alcohol. Over time, the repeated use of alcohol-based cleaners will cause the coating to deteriorate faster.

If you need to disinfect your phone, it is recommended to use a soft cloth dipped in alcohol rather than pouring alcohol directly onto the screen. This will help prevent the alcohol from seeping into the sides of the screen and causing damage. Additionally, it is advised to reserve alcohol wipes for occasional deep cleaning, as frequent use can accelerate the breakdown of the oleophobic coating.

There are alternative methods to cleaning your phone screen without causing damage to the oleophobic coating. For example, you can use a lint-free or microfiber cloth dampened with water to gently wipe down your screen. If you're looking for a deeper clean, you can also purchase phone disinfecting products that are designed to protect the coating, such as PhoneSoap, HomeSoap, or PhoneSoap Shine.

It may not effectively disinfect your phone

While some sources claim that using alcohol to clean your phone is safe, there are several reasons why it may not be an effective method for disinfecting your device. Firstly, alcohol can cause irreversible damage to your phone screen, especially LCD screens. The liquid crystal molecules in LCD screens are highly soluble in alcohol, and once corroded, they will dissolve immediately, causing the screen to become mottled and blurry. Therefore, it is recommended to avoid pouring or spraying alcohol directly onto the screen.

Secondly, alcohol-based solutions can remove the oleophobic coating on your phone screen, which is designed to reduce oil adsorption and ease fingerprints. Without this coating, your screen may become more susceptible to oil stains and fingerprints, defeating the purpose of cleaning it in the first place. Additionally, the aggressive compounds in alcohol-based cleaners can leave your screen vulnerable to scratches or other types of damage.

Furthermore, alcohol may not effectively disinfect all the crevices and gaps in your phone, especially if you use a protective case. The Association for Professionals in Infection Control (APIC) has deemed ethyl alcohol and isopropyl alcohol ineffective in disinfecting because they lack sporicidal activity and cannot penetrate protein-rich materials. This means that bacteria and viruses may remain on your phone even after cleaning with alcohol.

While alcohol can be effective in drying out water-damaged phones, it is not recommended as a regular cleaning or disinfecting agent. There are specific products available, such as PhoneSoap, that are designed to effectively kill bacteria on your phone without causing damage to the screen or coatings. These products utilize UV-C lights to achieve a higher level of disinfection than alcohol wipes. Therefore, it is advisable to follow the recommendations of manufacturers and use alternative methods or products specifically designed for disinfecting electronic devices.

It can damage the LCD screen

Pouring alcohol over your phone can damage the LCD screen in several ways. Firstly, the liquid crystal screen is composed of multi-layer materials, with a layer of liquid crystal molecules sandwiched between two polarizers. Both the polarizer and the liquid crystal molecules are highly soluble in alcohol. Therefore, when exposed to alcohol, they will dissolve immediately, causing the screen to become mottled and damaged beyond repair.

Secondly, the surface of the glass covering the LCD screen is coated with a special organic film, often an oleophobic film, which reduces oil absorption and fingerprints. This coating has low resistance to alcohol and can easily be wiped off or eroded by alcohol, causing the display to become blurry. The sides of the LCD screen are particularly vulnerable to alcohol penetration, which can occur during the wiping process, further damaging the screen.

Additionally, alcohol-based solutions can negatively impact the oleophobic coating on the screen. This coating helps to repel oil and keep the screen cleaner for longer. Alcohol wipes or solutions will quickly shred or remove this coating, making the screen more susceptible to oil stains and fingerprints. As a result, the screen may become less smooth and start to collect more fingerprints over time.

It is worth noting that modern LCD screens, especially touch screens, are not as fragile as older versions. However, it is still recommended to avoid using alcohol for cleaning or disinfecting your phone. Instead, gently wiping the screen with a soft, alcohol-dipped cloth or using specific LCD screen cleaners is a safer option to maintain the integrity of your phone's LCD screen.

It can cause irreversible damage to the phone

Pouring alcohol over your phone can cause irreversible damage to the device. While it may be effective in drying out any water-based liquid inside the phone, alcohol can also cause serious damage to the screen, especially LCD screens. The liquid crystal screen is composed of multi-layer materials, including a layer of liquid crystal molecules sandwiched between two polarizers. Both the polarizer and the liquid crystal molecules are highly soluble in alcohol and can dissolve immediately if exposed, causing the screen to become mottled and blurry.

The sides of LCD screens are particularly vulnerable to alcohol penetration, as the liquid can find its way into the gaps on the side of the screen during cleaning. This can result in the alcohol seeping into the internal components of the phone, causing damage that may not be immediately apparent. Additionally, alcohol can remove the oleophobic coating on the screen, which is designed to reduce oil absorption and ease fingerprint smudges.

Furthermore, alcohol is not a comprehensive disinfectant for phones. It is ineffective against protein-rich materials, which are commonly found in the crevices of phones, especially those with cases. The Association for Professionals in Infection Control (APIC) has deemed ethyl alcohol and isopropyl alcohol inadequate for disinfection due to their lack of sporicidal activity. While alcohol can kill some bacteria, it is not as effective as other methods, such as UV-C light, which can kill 99.99% of bacteria.

It is worth noting that some people have successfully used alcohol to dry out their phones without apparent issues. However, this may be because the phone was already physically damaged by water, and the alcohol merely removed any remaining water-based liquid. In any case, it is not recommended to pour alcohol directly onto your phone, and there are safer alternatives available for cleaning and disinfecting your device.

It can be used to dry out a water-damaged phone

Pouring alcohol over your phone can be dangerous, and it is not recommended. However, in the case of water damage, some people have reported success in using alcohol to dry out their phones.

If your phone has been damaged by water, one option is to submerge it in 99% isopropyl alcohol, which can displace the water and accelerate evaporation. This method has been used to treat flooding in underwater cameras for many years. The high concentration of alcohol binds to the water, preventing it from corroding the metal or electronics. It is important to first remove the battery and open up the phone to dry any excess water. The phone can then be submerged in alcohol for 1-2 hours before being dried with a hairdryer and placed in a desiccant or rice overnight.

However, this method is not without its risks. Isopropyl alcohol can damage the glue that binds the screen to the glass, and it may not be suitable for all phone components. It is also important to avoid using heat sources like hairdryers, as they can cause more harm than good by pushing moisture deeper into the phone's components.

There are alternative methods to drying a water-damaged phone, such as using silica gel or vacuum sealing, which can be more effective and safer. Placing the phone in a sealed bag with silica gel or rice can help to absorb moisture and accelerate the drying process. Another option is to seal the phone in a vacuum-sealed bag, creating a low-pressure environment that encourages water to evaporate more quickly. On a sunny day, direct sunlight can also help to dry out a water-damaged phone, but it is important to avoid overheating the device.

Overall, while alcohol can be used to dry out a water-damaged phone, it is not recommended due to the potential risks involved. It is always best to seek professional assistance when dealing with water-damaged phones to ensure that the issue is properly addressed and to prevent further damage.
