Cleaning your screen with alcohol may seem like a good idea, but it can actually damage your device. Alcohol can seep into the backlight layers of your screen, stripping away coatings and causing permanent clouding. If you have used alcohol to clean your screen, you may need to replace it. To avoid further damage, it is recommended to use a microfiber cloth, either dry or dampened with water, to gently wipe away any smudges or fingerprints. There are also screen cleaners specifically designed for electronic devices that can be purchased at most electronics shops.

What You'll Learn
Avoid alcohol on screens—use a microfiber cloth instead
Using alcohol to clean your screen may seem like a good idea, but it can cause more harm than good. Alcohol can damage the coatings on your screen, leading to costly repairs. For example, using alcohol on a Retina MacBook Pro can damage the oleophobic coating, designed to prevent fingerprint smudges. As a result, the entire assembly must be replaced at a cost of US$500-650.
Instead of alcohol, opt for a microfiber cloth to clean your screens. Microfiber cloths are inexpensive and can be washed and reused. They are effective at removing dust, debris, and fingerprints from screens. When using a microfiber cloth, be sure to wipe in straight vertical moves, from top to bottom and left to right, rather than circular motions. Avoid pressing too hard on the screen, especially if it is an LCD or OLED display, as this can cause damage.
If you're dealing with stubborn spots or hand oil residue on your screen, you can dampen the microfiber cloth with distilled water or a mixture of warm water and a mild soap. Avoid using too much liquid, as you don't want it dripping wet. For laptops, you can also remove the battery before beginning to wipe down the screen and the rest of the device.
While microfiber cloths are a great option, not all are created equal. Some may be too small or poorly constructed, with logos that can scratch surfaces. Look for a cloth that is soft, smooth, and has just enough friction to wipe away dirt and grease without causing damage.
In summary, avoid using alcohol on your screens and stick to microfiber cloths instead. With proper care and maintenance, your screens will stay clean and clear.

Use a 50/50 mix of water and isopropyl alcohol for tough stains
If you have accidentally cleaned your screen with undiluted alcohol, you may be able to fix it by using a 50/50 mix of water and isopropyl alcohol. This solution is recommended by some manufacturers for tackling tough stains.
Firstly, power off your device and unplug it. Then, dip a microfiber cloth into the solution—do not spray liquid directly onto the screen. Gently wipe the affected areas in a circular motion until the marks disappear. Make sure not to apply excessive pressure to prevent damaging the screen.
It is important to note that you should not use excessive alcohol, as it can harm the screen's coating. Always use the solution sparingly and with caution.
Some manufacturers, such as Apple, recommend using cleaners with isopropyl alcohol for their products. However, it is important to follow the manufacturer's guidelines for your specific device.

Apple recommends isopropyl alcohol—not ethanol
Apple users have historically been advised to use only a microfiber cloth slightly dampened with water to clean their device screens. However, Apple now recommends using cleaners with isopropyl alcohol, specifically a 70-percent isopropyl alcohol (IPA) solution, to clean hard-to-remove smudges or fingerprints on the display or exterior of your Mac.
Isopropyl alcohol is thought to break down the proteins and DNA that viruses, bacteria, and other germs need to survive. It is also thought to dissolve the fat and protein that make up their protective outer membrane.
Ethanol, or ethyl alcohol, is another type of alcohol that can be effective at killing germs. It kills germs in a similar way to isopropyl alcohol, by breaking down their essential fats and proteins. While ethanol is considered superior to isopropyl alcohol by the World Health Organization (WHO), it may take longer to kill certain bacteria. For example, a 50 percent ethanol solution needs 15 minutes to kill E. coli bacteria, while several common bacteria can be killed in less than two minutes with 70 percent ethanol.
Although both types of alcohol can be effective cleaners, it is important to follow Apple's recommendations and use isopropyl alcohol when cleaning Apple products. The reason for this is that the Retina display on MacBooks is one sealed assembly, and if the coating is damaged, the entire assembly must be replaced, which can be costly.

Alcohol can strip coatings, causing permanent clouding
While it may be tempting to use alcohol to clean your screen, it is important to exercise caution. Alcohol can indeed damage screens by stripping their protective coatings, causing permanent clouding and malfunction. This is because alcohol acts as a solvent, degrading the coatings over time and causing the crystals to lose their effectiveness.
For example, many LCD screens have a reflective coating that can be stripped away by rubbing alcohol, allowing moisture to seep in and causing damage that may void the manufacturer's warranty. Similarly, using alcohol to clean glasses can cause the anti-reflective coating to deteriorate, affecting vision and causing visual discomfort. Over time, the lenses may become cloudy, hindering vision and reducing sharpness.
The concentration of alcohol is also critical. Pure isopropyl alcohol (90% or higher) is too harsh for most LCD screens and should be avoided. Lower concentrations (70% or less) are safer for screens but may be less effective at removing stubborn stains. A mixture of 50% isopropyl alcohol and 50% water is generally recommended to minimize potential damage while maintaining cleaning effectiveness. However, even at lower concentrations, alcohol can still damage the protective coatings on some screens.
To avoid damage, it is recommended to use a microfiber cloth to gently wipe the screen with a specialized cleaning solution or a mixture of equal parts distilled water and white vinegar. Always apply the solution to the cloth and not directly to the screen, and be sure to follow the manufacturer's instructions carefully.
In summary, alcohol can strip coatings and cause permanent clouding on screens, so it is important to use alternative cleaning methods to avoid damage and maintain optimal screen performance.

Some screens can withstand alcohol—like AG Neovo's NeoV series
Cleaning your screen with alcohol can be risky, as it can damage the anti-reflective or anti-glare coatings, causing permanent clouding. Apple, for example, previously recommended only using a microfiber cloth slightly dampened with water, and not solvents or alcohol. However, Apple now suggests using cleaners with isopropyl alcohol. It is important to follow manufacturer recommendations, as repair costs for screens can be high.
Some screens, however, can withstand alcohol, like AG Neovo's NeoV series. The NeoV monitor with optical hard glass passes the alcohol, acid, and alkali resistance tests, ensuring that alcohol or household disinfectants will not damage the coating on the glass. The NeoV monitor is designed for demanding environmental applications and can be cleaned safely with alcohol. Its sealed design also prevents any splashed liquid from getting on the screen or flooding into the panel. The NeoV monitor with optical hard glass screen can withstand ammonia, alcohol, bleach, and cleaning products with high pH levels.
The NeoV monitor is ideal for medical professionals who need to sanitize their screens easily. It is also perfect for multiple healthcare applications, as it is IEC/EN 60601-1 certified. The NeoV monitor is designed to bring users supreme image performance, LCD panel protection, and easy maintenance. The optical hard glass screen is specially formulated to enhance image quality and protect the LCD panel from any incidental damage.
The NeoV monitor also provides unparalleled resistance to scratches, with a coated surface that reaches 9H, the highest grade on the pencil hardness scale. It can protect LCD screens from dust and water and prolong the monitor's life performance in dusty and damp environments. The NeoV monitor's multi-layer coating can decrease glare and reflection, resulting in an 89.3% visual improvement. With a high 98.60% transmittance rate, the monitor provides nearly perfect brightness.
