Similarly, when cleaning TV screens, hydrogen peroxide is typically advised against. The chemical composition of hydrogen peroxide can cause serious damage to TV screens, which are delicate and easily affected by the wrong products or handling. While it may be tempting to use hydrogen peroxide to eliminate unsightly streaks and smudges, it is generally safer to stick to distilled water or a non-ammonia cleaner sprayed onto a microfiber cloth.

The potential for damage from hydrogen peroxide is not limited to screens alone. When cleaning any electronic device with hydrogen peroxide, it is crucial to exercise caution. It is recommended to dilute hydrogen peroxide with water at a ratio of 1:9 or 1:10 before use, and even then, some manufacturers advise against it. Before applying any cleaning solution, it is essential to power off and unplug the device. Additionally, after cleaning with hydrogen peroxide, it is vital to thoroughly rinse and wipe the device with a damp cloth to remove all residue, followed by allowing sufficient drying time before use.

In summary, while hydrogen peroxide can be useful for disinfecting and cleaning certain surfaces, it is generally not recommended for cleaning screens due to the risk of damage. It is always advisable to refer to the manufacturer's guidelines and use specific products designed for cleaning screens and electronic devices.

Alcohol can remove fingerprints

Apple recommends using a soft, slightly damp, lint-free cloth to wipe down screens and devices to remove fingerprints. However, for hard-to-remove smudges or fingerprints on screens, a cloth moistened with a 70% isopropyl alcohol (IPA) solution can be used. This method is recommended for MacBooks, MacBook Pros, MacBook Airs, and iPhones.

For iPhone users, it is important to unplug all cables and turn off the device before cleaning. Additionally, it is crucial to avoid getting moisture into any openings. Apple also advises against using window or household cleaners, compressed air, aerosol sprays, solvents, ammonia, abrasives, or cleaners containing hydrogen peroxide, as these could damage the device.

Similarly, for MacBook users, it is recommended to shut down the computer and unplug the power adapter before cleaning. Again, it is vital to avoid getting moisture into any openings and to refrain from spraying liquid directly onto the computer. Solvents, abrasives, and cleaners containing hydrogen peroxide should be avoided as they may damage the finish.

While hydrogen peroxide can be used to clean electronic devices, it requires careful handling and dilution. It is generally recommended to dilute hydrogen peroxide with water at a ratio of 1:9 or 1:10, ensuring that it is well-mixed before use. Gloves and safety glasses are also advised when handling this solution, and it is crucial to avoid contact with the skin. After cleaning with hydrogen peroxide, it is essential to rinse the device thoroughly and wipe it down with a damp cloth to remove any residue.

In summary, while both alcohol and hydrogen peroxide can be used for cleaning screens, alcohol, specifically isopropyl alcohol, is generally recommended by manufacturers like Apple for removing fingerprints and hard-to-remove smudges. Hydrogen peroxide, while effective for disinfecting and cleaning other surfaces, requires more careful handling and dilution for use on electronic devices.

Dilute hydrogen peroxide for safety

Hydrogen peroxide is a highly reactive chemical available in several concentrations. Exposure to small amounts of household (3%) hydrogen peroxide usually only causes mild irritation. However, higher concentrations can cause burns, and in rare cases, life-threatening effects can occur when oxygen bubbles from hydrogen peroxide travel to the circulatory system and block blood flow to tissues. Therefore, it is always best to dilute hydrogen peroxide before using it to clean electronic devices.

Diluting hydrogen peroxide can make it safer to use and reduce the risk of irritation or burns. The ratio of hydrogen peroxide to water is typically recommended as 1:10 or 1:9, meaning for every one part of hydrogen peroxide, mix nine or ten parts of water. This dilution ratio will ensure that the hydrogen peroxide solution is safe and effective for cleaning screens and other electronic devices.

When diluting hydrogen peroxide, it is important to take the necessary safety precautions. Wear gloves to protect your skin and avoid direct contact with the solution. It is also recommended to work in a well-ventilated area and have a fire extinguisher nearby in case of any accidents.

After diluting the hydrogen peroxide, it can be applied to a soft, lint-free cloth or sprayed directly onto the screen or electronic device. Gently wipe the screen or device with the cloth, ensuring that no liquid gets into any openings or seams. Finally, use a damp cloth to remove any remaining residue and dry the surface thoroughly before turning the device back on.

By diluting hydrogen peroxide and following the necessary safety precautions, you can effectively and safely clean your screens and electronic devices without causing any damage or irritation.

Alcohol wipes are effective

For iPhone users, Apple suggests using a soft, slightly damp, lint-free cloth to wipe the screen. If there are fingerprints or oil stains on the screen, a small amount of rubbing alcohol can be placed on the cloth to help remove these marks. It is important to avoid using window cleaners, household cleaners, compressed air, aerosol sprays, solvents, ammonia, abrasives, or cleaners containing hydrogen peroxide, as these may damage the oleophobic coating on the screen.

Similarly, for MacBook and iMac users, Apple recommends using a damp, soft, lint-free cloth to clean the computer's exterior and screen. For hard-to-remove smudges or fingerprints on the display or exterior, a cloth moistened with a 70% isopropyl alcohol (IPA) solution can be used to gently wipe the surface. Again, it is crucial to avoid spraying liquid directly onto the computer and to ensure that no moisture gets into any openings.

Alcohol wipes are generally considered safer for cleaning screens than hydrogen peroxide solutions.
