It’s generally safe to clean the back of your phone and the camera lenses with 70% isopropyl alcohol, but there are a few things to consider.
1. Back of the phone: Isopropyl alcohol (70%) can be used on the back of your phone, but you should avoid soaking the device. Instead, apply a small amount to a microfiber cloth, and gently wipe the surface. Avoid getting any liquid into the ports or openings.
2. Camera Lenses: Isopropyl alcohol can be used on the camera lenses, but you should be extra careful. The lens coating may get damaged if too much alcohol is applied or if it’s rubbed too harshly. It’s better to use a microfiber cloth slightly dampened with the alcohol to wipe the lens gently. Avoid direct spraying, as this can leave moisture behind.
Alternative to Isopropyl Alcohol: You can also use a lens cleaning solution made specifically for cameras or phones, which is often gentler and designed for delicate surfaces. A soft microfiber cloth is always the best tool for cleaning lenses to avoid scratches.
Harm: Over time, aggressive cleaning with alcohol may cause the protective coating on the lens to degrade, leading to diminished photo quality or surface marks. Always be gentle and avoid using excess liquid.
