PhoneSoap 3

Dual-sided UV-C illumination and charging access make it a practical choice for routine phone sanitizing.

Not for: Tablets, oversized devices, or removing visible dirt; not a substitute for cleaning.

UV type. It must use germicidal UV-C, typically around 254 nm from mercury lamps or UV-C LEDs. UV-A or plain violet LEDs don't sanitize. Many cheap boxes use non-germicidal light that looks the same.
Enclosed chamber. Choose a closed box that shuts off when opened, with reflective interior walls. UV-C harms skin and eyes, and reflective walls reach the sides of the phone.
Chamber size. Confirm your largest phone fits with its case on. Big phones in rugged cases often don't fit compact boxes.
Realistic expectations. UV only reaches exposed surfaces. Shadowed areas and dirt stay untreated, so wipe first with 70 percent isopropyl alcohol, which phone makers allow. Dirt shields germs from UV.

Will UV-C damage my phone?

Normal enclosed sanitizing cycles are generally considered safe for phones. Repeated long exposure can yellow some clear plastic cases over time.
