This guide compares official Apple and Samsung instructions. Both emphasize avoiding moisture in openings and not spraying liquid directly on the phone. Do not generalize one disinfectant concentration to every model. The cover is a reference photo of an iPhone 15 Pro, not a cleaning demonstration.

1. Unplug charging cables and accessories, power the phone off and remove the case if its instructions permit separate cleaning.
2. Use a clean soft, lint-free microfiber cloth to gently wipe dust and smudges from the screen and back. Avoid paper towels and abrasives.
3. For stubborn grime, slightly dampen a corner of the cloth with water; first follow the instructions for your exact iPhone or Galaxy model.
4. Never spray water, cleaner or disinfectant directly on the phone. Keep liquid away from charging ports, speakers, buttons and openings, and avoid compressed air.
5. For disinfection, Apple permits 70% isopropyl-alcohol or 75% ethyl-alcohol wipes on specified iPhone exterior surfaces. Samsung describes its own permitted agents and concentrations, applied to a cloth. Check your model's guidance rather than treating the methods as interchangeable; avoid bleach and hydrogen peroxide.
6. Gently finish wiping and confirm the device and openings are dry before using or charging it. Clean the case separately according to its material, and seek service if liquid enters the device.
