How to Clean Your Phone

What you need
- A soft, lint-free cloth: Use this to wipe down your phone without scratching its surfaces. Apple suggests a lens cloth, and Samsung links to microfiber cleaning cloths.
- Warm, soapy water: Just a few drops of dish soap in some water will do it. We like Seventh Generation Dish Liquid.
- 70% isopropyl alcohol wipe: Apple, Samsung, and Google all recommend using isopropyl alcohol–based cleaning wipes on their devices. Apple also says you can use 75% ethyl alcohol wipes or Clorox Disinfecting Wipes. Samsung additionally suggests 50- to 80-ppm hypochlorous acid–based solutions.
- A wooden toothpick: We recommend using a toothpick to clean out your phone’s ports. Metal can damage the internals, and cotton swabs would leave behind more debris.
How long will this take to clean?
Most of the time it will take only a few seconds to wipe down your phone. Prying lint out of your charging port may take a couple of minutes, depending on how much is in there. Wipe down your phone whenever you notice a smudge-filled screen or you use it in a germy environment where you think it could use a cleaning.
Unplug and turn off your phone
When you’re cleaning your phone, there’s only a small chance of doing any damage to its internals. But it’s best to make sure your phone is fully powered off and disconnected from power before you wipe it down.
Gently wipe with a cloth
Before you use any cleaning solutions, give your phone a wipedown with your soft cleaning cloth. This should remove any fingerprints or smudges. If there’s any dust or other materials between your cloth and your phone, pressing too hard could potentially cause scratches, so don’t overdo it.
Wash with warm, soapy water
If there are still marks, try using your microfiber cloth damp with warm, soapy water. This should get rid of any stains that are going to come out.
Disinfect
A simple swipe with your favorite disinfectant wipe—alcohol-based, or Clorox wipes—will kill most germs on your phone’s surface.
Remove lint and dust from the port
If you’ve noticed your phone struggling to charge when it’s plugged in, lint and dust jammed in the charging port could be to blame. A wooden toothpick is an ideal tool to use in this case. It’s small enough to fish out any lint, but it shouldn’t scratch or otherwise damage the metal contacts, which could cause bigger issues.
None of the three phone manufacturers we researched provide any guidance on this kind of cleaning, but we’ve always had success with a gentle touch. As always, there’s some risk when you’re doing anything to your phone that’s not recommended by the manufacturer.
What not to do
Apple, Samsung, and Google all recommend against spraying cleaner directly on your phone. Instead, get the cleaning cloth wet, and use it to wipe down your device. They all also specifically say not to use compressed air or bleach.
