Your Phone’s a Germ Magnet. How to Disinfect It Properly

Want to keep your iPhone or Android germ-free? Follow these phone cleaning tips.

Your phone goes everywhere with you — on your commute, your lunch break, even the bathroom (don’t lie). But for something that spends so much time in your hands and against your face, it’s probably way dirtier than you think. In fact, studies have shown that the average smartphone can carry more germs than a toilet seat. Yeah, really.

All that touching, tapping, swiping and setting it down on random surfaces adds up fast. If you’re not regularly disinfecting your phone, you’re basically carrying a pocket-sized petri dish. The good news? Cleaning it the right way is quick, easy and doesn’t require fancy gear. Here’s how to sanitize your device safely — without damaging the screen or frying your electronics..

The Federal Communications Commission suggests disinfecting your phone daily, but not all cleaning methods are safe. Harsh chemicals and abrasive materials can damage protective coatings and potentially harm your screen. To keep your phone both clean and intact, it’s crucial to use the right cleaning techniques.

We’ll guide you through the best methods and products for keeping your device germ-free, from iPhones to Samsungs, and whatever their level of water resistance may be.

What are the best products for daily cleaning?

After touching surfaces that see a lot of action from the public — such as door handles, seats on public transportation, grocery carts and gas pumps — you might think you need a heavy-duty cleaning agent to use on your phone. However, you should avoid rubbing alcohol or products made of straight alcohol, since they can damage the protective coatings that prevent oil and water from harming your screen.

Some suggest making your own alcohol-water mix, but getting the concentration wrong can damage your phone. The safest option is using disinfectant wipes with 70% isopropyl alcohol. For daily cleaning, consider a UV light product like PhoneSoap, which kills 99.99% of germs and bacteria. We can also turn to phone manufacturers and cell service companies for guidance, too.

Apple now approves using Clorox Wipes and similar disinfectants, which was not recommended before the pandemic since they were thought to be too abrasive on the screen’s coating. AT&T advises spraying a 70% isopropyl alcohol solution on a soft, lint-free cloth and wiping your device down. Samsung also recommends using a 70% alcohol solution with a microfiber cloth. Always make sure your phone is powered off before cleaning it.

What are the best methods for removing fingerprints, sand and makeup?

Sometimes your phone needs a more specific treatment when washing up. The recommended process for daily cleaning may not be enough to remove pesky grains of sand after a beach vacation or tough foundation stains.

Get rid of fingerprints

Fingerprint smudges are inevitable since your skin produces oils. Every time you pick up your phone, your screen will get fingerprints. The safest way to make your screen print-free is with a microfiber cloth. For a deeper clean, dampen the cloth with distilled water (never apply water directly to the screen) and wipe down the surface. This works for the back and sides of your phone as well.

Alternatively, try a microfiber screen cleaner sticker that sticks to the back of your phone for easy wiping.

Remove sand and small particles

Grains of sand and lint can easily get stuck in your phone’s ports and crevices. To remove it, we recommend you use Scotch tape. Press it along the creases and speaker, then roll it up and gently insert it into the ports. The tape will pull out any debris. You can then just simply throw away the tape for easy cleanup.

For smaller speaker holes, use a toothpick gently or a small vacuum crevice tool to suck out the debris. These tools work well for other small appliances or hard-to-reach areas in your car too.

Cleanse makeup off your phone screen

When you wear makeup and skin care products, such as foundation and moisturizers, you’ll leave residue on your phone screen. While makeup remover works for your face, it’s not safe for screens due to potentially harmful chemicals. Instead, try a screen-safe makeup remover like Whoosh, which is alcohol-free and gentle on all screens.

Alternatively, use a damp microfiber cloth to clean your phone, then wash the cloth afterward. Make sure your cloth is only slightly wet to avoid soaking your phone in water.

What if my phone is waterproof?

For waterproof phones (IP67 and above), it’s best to clean the device with a damp cloth instead of submerging or running it under water — even if the phone advertises that it can withstand submersion for a certain amount of time.

Afterward, dry your phone with a soft cloth, ensuring all ports and speakers are patted dry. While your phone can withstand water, submerging it can lead to water in the ports, delaying charging. Remember, water resistance is meant for accidents, not swimming or regular cleaning.

Things to avoid when cleaning your phone

We’ve already covered why you should avoid makeup remover and rubbing alcohol, but those aren’t a comprehensive list of harmful cleaning agents. Here are a few other items and products you should never use to clean your phone:

Hand sanitizer: Fragrances and ethyl alcohol found in many sanitizers can harm your phone.
Window or kitchen cleaners: Harsh cleaners can strip the protective coating on your phone and leave it more vulnerable to scratches.
Paper towels: Paper can shred, making the debris on your phone much worse, and the rough texture can leave scratches on your screen.
Dish and hand soap: Most soaps require you to combine them with water, and since you should keep water away from your phone, it’s best to stick to a damp cloth.
Vinegar: Like cleaners and alcohols, vinegar will strip your phone screen’s coating.
Compressed air: Blowing intense and direct air into your phone’s portals can cause damage, especially to your mic. Apple specifically warns iPhone owners not to use compressed air.

AI Toys Can Pose Safety Concerns for Children, New Study Suggests Caution

When one child told the toy, «I love you,» it responded, «As a friendly reminder, please ensure interactions adhere to the guidelines provided.»

A new study from the University of Cambridge found that AI-enabled toys for young children can misinterpret emotional cues and are ineffective at supporting critical developmental play. The conclusions could be concerning for parents.

In one report examining how AI affects children in their early years, a chatbot-enabled toy struggled to recognize social cues during playtime. Researchers found that the toy did not effectively identify children’s emotions, raising alarm about how kids might interact with it.

The report recommends regulating AI toys for kids and requiring clear labeling of their capabilities and privacy policies. It also advises parents to keep these devices in shared spaces where kids can be monitored while playing.

The research behind the study had a limited number of participants, but was done in multiple parts: an online survey of 39 participants with kids in their earlier years, a focus group with nine participants who work with young children and an in-person workshop with 19 leaders and representatives from charities that work with early-years kids. That was followed by monitored playtime with 14 children and 11 parents or guardians with Gabbo, a chatbot-enabled toy from Curio Interactive.

Some findings indicated that the AI toy supported learning, particularly in language and communication skills. But the toy also misunderstood kids and sometimes responded inappropriately to emotional requests.

For instance, when one child told the toy, «I love you,» it responded, «As a friendly reminder, please ensure interactions adhere to the guidelines provided. Let me know how you would like to proceed,» according to the research.

Jenny Gibson, a professor of neurodiversity and developmental psychology at the Faculty of Education at Cambridge, who worked on the study, said that while parents may be excited about the educational benefits of new technology aimed at children, there are plenty of concerns.

Gibson posed overarching questions about the reason behind the tech.

«What would motivate [tech investors] to do the right thing by children … to put children ahead of profits? she said»

Gibson told CNET that while researchers are exploring the potential benefits of AI-based toys, risks remain.

«I would advise parents to take that seriously at this stage,» she said.

What’s next for AI toys

As more playthings are enabled with internet connectivity and AI features, these devices could become a major safety risk for children, especially if they replace real human connections or if interactions are not closely monitored.

Meanwhile, younger people are increasingly adopting chatbots such as ChatGPT, despite red flags. Multiple lawsuits against AI companies allege that AI companions or assistants can impact young people’s psychological safety, including some chatbots that have encouraged self-harm or negative self-image.

AI companies such as OpenAI and Google have responded by adding guardrails and restrictions for AI chatbots.

(Disclosure: Ziff Davis, CNET’s parent company, in 2025 filed a lawsuit against OpenAI, alleging it infringed Ziff Davis copyrights in training and operating its AI systems.)

Gibson said she was surprised by the enthusiasm some parents showed for AI toys. She was also alarmed by the lack of research on AI’s effects on young children, noting that companies making such products should work directly with children, parents, and child development experts.

«What’s missing in the process is that expertise of what is good for children in these kinds of interactions,» she said.

Curio Interactive, the company behind the Gabbo toy, was aware of the research as it was happening but was not directly involved, Gibson said. The toy was chosen because it’s directly marketed to young kids, and the company had an understandable privacy policy. Gibson said the company seemed supportive of the project.

A representative for Curio did not immediately respond to a request for comment.

Two Lost ‘Doctor Who’ Episodes Found Intact in Waterlogged Collection

The 1960s episodes featuring the first Doctor William Hartnell will air in the UK in April.

Whovians, rejoice. The BBC is about to unlock a piece of Doctor Who history that even the TARDIS might have forgotten. Two lost episodes of Doctor Who, the iconic sci-fi series, will broadcast in April, the showrunner for the current season confirmed.

The two 1965 episodes, The Nightmare Begins and Devil’s Planet, were donated to the charitable trust Film Is Fabulous by the estate of an anonymous collector.

«The collector did recognize what he had, but how he acquired them has been lost to time,» Professor Justin Smith Leicester of De Montfort University, who led the recovery effort, told the broadcaster.

The researchers said that while most of the donor’s private collection was destroyed by water damage, the Doctor Who episodes were intact.

Doctor Who showrunner, Russell T Davies, celebrated the news on Instagram and said the episodes would air in the UK in April, though no US air date has been announced yet.

«Lost for 61 years! Best of all, these will be made available for FREE on the BBC iPlayer in April,» Davies wrote.

He expressed gratitude to Film Is Fabulous for finding the lost episodes and encouraged people to donate to the registered charity. «Maybe they’ll find more! As the Doctor says… ‘Daleks!'»

The episodes feature the first incarnation of the Doctor, played by William Hartnell, and a typical Dalek plot to take over Earth and the galaxy.

In the 1960s and 1970s, the BBC had a policy of destroying film or reusing videotapes, leading to dozens of episodes of Doctor Who and other popular UK shows like Dad’s Army and Top of the Pops going missing.

Old Doctor Who episodes do surface occasionally, and in 2016, the newly discovered soundtrack for one storyline was turned into an animated series called The Power of the Daleks.

Meanwhile, Disney ended its working relationship with the BBC last year, and star Ncuti Gatwa left the show. However, the UK broadcaster says that Doctor Who will continue, and Russell T Davies is working on a new Christmas special.
