You’re Probably Touching a Germ Factory Every Day and Calling It a Phone

Using the wrong products can damage the screen and protective coatings. Here’s the safest way to clean your grimy phone.

Americans spend more than 5 hours a day on their phones, according to a December 2024 survey. With that much handling, it’s no surprise your phone becomes a hotspot for bacteria — in fact, it’s often dirtier than a toilet seat. Since you hold it constantly and press it to your face, making regular phone cleaning part of your routine is more than just smart, it’s necessary for your health.

The FCC 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.

Luckily, there are safe and effective ways to sanitize your phone without causing any damage. We’ll guide you through the best methods and products for keeping your device germ-free, no matter if you have an iPhone or a Samsung or whatever its level of water resistance.

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.

TikTok Deal Will Keep It Online in the US, but Your Experience of the App Might Change

TikTok has secured its future by agreeing to split the US app from the global business. But the deal will spark changes to the app’s algorithm.

TikTok has dodged a ban and secured its long-term future in the US by announcing a deal on Friday that will see a joint venture take over US operations of the popular social video app. The deal marks the conclusion of a protracted battle over the app’s continued presence in the US, which dates back to President Donald Trump’s first term in office.

TikTok in the US will now be run by TikTok USDS Joint Venture LLC, which was established by a White House executive order issued in September 2025. At its helm will be CEO Adam Presser, previously the head of operations, who led TikTok’s efforts to ensure that the data of the app’s US users was kept secure. Shou Chew, the CEO of TikTok’s international operations, will serve on the joint venture’s board of directors.

«TikTok USDS Joint Venture’s mandate is to secure US user data, apps and the algorithm through comprehensive data privacy and cybersecurity measures,» the company said in a statement. «It will safeguard the US content ecosystem through robust trust and safety policies and content moderation while ensuring continuous accountability through transparency reporting and third-party certifications.»

The venture has three managing investors — Silver Lake, Oracle and MGX — which each hold a 15% stake. Oracle also will be responsible for protection of US user data and of the freshly retrained algorithm, which will be specific to the US version of the app.

Presidents Trump and Joe Biden raised concerns over a potential national security threat posed by TikTok, because of its Chinese-owned parent company ByteDance, which will retain a 19.9% stake in the new joint venture. During both of his presidential terms, Trump has attempted to ban TikTok, but also delayed the ban’s implementation.

The deal announced on Friday arrived moments before the deadline set by the White House for TikTok to comply with its September executive order. In a post on his social site Truth Social, Trump said he was «so happy to have helped in saving TikTok.»

«I only hope that long into the future I will be remembered by those who use and love TikTok,» said Trump. He also thanked China’s President Xi Jinping for working with the US and approving the deal. «He could have gone the other way, but didn’t, and is appreciated for his decision,» he said.

How TikTok might change for you

TikTok has more than 200 million users in the US, and if you’re one of them, the deal announced on Friday will allow you to continue using the app without the ongoing fear of it being banned.

It also won’t see you cut off from creators in China, or the rest of the world. People in the US will still be able to watch videos from Europe, such as last year’s viral «nothing beats a Jet2 holiday» trend. TikTok users outside of the US will still be able to follow their favorite American creators.

In the TikTok newsroom post, the company addressed interoperability, saying that the deal would «provide US users with a global TikTok experience, ensuring US creators can be discovered and businesses can operate on a global scale.»

Where the experience might change is in the content that is recommended to you. Under the terms of the deal, TikTok’s algorithm will be retrained, tested and updated based on US user data. This will have a knock-on impact on what you see on the platform, according to Kelsey Chickering, principal analyst at Forrester.

«TikTok’s power lies in its content graph — an algorithm that learns from thousands of user signals to deliver hyper‑relevant, highly addictive videos,» said Chickering. «With a US joint venture retraining that algorithm on domestic data, the experience will change — maybe for the better, maybe not. One thing’s certain: TikTok in America won’t be the same.»

In spite of the interoperability that will see US TikTok users connected to those across the globe, it does seem likely that the focus on US data will lead to a shift away from the global nature of the content that the algorithm currently serves up to you.

«TikTok’s US algorithm will now be trained on US data, which means what trends — and what dominates feeds — will feel distinctly American,» said Chickering. «Global content will still appear, but its ranking will change.»

Exactly how this will look may differ from person to person, and will likely take some time to come into effect as the joint venture begins the retraining process. TikTok didn’t immediately respond to questions regarding how long it expects retraining the algorithm to take, when US TikTok users should expect to be impacted by changes and whether it will issue public updates about this process.

One potential pitfall the company might want to avoid, Chickering said, is moderating the US version of TikTok in a way that tilts too far toward any one particular political viewpoint, or fails to curb misinformation. Elon Musk’s takeover of Twitter (now X) — and his subsequent algorithmic changes that alienated users and advertisers — is a cautionary tale in this regard. With Instagram Reels already vying to replace TikTok, the company will likely want to avoid making changes that could spark a mass exodus of people.

«For now, it’s speculation,» said Chickering. «It remains to be seen how new leadership will wield this power and whether moderation policies will evolve.»

‘Is Microsoft Down?’ Outlook and Teams Go Dark in Widespread Outage

It’s not just you: Numerous Microsoft services weren’t working most of Thursday, and the outage is continuing.

Thursday has been a tough work day for many — or maybe, a great one, depending on how eager you are to access work-related programs. Microsoft services, including Outlook, Teams and Microsoft 365 are experiencing a significant outage that’s still going on as of early evening, Pacific time. Microsoft hasn’t announced an expected time when everything will be back up and running.

You can follow the official Microsoft 365 Status account on the social-media platform X, which has been regularly posting updates about the outage.

The first post there, from 11:37 a.m. PT, said that the company was «investigating a potential issue impacting multiple Microsoft 365 services, including Outlook, Microsoft Defender and Microsoft Purview. Further information can be found in the admin center under MO1221364.»

The admin center is the dashboard for IT admins managing Microsoft 365 services.

You can also monitor Microsoft’s Service Health Status page. That page is noting that «users may be seeing degraded service functionality or be unable to access multiple Microsoft 365 services.»

A representative for Microsoft didn’t immediately respond to a request for comment.
