Your Phone Is Filthier Than a Toilet Seat. Here’s How to Fix That
Experts say your phone needs cleaning way more often than you think.
Your phone goes everywhere with you, but it rarely gets the cleaning it needs. From work meetings to gym sessions and even bathroom breaks, your device touches a lot of surfaces — and picks up a lot of germs along the way. In fact, studies show the average smartphone is often dirtier than a public toilet seat, collecting bacteria and viruses through daily use.
If you’re not disinfecting your phone regularly, all that grime sticks around, transferring to your hands, face and anything else you touch. The good news? You don’t need fancy tools or harsh chemicals to get it clean. With the right cloth, a safe cleaning solution and just a few seconds of care, you can wipe away the germs without damaging your screen or hardware. Here’s how to do it right.
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.Â
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.Â
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.Â
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.Â
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.Â
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.Â
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:Â
- Hand sanitizer: Fragrances and ethyl alcohol found in many sanitizers can harm your phone.Â
- 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.Â
- 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.

Chinaâs super-rich fled Singapore. Now they want to come back
Wealthy Chinese are reconsidering Singapore as Beijingâs offshore wealth scrutiny and geopolitical risks make alternatives less attractive.
A year ago, wealthy Chinese families were souring on Singapore. Its rules felt onerous, its nightlife subdued. Other cities seemed easier or more exciting.
Now they want to come back.
Family-office advisers and wealth managers say they are seeing renewed interest in Singapore from affluent Chinese clients who had shifted their lives to other financial centers, as tightening scrutiny from Beijing and geopolitical turmoil make its stability look attractive again.
The reversal underscores how quickly the calculations of Asiaâs wealthy can change.
Singapore emerged as a favored destination for wealthy mainland Chinese seeking to diversify their assets and gain distance from Beijing, particularly after Hong Kongâs 2019 protests and subsequent national security crackdown.
However, its appeal faded after a $3 billion money-laundering scandal in 2023 triggered tighter scrutiny of wealthy clients and family offices. Stricter compliance checks, lengthy bank onboarding and residency requirements pushed some Chinese families toward jurisdictions they viewed as easier or more appealing – such as Hong Kong, Dubai and Tokyo.
Theyâre now telling me I really want to come to Singapore to become a citizen.Ryan LinBayfront Law
But what once seemed restrictive is increasingly being viewed by some as a source of security.
âThe very reason why they came to Singapore in the first place back then was because Chinaâs policies impact Hong Kong much closer to them than in Singapore,â said Bayfront Law director Ryan Lin.
Lin, who advises wealthy Chinese clients on setting up family offices and securing residency in Singapore, said last year that he was increasingly helping clients move away from the city-state as tighter compliance and disclosure requirements eroded its appeal.
The shift comes as Beijing steps up scrutiny of wealth held outside mainland China. New rules affecting offshore trusts have rattled wealthy families because of requirements to disclose structures and potential tax liabilities, while tighter oversight has also extended to areas including insurance and offshore brokerage accounts. These rules can apply regardless of where a trust is located or where an individual physically lives.
âWhen it comes to the safety of their wealth, they probably now are considering Singapore very, very seriously for the long term,â he said, adding that they are more determined this time, with several asking about pathways to permanent residency and citizenship as they consider making Singapore a longer-term base.
Moving to Singapore does not automatically sever an individualâs obligations to China, said Carman Chan, founder of Hong Kong and Singapore-based family office Click Ventures, particularly without a change in citizenship or tax status.
Advisers say the renewed interest in Singapore is generally about creating physical, financial and political distance from the mainland while maintaining additional options.
Lin said recent restrictions affecting mainland investorsâ access to offshore brokerages in Hong Kong had particularly unsettled some clients. âThey find perhaps Hong Kong is really too close to China,â he said.
Manish Tibrewal, co-founder of family office Farro Capital, said his firm has seen a sharp pickup in inquiries from Chinese families considering to relocate to Singapore.
A spokesperson for Hong Kongâs Financial Services and the Treasury Bureau said that under the âone country, two systemsâ framework, âHong Kong upholds the common law system, the free flow of capital, the free convertibility of its currency, a simple and low tax regime, and a regulatory framework aligned with international standards.â
Dubai reversal
Singapore is also benefiting from a different source of anxiety: the Middle East.
Several advisers, including Tibrewal and Lin, said Chinese families who shifted toward Dubai in recent years have reconsidered their plans amid conflict in the region.
Lin said some of his clients initially treated the conflict as a temporary shock. But as tensions persisted, families began taking more concrete steps to leave.
âMy clients are afraid that Dubai may potentially be easy collateral damage.â Lin said. âTheir sense of security will not be there. They will be frantic. At least mentally, they wonât feel very safe. Their mindset of managing money in Dubai has changed.â
Some have already returned while others are unwinding investments and financial arrangements before doing so, he said.
Japanâs barriers
Tokyo had become attractive to wealthy Chinese in recent years as a weak yen made everything from property to luxury goods cheaper. Its proximity to China and safety had also made it an obvious alternative to Singapore.
Yet language barriers, difficulties integrating into Japanese society and differences in business and social culture caused issues, advisers said.
Iris Xu, CEO of Jenga Business Consulting Group, a consultancy that works with wealthy families, cited one client who relocated to Japan but returned to Singapore after just eight months.
âAfter going to Japan, going to Dubai, going to Hong Kong, there remains the Singapore option,â Xu said.
Back to Singapore
The renewed interest also arrives as Singapore itself fine-tunes the rules governing its family-office industry.
The Monetary Authority of Singapore in July eased some conditions for single-family offices seeking tax incentives, with the changes taking effect Aug. 1. The revisions give offices greater flexibility on hiring and investment requirements even as authorities continue to strengthen checks on the sources of wealth entering the country.
âWealth owners from a diverse range of countries choose Singapore for many reasons, including our high standards of regulation, strong rule of law, and a comprehensive ecosystem of wealth managers and professional service providers,â an MAS spokesperson told CNBC.
Advisers for the wealthy say Singaporeâs advantage is increasingly the predictability that comes with its rules.
âTheir priorities have changed,â Xu said. âBefore, maybe they were looking for an opportunity. Now they are looking at safety.â

U.S.-Iran escalation shows Washington’s frustration with slow-moving sanctions
Renewed hostilities reopen the question of whether the conflict is grinding toward a settlement or further escalation.
The escalation in hostilities between the U.S. and Iran over the weekend shows the U.S. is running out of patience with the slower-moving sanctions approach, according to analysts.
U.S. forces destroyed two Iranian rocket launchers on Larak Island on Sunday, as the Islamic Republic prepared to fire mine-carrying rockets into the Strait of Hormuz, ending a month-long lull in direct fighting.
The strike was the first publicly acknowledged U.S. attack since late July. Iran responded within hours, firing eight missiles at the King Hussein and Al Azraq air bases in Jordan. Jordanian air defenses intercepted all eight, with no casualties, the government said.
Later Sunday, President Donald Trump threatened on social media to blow up Kharg Island, Iranâs main oil-export hub, to âsmithereens.â
âMost of the war has been tactically focused rather than strategic from the outset,â said Ian Ralby, a maritime security expert and president of Auxilium Worldwide. âThe question, therefore, is: why this, why now?â
The sanctions campaign may not be hurting Iranâs leadership fast enough for the U.S.âs liking, Ralby said. Treasury Secretary Scott Bessent told Reuters on Sunday that he expects new sanctions on Iran weekly, particularly targeting banks, and that Washington intends to cut Tehran-linked institutions out of the dollar system entirely.
âIt may be that the financial pressure was not curtailing Iranian behavior to the level the U.S. anticipated,â Ralby said. Renewed Iranian military activity may also have threatened U.S. forces or interests in the region âat a sufficiently high level of gravity that the U.S. felt it necessary to strike Iranian territory once more.â
The U.S. strike is likely an attempt to break a deadlock rather than a shift in policy, Ralby added. âThe status quo has become somewhat stagnant, and Iâm sure the U.S. would like to see that change,â he said. But it is unlikely to alter âthe continuation of the blockade, or the economic âwarfareâ being used to try to pressure Iran.â
Potential escalation
Trumpâs threat against Kharg Island is likely to remain rhetorical. The terminal has absorbed dozens of strikes since the war began, with its oil infrastructure deliberately spared.
âIt is unlikely that the President of the United States will actually carry through on the threat to attack Kharg Island,â Ralby said, noting the island also holds a historic early church that Iran has worked to preserve.
An attack âwould be a destruction of cultural heritage as well as destruction of critical oil infrastructure, which would likely cause catastrophic environmental harm,â he said. âThreatening it may seem appealing, but actually blowing it up should hold little appeal.â
Rather than confronting U.S. forces head-on, Iran is more likely to retaliate through proxies and pressure on shipping and energy flows.
âThe key to this conflict from the outset has been asymmetry,â Ralby said. âThe Iranians have demonstrated an ability to use limited actual force to inflict substantial, actual harm.â
For instance, the Houthis, who control a large part of Yemen and have held sway over the approaches to the Bab el-Mandeb for the better part of a decade, entered the war weeks ago in support of Iran.
With the Houthis restricting navigation through the Bab el-Mandeb, the U.S. and its allies in the region could face a situation where the two major maritime chokepoints used to export the majority of the Gulfâs petroleum products are âsubject to manipulation by Iran and its partners,â said Michael Ratney, senior adviser at the Center for Strategic & International Studies.
âWe always assume that the Houthis and Iran are part of the same kind of group, but theyâre not,â said Claudio Galimberti, chief economist at Rystad Energy. âThey have worked in the past quite independently.â
Somali piracy, dormant since 2013, has also returned as coalition navies concentrate on the Red Sea and Hormuz. At least five vessels are currently held, including a tanker seized off Al Mukalla on Aug. 20.
âEnhanced pressure on oil production, the energy market, and global shipping are likely to be the focal points for Iranian retaliation,â Ralby said.
The military campaign remains the dominant force in oil prices. Flows through the strait reached roughly 7 million barrels a day last week via the Omani corridor under U.S. Navy escort, according to Galimbertiâs estimates, calling it âa very costly mechanism … but itâs working.â
The strike on Larak threatens to reverse that recovery, injecting fresh uncertainty into commercial shipping through the waterway. âThe expectation is that the flows in the next couple of days probably will be lower, and therefore you should expect the price increase for sure,â Galimberti said.

CNBC Daily Open: Trump wants to floor it on economic growth as Warsh eyes the brakes
The Trump administration saw two embattled officials fending off criticism yesterday as the war in the Middle East flared up again.

Hello, this is Hui Jie writing to you from Singapore. Welcome to another edition of CNBCâs Daily Open.
The Trump administration saw two embattled officials fending off criticism yesterday as the war in the Middle East flared up again, with U.S. President Donald Trump trying to lower pump prices and talk up growth.
Treasury Secretary Scott Bessent also defended the decision to increase bond purchases earlier last month, after investor Stanley Druckenmiller criticized the move.
If you were working late in Asia last night, you may not have caught any of this, simply because Microsoft Outlook and ChatGPT Work experienced outages. I know of more than a few office workers that were secretly grateful for that.
What you need to know today
U.S. President Donald Trump has unveiled a cunning plan to combat high pump prices for Americans, involving his claimed control over 65 billion barrels of oil reserves in Venezuela.
He will meet with U.S. refiners and fuel distributors, looking for ways to expand domestic refining capacity and bring down gasoline prices, according to a White House official.
Prices at U.S. pumps were at $4.08 per gallon on average nationwide Monday, according to AAA data, which is nearly 30% higher compared to the same time last year.
However, there is just one snag. Experts told CNBC that his deal with Venezuela will not lower gas prices anytime soon.
Venezuelaâs oil infrastructure is in a state of disrepair, and it will require about $180 billion of investment till 2040 to return the country to peak production, according to Rystad Energy.
The South American nation is currently producing around 1.2 million barrels a day, down from a peak of 3.5 million bpd in the late 1990s.
Trump also has one eye on the Middle East, vowing to hit Iran âhardâ after the Islamic Republic said it launched an attack on two U.S. bases in Jordan.
The strikes âdestroyed the technical and repair infrastructure, as well as the enemy fighter deployment sites,â inflicting âheavy damage,â Iranian military forces reportedly said, while vowing increasingly forceful responses.
Growth and the Fed
Trump also continued his push for the Fed to lower interest rates, arguing that the U.S. could grow at rates of up to 20% (yes, that is not a typo), and adding such rapid growth should not prompt the central bank to raise interest rates.
âSuccess in growth does not cause inflation,â the U.S. president said. However, growth has never reached anywhere close to the levels Trump is saying, except for one Covid pandemic-related surge of 34.9% in 2020, which notably followed a 28% contraction in the previous quarter.
The most recent GDP numbers, however, are a far cry from the 20% annualized growth touted. Real GDP increased at a 1.5% annualized rate in the second quarter of 2026, down from 2.1% in the first quarter, according to the BEAâs latest estimate.
The presidentâs stance would then put him at odds with Fed Chairman Kevin Warsh, who is expected by markets to hike rates at the Fedâs meeting in September.
Odds for a move at the Sept. 15-16 meeting jumped to 66.1% on Monday, nearly double where they were before Warshâs speech at Jackson Hole over the weekend, according to the CME Groupâs FedWatch tool.
Treasury Secretary Scott Bessent, meanwhile, defended the departmentâs decision to double the planned size of buybacks of longer-dated U.S. bonds.
Investor Stanley Druckenmiller, Bessentâs former mentor, argued that the policy amounted to âprice managementâ rather than an attempt to improve market liquidity, and risked undermining the Treasuryâs credibility.
Outlook and ChatGPT outages
But the most important news for office workers Monday stateside would be that they had a rare reprieve from some of their work, as Microsoft Outlook and OpenAIâs ChatGPT Work experienced outages.
Users reported problems with Outlook, while OpenAI said users may experience problems starting or continuing tasks in ChatGPT Work, temporarily disabling two of the modern officeâs favorite methods of assigning more work.
Anyone who failed to send an email, and then failed to ask AI to write an excuse for not sending that email, finally could legitimately say âI couldnât do it, honest!â

And finally…
FTC sues Amazon, accusing the e-commerce giant of misleading advertisers
The Federal Trade Commission on Monday sued Amazon, alleging the e-commerce giant âsecretly and systematically overchargedâ advertisers on its platform by manipulating its pricing and auction systems.
The lawsuit, which was joined by 22 state attorneys general, argues that Amazon may have reaped more than $20 billion from advertisers by using âhidden surchargesâ dating back to a change to its auction rules that took effect in 2019.
However, the company argues that its auction systems have saved advertisers $8 billion between 2021 and 2025, not cost them extra.
