You Aren’t Disinfecting Your Grimy Phone Daily? Here’s the Right Way to Clean It

Would you put your hands all over a dirty toilet seat? That’s what you’re effectively doing with your phone. Fortunately there are easy ways to keep it clean.

Even if you take good care of your phone, it’s impossible to escape the grit and grime of everyday use. And without routine cleaning, you’re inviting bacteria to develop — in fact, a phone is often dirtier than a toilet seat. Considering that Americans spend more than 5 hours a day on their phones, according to a December 2024 survey, it’s in the best interests of your health to make phone cleaning a regular habit.

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.

What a Proposed Moratorium on State AI Rules Could Mean for You

Congressional Republicans have proposed a 10-year pause on the enforcement of state regulations around artificial intelligence.

States couldn’t enforce regulations on artificial intelligence technology for a decade under a plan being considered in the US House of Representatives. The legislation, in an amendment to the federal government’s budget bill, says no state or political subdivision «may enforce any law or regulation regulating artificial intelligence models, artificial intelligence systems or automated decision systems» for 10 years. The proposal would still need the approval of both chambers of Congress and President Donald Trump before it can become law. The House is expected to vote on the full budget package this week.

AI developers and some lawmakers have said federal action is necessary to keep states from creating a patchwork of different rules and regulations across the US that could slow the technology’s growth. The rapid growth in generative AI since ChatGPT exploded on the scene in late 2022 has led companies to fit the technology in as many spaces as possible. The economic implications are significant, as the US and China race to see which country’s tech will predominate, but generative AI poses privacy, transparency and other risks for consumers that lawmakers have sought to temper.

«We need, as an industry and as a country, one clear federal standard, whatever it may be,» Alexandr Wang, founder and CEO of the data company Scale AI, told lawmakers during an April hearing. «But we need one, we need clarity as to one federal standard and have preemption to prevent this outcome where you have 50 different standards.»

Efforts to limit the ability of states to regulate artificial intelligence could mean fewer consumer protections around a technology that is increasingly seeping into every aspect of American life. «There have been a lot of discussions at the state level, and I would think that it’s important for us to approach this problem at multiple levels,» said Anjana Susarla, a professor at Michigan State University who studies AI. «We could approach it at the national level. We can approach it at the state level too. I think we need both.»

Several states have already started regulating AI

The proposed language would bar states from enforcing any regulation, including those already on the books. The exceptions are rules and laws that make things easier for AI development and those that apply the same standards to non-AI models and systems that do similar things. These kinds of regulations are already starting to pop up. The biggest focus is not in the US, but in Europe, where the European Union has already implemented standards for AI. But states are starting to get in on the action.

Colorado passed a set of consumer protections last year, set to go into effect in 2026. California adopted more than a dozen AI-related laws last year. Other states have laws and regulations that often deal with specific issues such as deepfakes or require AI developers to publish information about their training data. At the local level, some regulations also address potential employment discrimination if AI systems are used in hiring.

«States are all over the map when it comes to what they want to regulate in AI,» said Arsen Kourinian, partner at the law firm Mayer Brown. So far in 2025, state lawmakers have introduced at least 550 proposals around AI, according to the National Conference of State Legislatures. In the House committee hearing last month, Rep. Jay Obernolte, a Republican from California, signaled a desire to get ahead of more state-level regulation. «We have a limited amount of legislative runway to be able to get that problem solved before the states get too far ahead,» he said.

While some states have laws on the books, not all of them have gone into effect or seen any enforcement. That limits the potential short-term impact of a moratorium, said Cobun Zweifel-Keegan, managing director in Washington for the International Association of Privacy Professionals. «There isn’t really any enforcement yet.»

A moratorium would likely deter state legislators and policymakers from developing and proposing new regulations, Zweifel-Keegan said. «The federal government would become the primary and potentially sole regulator around AI systems,» he said.

What a moratorium on state AI regulation means

AI developers have asked for any guardrails placed on their work to be consistent and streamlined. During a Senate Commerce Committee hearing last week, OpenAI CEO Sam Altman told Sen. Ted Cruz, a Republican from Texas, that an EU-style regulatory system «would be disastrous» for the industry. Altman suggested instead that the industry develop its own standards.

Asked by Sen. Brian Schatz, a Democrat from Hawaii, if industry self-regulation is enough at the moment, Altman said he thought some guardrails would be good but, «It’s easy for it to go too far. As I have learned more about how the world works, I am more afraid that it could go too far and have really bad consequences.» (Disclosure: Ziff Davis, parent company of CNET, in April filed a lawsuit against OpenAI, alleging it infringed Ziff Davis copyrights in training and operating its AI systems.)

Concerns from companies — both the developers that create AI systems and the «deployers» who use them in interactions with consumers — often stem from fears that states will mandate significant work such as impact assessments or transparency notices before a product is released, Kourinian said. Consumer advocates have said more regulations are needed, and hampering the ability of states could hurt the privacy and safety of users.

«AI is being used widely to make decisions about people’s lives without transparency, accountability or recourse — it’s also facilitating chilling fraud, impersonation and surveillance,» Ben Winters, director of AI and privacy at the Consumer Federation of America, said in a statement. «A 10-year pause would lead to more discrimination, more deception and less control — simply put, it’s siding with tech companies over the people they impact.»

A moratorium on specific state rules and laws could result in more consumer protection issues being dealt with in court or by state attorneys general, Kourinian said. Existing laws around unfair and deceptive practices that are not specific to AI would still apply. «Time will tell how judges will interpret those issues,» he said.

Susarla said the pervasiveness of AI across industries means states might be able to regulate issues like privacy and transparency more broadly, without focusing on the technology. But a moratorium on AI regulation could lead to such policies being tied up in lawsuits. «It has to be some kind of balance between ‘we don’t want to stop innovation,’ but on the other hand, we also need to recognize that there can be real consequences,» she said.

Much policy around the governance of AI systems does happen because of those so-called technology-agnostic rules and laws, Zweifel-Keegan said. «It’s worth also remembering that there are a lot of existing laws and there is a potential to make new laws that don’t trigger the moratorium but do apply to AI systems as long as they apply to other systems,» he said.

Moratorium draws opposition ahead of House vote

House Democrats have said the proposed pause on regulations would hinder states’ ability to protect consumers. Rep. Jan Schakowsky called the move «reckless» in a committee hearing on AI regulation Wednesday. «Our job right now is to protect consumers,» the Illinois Democrat said.

Republicans, meanwhile, contended that state regulations could be too much of a burden on innovation in artificial intelligence. Rep. John Joyce, a Pennsylvania Republican, said in the same hearing that Congress should create a national regulatory framework rather than leaving it to the states. «We need a federal approach that ensures consumers are protected when AI tools are misused, and in a way that allows innovators to thrive.»

At the state level, a letter signed by 40 state attorneys general — of both parties — called for Congress to reject the moratorium and instead create that broader regulatory system. «This bill does not propose any regulatory scheme to replace or supplement the laws enacted or currently under consideration by the states, leaving Americans entirely unprotected from the potential harms of AI,» they wrote.
