Studies showing that smartphone surfaces can carry up to 10 times more bacteria than a toilet seat are fairly well known.

​

When you think about how often we game, scroll through YouTube Shorts, and browse the web while constantly touching the screen all day, it does not really sound exaggerated.

​

Even so, not as many people clean their phones regularly as you might expect.

​

Today, I’ll go over how to keep your phone properly clean without damaging it.

Basic Routine

Before you start cleaning your smartphone, turn it off and disconnect the charging cable first.

​

Next, wash your hands with soap for at least 20 seconds and dry them completely. That helps keep any dirt or germs on your hands from transferring right back onto the phone.

​

Then remove the case and clean it separately. If it is a silicone, TPU, or plastic case, add a small amount of mild detergent to lukewarm water, wash it gently by hand, rinse it well, and let it dry completely.

Pay attention to the 70% mark. These days, you can even find disinfecting wipes made specifically for electronics.

For the phone itself, start with a dry microfiber cloth, then lightly dampen it with 70% isopropyl alcohol or an electronics disinfecting wipe with 70% alcohol and wipe the device down.

​

There is one key precaution here. Never spray liquid directly onto the phone. Always apply it to the cloth first.

​

Be careful not to let liquid reach the speaker holes or the area around the charging port, and use only a dry soft brush or a dry cotton swab to gently remove dust from those areas. To finish, wipe the phone once more with a dry microfiber cloth to remove any remaining moisture, then put the fully dried case back on.

​

In short, the three essentials are 70% alcohol + microfiber cloth + no direct spraying.

Check the ethanol or alcohol concentration carefully. This product is 83%, so it needs to be used with caution.

You can also use alcohol pads that are easy to find online. Alcohol pads with an alcohol content of around 60% to 70% (such as ethanol) are the safer choice.

​

If possible, it is better to avoid anything over 80%, and no matter what product you use, using it too often can wear down the coating, so keep the frequency moderate.

If the basic routine does not feel like enough, you can consider a UV sanitizer. Just make sure to check whether it has KC certification and verified official test data before you buy it.

​

Using an antibacterial coated case is another option as well.

​

That said, do not rely too heavily on these tools. In the long run, paying more attention to the everyday habits covered below is much more effective.

Cleaning Methods to Avoid

Do not assume, “The phone screen is glass, so this should be fine to use on it.”

On the other hand, plenty of phones get damaged simply because they are cleaned the wrong way.

​

Harsh chemicals such as bleach, chlorine-based cleaners, glass cleaner, acetone, and ammonia-based detergents can damage the display’s oleophobic coating, which leads to more smudging and a worse touch feel.

​

Pouring or spraying water or detergent directly onto the screen is also risky. Even with a waterproof phone, liquid can still get into ports or microphone openings and cause corrosion or a short circuit.

Applying gel-type hand sanitizer to your phone is another thing to avoid. Besides alcohol, these products can leave behind moisturizers and fragrance ingredients, which can cause stickiness and streaks.

​

Also, rubbing hard with tissues, paper towels, or the edge of your clothes is not a good idea. Those fibers are rougher than they look, so fine scratches can build up over time. And if you use wet wipes to dig into gaps and clean them, moisture can collect there and lead to malfunctions.

Bad Everyday Habits

Your everyday habits matter just as much as your cleaning routine.

​

One common example is taking your phone into the bathroom. In surveys, more than half of medical workers said they use smartphones in the bathroom, and there have been cases where intestinal bacteria were detected.

​

Keeping your phone in a pocket or bag with keys, coins, or cards is also best avoided. It is not just a scratch issue—contaminants can transfer directly as well, so having a separate compartment for your phone is a much better option.

Leaving your phone directly on a restaurant table when eating out is another similar habit. Since you never really know how well each place has been sanitized, it is better to place it on top of your bag or on a dedicated pouch.

​

Above all, wash your hands first before touching your phone after coming home or before meals. That alone can reduce contamination quite a bit.

​

Lastly, check the condition of your case and screen protector about once a week. If discoloration or tearing is severe, replacing them is better for both hygiene and device protection.

Wrapping Up

That covers how to keep your smartphone clean. Lately, I have been spending a lot of time holding my phone with both hands while playing 카러플, so this definitely makes me think I need to be more careful about managing it.
