How to Properly Sanitise a Smartphone: 7 Powerful Steps for Total Hygiene

Smartphones are an essential part of modern life—they’re always with us, whether we’re at home, in the office, or on the move. That also makes them prone to collecting germs, dirt, and grime. Learning how to properly sanitise a smartphone is crucial not just for cleanliness but also for extending your device’s lifespan. Below, we outline seven simple steps to keep your phone safe, sanitary, and free from unnecessary wear and tear.

Why It Matters: According to The Centers for Disease Control and Prevention, high-touch surfaces like phones should be regularly cleaned to reduce the spread of germs. Also, many manufacturers (e.g., Apple’s official guidelines) offer specific instructions on safe device cleaning.


Step 1: Power Down and Disconnect Accessories

  • Safety First: Always turn off your smartphone and unplug any charging cables or headphones before cleaning.

  • Reason: This reduces the risk of electrical short circuits and potential damage from moisture.

Phone Cleaning Tips: If you have a protective case, remove it so you can sanitise the phone body and the case separately.

Step 2: Gather the Right Tools

To disinfect your phone without causing damage, you’ll need:

  1. Microfiber Cloth: Lint-free and gentle enough for delicate screens.

  2. 70% Isopropyl Alcohol Wipes or 70% Ethanol Wipes: According to CDC guidelines, a 70% alcohol solution effectively kills most pathogens.

  3. Small Soft Brush or Cotton Swabs: Helps remove debris from speaker grilles and ports.

  4. Mild Dish Soap (Optional): For stubborn grime on phone cases (avoid direct use on the device unless the manufacturer explicitly allows it).

Important: Double-check your smartphone manufacturer’s recommendations. Some devices have coatings or materials that may require more specific cleaning products.

Step 3: Remove Surface Debris and Dust

  • Light Shake: Gently tap the phone against your palm to dislodge dust from the ports.

  • Soft Brushing: Use a small, clean brush or cotton swabs to remove lint from speaker holes or charging connectors.

  • No Compressed Air: Many manufacturers caution against using compressed air directly on your phone, as it could damage internal components.

Best Phone Sanitisation Methods: Keeping ports free of debris helps maintain clear audio and reliable charging connections.

Step 4: How to Properly Sanitise a Smartphone with the Right Cleaning Solution

  • Dampen a Microfiber Cloth: Lightly moisten it with a 70% isopropyl alcohol or ethanol solution.

  • Avoid Excess Liquid: Never drench the cloth or spray cleaner directly on the screen—excess moisture can seep into the device.

  • Gently Wipe: Clean the front screen using slow, circular motions, then move on to the back and sides.

Pro Tip: For a phone with a glass coating or an oleophobic layer, don’t press too hard. Gentle motions help preserve that protective finish.

Step 5: Sanitise Crevices and Buttons

  • Cotton Swab Detail: If any residue remains around buttons or seams, use a cotton swab with a tiny bit of alcohol solution.

  • Speaker Grille: Tilt the phone at an angle so that any liquid drips away from the speakers.

  • Avoid Ports: Use minimal moisture near charging or headphone ports to prevent short circuits.

Disinfect Your Phone Thoroughly: Microbial hotspots often form around volume buttons and the power key, so pay extra attention there.


Step 6: Clean and Disinfect Your Phone Case

  • Materials: Cases come in plastic, silicone, leather, and other materials. Check manufacturer guidelines or packaging for cleaning instructions.

  • Gentle Soap and Water: For most rubber or silicone cases, mild dish soap and warm water work well. Rinse thoroughly and let it air-dry.

  • Leather Cases: Use a dedicated leather cleaner or a damp microfiber cloth. Follow up with a leather conditioner if needed.

  • Disinfect: If your case tolerates alcohol, you can also wipe it down to kill germs.

Be sure the case is fully dry before reassembling it with your phone.

Step 7: Let It Air-Dry and Inspect

  • Dry Time: After sanitising, let your phone air-dry on a clean surface for at least 5–10 minutes. This allows any residual moisture or disinfectant to evaporate.

  • Reassemble: Put your case back on only when you’re sure both sides are completely dry.

  • Final Check: Power on your phone and test buttons, speakers, and ports to confirm everything is functioning correctly.

Phone Cleaning Tips: Consider repeating these steps at least once a week if you use your phone frequently in public spaces. If you handle it often in high-contact environments, more frequent cleaning may be advisable.


Common Mistakes to Avoid

  1. Overusing Liquid Solutions: Too much moisture can damage internal electronics.

  2. Applying Harsh Chemicals: Bleach or abrasive cleaners can degrade screen coatings.

  3. Using Paper Towels: These can scratch the screen surface due to their rough texture.

  4. Skipping the Case: Even if the phone is sanitised, a dirty case can quickly re-contaminate it.
