Top most dangerous mistakes when cleaning your phone yourself

Keeping your smartphone clean is not only a matter of aesthetics, but also of health. We touch the screen dozens or even hundreds of times a day, bring the device to our face, put it on tables, in pockets or bags. Dust, microbes, and skin oils accumulate on the body and display.

Regular care extends the lifespan of your smartphone, but the desire to “remove dust on your own” often leads to damage. In this article, we will look at the most common mistakes and explain how to properly take care of your phone.

1. Using alcohol-based or aggressive products.
   Alcohol, acetone, glass cleaners, and household chemicals destroy the oleophobic coating of the display, which ensures smooth finger sliding and protection against greasy fingerprints. Such substances can also damage the protective layers of OLED and AMOLED displays, and sometimes even cause the glass to become cloudy.
   
   Correct:
   • Use only special cleaning fluids for displays.
   • A weak solution of isopropyl alcohol (up to 70%) is acceptable, but it should be applied only to a microfiber cloth, not directly to the screen.
   
   
   
2. Excessive wetting of the cloth.
   Water or liquid dripping from the cloth can easily get into the speakers, USB-C/Lightning connectors, or microphone holes. This leads to contact corrosion, board oxidation, and even short circuits.
   
   Correct:
   • Light dampening is the maximum. The cloth should be almost dry.
   • For hard-to-reach areas, it is better to use cotton swabs moistened with a minimal amount of cleaning agent.
   
   
   
3. Cleaning a working device.
   When the smartphone is turned on, it’s easy to accidentally press buttons, send a message, or make a call. But the main risk is moisture getting on an active board, which increases the chance of a short circuit.
   
   Correct:
   • Always turn off the phone and, if possible, remove the SIM card and memory card.
   • When cleaning around the connectors, you can even briefly disconnect the battery (but only if you know how to do it safely).
   
   
   
4. Cleaning connectors with improvised tools.
   Paper clips, pins, toothpicks, and needles can damage delicate charging port contacts or tear off protective elements. As a result, the smartphone may stop charging or connecting to a computer.
   
   Correct:
   • Use cans of compressed air.
   • Special anti-static brushes are acceptable.
   • If dirt has accumulated in the connector, contact a service center — in a workshop it can be cleaned with ultrasound.
   
   
   
5. Using household cloths and paper napkins.
   Paper has an abrasive structure and leaves micro-scratches. Ordinary cloths leave lint that gets stuck in speakers and connectors.
   
   Correct:
   • Use microfiber — a soft fabric that does not scratch the surface.
   • For deep cleaning, there are special wipes with anti-static impregnation.
   
   
   
6. Ignoring the case and accessories.
   Dirt accumulates not only on the phone, but also on its “companions.” Dust and grease from the case are quickly transferred to the body. An uncleaned cable may have poor contact, and dirty headphones become a source of bacteria.
   
   Correct:
   • Wash silicone and plastic cases in soapy water once a week.
   • Treat leather cases with special products.
   • Wipe cables with alcohol wipes.
   • Clean headphones with a brush and, if necessary, at a service center.
   
   

Cleaning a smartphone by yourself is not difficult, but it requires caution and proper tools. If you made a mistake and the device started to malfunction — do not experiment further. It is better to contact an authorized service center, where there is professional equipment for cleaning, drying, and restoring contacts. This way you will save both the device and your money.
