How to Clean Xiaomi Mi 9A: Safe Methods for All Parts of Your Smartphone

Xiaomi Mi 9A is a reliable device with a high-quality build, but even it requires regular cleaning. Dust, greasy fingerprints, garbage in connectors and speakers not only spoil the appearance, but can lead to breakdowns from poor microphone performance to overheating. In this article, we will discuss how to safely clean all elements of the phone — from the screen to the internal components — without risking damage to equipment.

The Mi 9A is a compact body and lacks official IP protection, which means moisture and fine particles can penetrate more easily than flagship models, so cleaning should be careful but thorough, and we will look at both mechanical methods (brushes, wipes) and software (memory cleaning of garbage), and give tips for pollution prevention.

Preparation for cleaning: what will be needed

Before you start cleaning, collect the necessary tools and materials, and use of inappropriate means (for example, high concentration alcohol or metal objects) can damage the coating of the case or display.

• 🧴 Microfibre wipe (without pile) - for the screen and body.
• 🧽 Cotton swabs (better with a plastic rod) - for hard-to-reach places.
• 🖌️ Soft brush (for example, for makeup) – to remove dust from connectors.
• 💧 Special cleaning fluid (or distilled water with 10% isopropyl alcohol).
• 🔌 Compressed air in a canister (optional) - for blowing dust from the speakers.
• 📱 Toothpick or plastic spatula - for careful removal of dirt from the cracks.

⚠️ Warning: Never use acetone, gasoline, solvents or household chemicals - they destroy the oleophobic screen covering and can damage plastic parts. Also avoid cotton-coated discs: their fibers can remain in connectors and speakers.

Screen and body cleaning: step-by-step instructions

The Mi 9A screen is covered with an oleophobic layer that repels fat and reduces fingerprints, but over time, this layer wears off and the dirt accumulates. To clean the display and body without damage, follow the algorithm:

1. Turn off your phone – this will prevent accidental touches and reduce the risk of sensor damage.
2. Remove the dust with a soft brush or a dry microfiber wipe. Movements should be light, without pressure.
3. Apply the cleansing liquid on a napkin (not on the screen!). Use minimal moisture.
4. Wipe the screen in circular motions, paying attention to the corners and edges. For persistent spots, repeat the procedure.
5. Dry the body with a dry napkin, especially around the buttons and camera.

For the back panel (if it is plastic), you can use a slightly wet wipe, but avoid getting liquid into the connectors. If there is a silicone case on the case, remove it before cleaning and wash it separately with warm water and soap.

1. Compressed Air: With short presses (no more than 1-2 seconds), blow the speaker holes. Keep the canister strictly perpendicular to avoid damaging the membrane.
2. Soft brush: Carefully swipe the speaker grilles to remove surface dust.
3. Tape or Scotch: Apply a piece of sticky tape to the grille and carefully remove it – this will help remove small particles.

⚠️ Warning: Never use toothpicks, needles or matches to clean speakers, they can tear the membrane. Also avoid liquids: getting moisture inside the case will lead to corrosion of contacts.

🔊 Sound test: After cleaning, check the speakers by calling another phone or turning on music. If the sound is cleaner, the procedure is successful. If not, repeat the cleaning or contact the specialists.
