Xiaomi Redmi smartphones are reliable, but even they require regular maintenance. Dust in the speakers, greasy traces on the screen, clogged connectors or crowded memory can spoil the experience of use. Improper cleaning often leads to damage to the coating, moisture entering the body or failures in the operation of sensors. This guide provides step-by-step instructions for safely cleaning all Redmi elements, from exterior surfaces to interior components, taking into account the features of different models (from Redmi Note 10 to Redmi). 13C).
We will discuss what you can and can not clean your smartphone, how to remove dirt from hard-to-reach places (for example, from under the camera or under the buttons), and what to do if the device began to slow down due to a full memory, and pay special attention to the myths of βmagicβ cleaning products β alcohol, vinegar or toothpaste, which are often recommended on the Internet, but which actually destroy the oleophobic screen coverage or corrodate contacts.
If your Redmi overheats, discharges quickly, or gives up errors when connecting the charging, the reason may lie in the accumulated dirt. Follow our recommendations, and your device will last longer without repair.
1.Preparation for cleaning: what will be needed
Before you start cleaning, gather the necessary tools and materials. Using the wrong tools is the main cause of damage to smartphones. For example, paper wipes scratch the screen, and cotton swabs can leave fibers in the connector. USB-C.
Here is the Redmi Safe Cleaning Kit:
- π§΄ Microfiber fabric (without pile, as for glasses) - for the screen and body.
- π¨ Compressed air balloon (or soft makeup brush) β to remove dust from speakers and connectors.
- π§Ό Special wipes for electronics (with isopropyl alcohol not more than 70%) - for disinfection.
- π Plastic or wooden toothpick β for cleaning ports carefully.
- π± Cleaning gel for smartphones (optional, to remove sticky traces).
What should not be in your arsenal:
- π« Household detergents (soap, shampoo, glass washing agent) - leave divorces and damage the coating.
- π« Abrasive materials (sandpaper, hard sponges) - scratch metal and glass.
- π« Acetone, vinegar, gasoline - dissolve glue and plastic.
- π« Wet wipes for hands - contain aggressive surfactants.
β οΈ Note: If your Redmi is certified IP53 (For example, the Redmi Note 12 Pro+), It doesn't mean it can be washed underwater, spray protection doesn't equal water resistance, and getting liquid under the body voids the warranty.
Screen cleaning: remove prints and divorces
The screen is the most vulnerable part of the smartphone, and it accumulates fat, sweat and germs, and improper cleaning can damage the oleophobic coating (it is responsible for a slight slip of the finger), if you leave the wiring after you wipe it or the screen becomes sticky, you use the wrong tool.
Step-by-step:
- Turn off your smartphone (or put it in flight mode) to avoid accidental touches.
- Remove large dust particles with dry microfiber tissue with light circular movements.
- If there are greasy traces, slightly moisten the fabric with distilled water or a special spray for electronics (do not apply the liquid directly to the screen!).
- For disinfection, use isopropyl alcohol wipes (no more than 70%!) - they kill 99% of bacteria.
To remove persistent stains (for example, from cream or cosmetics), you can use a cleaning gel:
- Put a small amount of gel on the screen.
- Rub it with a soft cloth.
- Remove the residues with a dry microfiber.
β οΈ Warning: Never use alcohol wipes for injections - they contain additives that corrode the screen covering. Also avoid wipes for monitors - they are often soaked in silicone that leaves the film behind.
π‘
If the oleophobic coating is damaged (the finger clings to the screen), it can be restored using special formulations, for example, Liquid Nano Coating from Xiaomi, applied as a protective film and lasts 3-6 months.
Cleaning of the hull and chamber
The Redmi case (especially the matte-coated models like the Redmi Note 11) collects dust and greasy traces. The camera often suffers from dirt hitting the lenses, leading to blurry photos.
How to clean the case:
- π§½ Wipe the back panel with a moist microfiber cloth (no alcohol to damage the logo).
- π To clean the indentations around the chamber, use a soft toothbrush (new!) or brush.
- π¦ If the case is sticky (for example, after using a car holder), apply a little soap solution (1 drop of the product per glass of water) to the fabric and gently wipe, then dry.
Cleaning the camera module:
- πΈ Remove dust from the lenses with compressed air (keep the balloon at a distance of 5-10 cm).
- π§΄ For persistent stains, use napkins for optics (without alcohol!).
- π« Donβt press the camera glass β itβs thinner than the main screen and can crack.
Pay special attention to the notch under the camera, which accumulates the most dirt. If you notice black dots in the photo (artifacts from dust), try blowing the hole with a hairdryer in cold air (do not use hot stream!).

4. Cleaning the connectors: USB-C, 3.5 mm, SIM-tray
Clogged connectors are a common cause of problems with charging, sound or network. USB-C The Redmi port is filled with dust, pile from your pockets, and even metal shavings (if you carry your key phone often), cleaning requires care: one wrong move and you bend the contacts.

- π§Ή Remove the dust with a brush.
- π« Do not use metal objects β they can scratch the O-ring (if there is one).
β οΈ Note: If after cleaning USB-C charging still doesn't work, check the port for bending contacts (a common problem after using unoriginal cables.
5. Removal of dust from speakers and microphones
Clogged Redmi speakers cause sound distortion and microphone dust to cause poor hearing during calls. In stereo models (such as the Redmi Note 12 Pro), dirt accumulates especially quickly due to the increased number of holes.
How to clean the speakers:
- π Blow the holes with compressed air (hold the balloon vertically to avoid liquid ejection!).
- π΅ To remove persistent dirt, use sticky tape to clean keyboards (neatly press and remove).
- π« Do not pick holes with a needle or toothpick - this will damage the speaker's mesh.

If the speaker started wheezing after cleaning, it's possible that the dust got inside the membrane, and in this case, only disassembling the device in the service will help.
π‘
Regular cleaning of speakers (every 2-3 months) prevents moisture buildup inside the case, which is especially important for models without official water protection (for example, Redmi). 10A).
6. Cleaning internal memory: removing digital garbage
Physical dirt isn't the only problem. The memory, the app cache, and the duplicate files are slowing down the smartphone as much as the dust in the connectors. MIUI There are built-in optimization tools, but they donβt always cope with deep cleaning.

If the smartphone is still slowing down:
- π Restart the device (hold the power button for 10 seconds).
- π οΈ Reset the settings to factory (pre-reverse the backup!).
- π Turn off animation in Settings β The phone. β Version. MIUI (Click 7 times on the version, then go to the Developer Settings β Scale of animation and choose No animation).
