The use of wireless headphones, such as the popular Xiaomi Redmi Buds or Mi True Wireless Earbuds, inevitably leads to contamination of the charging case. Dust, pile from pockets, skin fat and particles of earwax accumulate in hard-to-reach places, which not only spoils the aesthetic appearance of the accessory, but can also disrupt the charging process. Many users ignore the need for regular care until they are faced with a situation where the headphones stop charging or the case stops opening automatically.
In this article, we will discuss proven methods to effectively and safely clean the case from Xiaomi headphones. You will learn what tools are necessary for delicate cleaning, how to remove ingrained dirt from contacts and why the use of aggressive chemistry can be a fatal mistake for your device. Proper care will prolong the life of the gadget and preserve its original appearance.
Before you start to act, it is important to understand the design of your device. Different Xiaomi models have different degrees of moisture protection and build, which dictates their cleaning rules. Some cases can be wiped with a wet wipe, while others require exclusively dry treatment.
Tools and workplace preparation required
You don't need specialized equipment to clean your charging case properly, but using inappropriate items like metal needles or hard brushes can cause scratches on the plastic and damage to the internals, and the basis of a successful procedure is choosing the right tools that don't harm the electronics and the outer coating.
First of all, you need a source of compressed air, which can be a can of compressed air to clean the optics, or a special pear to clean the camera lenses, compressed air allows you to blow dust out of deep depressions that you can't get to mechanically, and if you don't have a can, you can use a soft brush to paint with a natural pile, but you need to be extremely careful.
To remove sticky contaminants and disinfect, prepare isopropyl alcohol (isopropanol) with a concentration of at least 70% or special wipes for cleaning electronics. The use of tap water is strictly prohibited due to the risk of contact oxidation and mineral salts entering the device, you will also need cotton swabs (better with thin plastic rods, not wooden ones that can break) and microfiber.
💡
Use only microfiber lintless wipes, as ordinary fabric or paper towels may leave small villi that will clog the speakers or charging contacts again.
Step-by-step instructions for dry cleaning of the case
You should always start with a dry cleaning, which will remove the bulk of the dust and debris without the risk of turning them into mud when in contact with the liquid. First, remove the headphones from the case and carefully examine the interior space. Pay attention to the corners and magnets that hold the headphones, which is where the pile accumulates most.
Use a dry soft brush or a soft bristling toothbrush to sweep out large debris. The movements should be sweeping, from center to edge. Then apply compressed air: point the jet at an angle inside the case to blow dust out of the cracks and charging holes. Don't bring the spray spout too close so that the condensate or the jet is too powerful doesn't damage the fine parts.
☑️ Basic dry cleaning
Pay special attention to the contact areas. At the bottom of the headphone indentations are golden or silver contacts that transmit energy. If you see a plaque on them, walk carefully with a dry cotton swab. Do not use force, because the contacts can be slightly drowned or protruding, and they are easily damaged.
⚠️ Warning: Never use metal objects (clips, needles, scissors) to pick inside the case.One awkward movement can short-circuit or mechanically damage the spring mechanisms.
Wet treatment and surface disinfection
After removing the main dust, you can proceed to a more thorough cleaning, to do this, slightly moisten the corner of a microfibre wipe or a cotton swab in isopropyl alcohol. It is important that the fabric is wet, not wet: when pressed hard, it should not drip liquid. Alcohol quickly evaporates and degreases the surface, removing traces from fingers and sweat.
Rub the exterior and interior surfaces of the case, avoiding direct liquid entering the speaker holes or the charging connector. If your Xiaomi model has an LED indicator, try not to rub it aggressively so as not to scratch the transparent window. For hard-to-reach places, cotton swabs dipped in alcohol are ideal.
Here is a table that will help determine what tools can be used for different parts of the case:
| Part of the case | Recommended remedy | Prohibited funds | Frequency of cleaning |
|---|---|---|---|
| Outer hull | Microfibre, isopropanol | Acetone, gasoline, abrasives | Once a week. |
| Internal contacts | Dry cotton swab | Water, wet wipes. | When you have a charge problem. |
| Dinami (grid) | Dry soft brush | Liquids, sharp objects | Once a month |
| Magnets | Dry toothbrush | Metallic objects | Every two weeks. |
After wet treatment, allow the case to dry completely for 5-10 minutes before putting the headphones back in. Even the rapidly evaporating alcohol should have time to escape from the microslits. Make sure there are no cotton swab villi left inside.
Removal of complex contaminants and soot
Sometimes, the contacts or the inside of the case can become more persistent contaminants that are not removed by dry cleaning, it can be oxidized plaque or compressed dirt, in which case you can use the "compress" method for contacts: wind a cotton swab a little cotton, moisten it in alcohol and apply it to the contact for a few seconds, then gently wipe it.
If the contamination is sticky (such as spilled sweet liquid), you need to act quickly and carefully. The sticky substance can attract dust and block the operation of the case lid. Use a minimum amount of alcohol and repeatedly wipe the contamination area with the clean side of the wipe until the stickiness disappears.
To clean the speaker grid, if it gets dirty, you can use the duct tape method, cut a small piece of tape, roll it with the sticky side out, and gently apply it to the grid to pull out the dust. Don't push hard so you don't damage the speaker membrane.

Cleaning the headphones themselves before returning to the case
It's pointless to clean a case if you're bringing back dirty headphones. TWS-Headphones are earwax that clogs the speaker's grid and stains the charging contacts. Before you put the gadget in a clean case, be sure to process the headphones themselves.
Remove the silin embroideries (if the model allows) and rinse them with warm water and soap, thoroughly dried before installation. Wipe the earphone body with an alcohol wipe. Pay special attention to the contact areas on the leg or end of the earphone - they should be perfectly clean and dry.
Use a dry toothbrush to clean the speaker mesh. Walk around the surface in a light circular motion to remove plaque. If the mesh is heavily contaminated and the sound is quieter, you may need to change the mesh or professionally clean, but at home brush and tape are the best assistants.
⚠️ Warning: Make sure the headphones are completely dry after cleaning the bottles or case.Damping into the case charger compartment through a wet earphone can cause the case contacts to corrosion.
Typical errors and precautions
Many users make mistakes that cause them to break down, and the most common mistake is using household chemicals that contain chlorine, ammonia, or abrasive particles, which break down plastic, make it cloudy, and can damage the protective coatings of the contacts.
Another common mistake is to overdo it with fluids, and people pour alcohol or water in excess, thinking it's going to be cleaner, but the fluid leaks under the plastic cells, causing the board to oxidize and stick to the buttons, and remember that the case is a complex electronic device, not a plastic food container.
Also, you shouldn't use a vacuum cleaner to clean your case, because the suction power of a household vacuum cleaner can be too high for the small parts of the headphones or even the case itself, and the static electricity that comes with it can theoretically damage the electronics.
💡
The main rule of cleaning electronics: it is better to carry out the procedure three times with a minimum amount of moisture than once pour the device abundantly, risking damage.
Pollution prevention and care
To avoid having to do a lot of cleaning, follow simple rules of operation. Try not to put the case in pockets with a pile (for example, fleece or terry fabrics) without an additional protective case. Silicone cover covers not only protect against scratches, but also collects the bulk of the dust on itself, which is easy to wash off with water.
Regularly, at least once a week, wipe the case with a dry microfiber. This will not take long, but will prevent the accumulation of fatty plaque, which over time hardens and becomes difficult to remove. Also monitor ear hygiene, as this directly affects the rate of contamination of the earbuds and, as a result, the case.
If you notice that the case has started to close worse or the headphones are not fixed with magnets as tightly as before, most likely the problem is contamination of the magnets or hinge, in which case immediate cleaning with a dry brush and compressed air is necessary to avoid mechanical wear of the parts.
