Xiaomi Mi Band fitness bracelets have become an integral part of the daily lives of millions of users β they monitor activity, monitor sleep and even alert calls. But constant contact with skin, sweat, dust and cosmetics turn the device into a breeding ground for bacteria after a few days of use. Studies show that 10 times more microbes accumulate on the surface of wearable gadgets than on the toilet seat, and 9 out of 10 owners clean the bracelet incorrectly β use aggressive detergents, soak the case or ignore the strap, leading to damage to the device or skin irritation.
In this article, we will discuss 7 safe cleaning methods for all Mi Band models (from Mi Band 2 to Mi Smart Band 8 Pro), including the processing of silicone, leather and fabric straps, as well as delicate cleaning of sensors and connectors. You will learn what tools you can use (and what to avoid!), how to remove persistent contamination without risking damage to electronics, and why standard washing under the tap can reduce the life of the bracelet by 30%.
Why Xiaomi Mi Band bracelet should be cleaned regularly
According to dermatologists, 78% of skin irritations under fitness bracelets are caused by accumulation of sweat, dead cells and bacteria, and users often ignore cleaning until visible problems appear:
- π¦ Bacterial pollution: On a silicone strap after 3 days of wearing, up to 10 forms^6 CFU / cm2 microorganisms (according to SanPiN standards, the safe level is not more than 500 CFU / cmΒ²).
- π Contact oxidation: Sweat contains salts and fats that lead to corrosion of charging connectors (especially relevant for the Mi Band). 4/5 open-contact).
- π Sensor failures: Dirt on heart rate sensor distorts readings by 15-20%, and contaminated accelerometer can misread steps.
- π¨ Allergic reactions: Low quality silicone (in fakes) combined with later causes dermatitis in 12% of users.
Xiaomi engineers recommend cleaning the bracelet every 2-3 days when used actively (sports, showers, sleep). However, even weekly alcohol treatment reduces the number of bacteria by 99.9% if done correctly.
What not to do when cleaning the Mi Band: 5 critical mistakes
Before we get to cleaning methods, we'll look at the things that are forbidden to do that can actually make the bracelet go wrong, and even the most experienced users make these mistakes.
β οΈ Warning: If your Mi Band has open charging contacts (Mi Band 3-7 models), avoid getting liquid into the connector. moisture oxidizes the contacts for 24-48 hours, after which the bracelet stops charging.
- π« Soaking the case: Even if the bracelet has protection 5 ATM (Like Mi Band. 6/7), Long-term exposure to water erodes the adhesive compounds inside.
- π₯ Boiling or hot water: Temperature above 60Β°C deforms silicone and plastic, and also destroys waterproof gaskets.
- π§΄ Abrasives: Powders, soda paste, or hard brushes scratch the screen and sensors, leading to false positives.
- π Use of alcohol >70%: Concentrated alcohol dissolves the protective coating of the display and makes the plastic brittle.
- βοΈ Drying in direct sunlight: UV radiation destroys silicone straps, making them sticky and brittle.
If you have already made one of these mistakes, check the bracelet for signs of damage:
| Symptoms. | Possible cause | Decision |
|---|---|---|
| Bracelet not charging | Oxidation of contacts from moisture | Clean contacts with a cotton swab dipped in vinegar (see section 4) |
| The screen has become cloudy | Scratching or corroding the protective layer with alcohol | Apply protective film or replace the display |
| The strap is crumbled. | Exposure to high temperatures or UV rays | Replace the band (original cost from 300) β½) |
| Heart rate sensor shows error | Dirt on the sensor or glass damage | Clean the sensor with a soft napkin with isopropyl alcohol |
Method 1: Quick cleaning of silicone strap (daily care)
This method is suitable for preventive cleaning and removal of fresh contaminants (sweat, dust, cream).
Soft toothbrush (new not to use - bristles too hard)|Warm water (not above 40)Β°C)|Liquid soap without fragrance (for example, children's soap)|Microfibre wipe (from the set for glasses)|Cotton swabs (for hard-to-reach places)-->
Step-by-step:
- Remove the bracelet capsule from the strap (on Mi Band 4-8 models, press the button on the back).
- Wet your toothbrush in soapy solution (1 drop of soap per 100 ml of water) and gently clean the strap on both sides, paying attention to the grooves of the attachment.
- Wash the strap under running water, avoiding the jet hitting the body of the bracelet.
- Dry the strap with a microfiber, then leave it in the air for 15 minutes (don't use a hair dryer!).
- Wipe the body of the bracelet with a wet wipe for electronics (without alcohol).
π‘
If the strap starts to smell, add 1-2 drops of hydrogen peroxide (3%) to the soap solution, which will kill bacteria and eliminate the smell without harming the material.
For models with touch screen (Mi Band) 5/6/7/8) After cleaning, check the sensitivity of the display: sometimes soapy wiring leaves a film that prevents swipes from working. If the screen becomes less responsive, wipe it with a napkin dipped in distilled water.
Method 2: Deep cleaning of the strap from old dirt and sweat
If the strap has become sticky to the touch, yellowed or covered with black stripes (especially relevant for the Mi Band). 2/3), It's going to take a more radical approach. 95% pollution, but requires caution.
Do not use this method more than 1 time a month - aggressive substances reduce the life of silicone.
| Remedy. | Proportions | Time of exposure | What models are suitable for |
|---|---|---|---|
| vinegar + water | 1:1 | 10-15 minutes | All models. |
| Citric acid | 1 tsp per 200 ml of water | 5 minutes. | Only Mi Band 4-8 (with 5 protection) ATM) |
| Toothpaste (no abrasives!) | β | 2-3 minutes | All models (except fabric straps) |
| Special wipes for electronics | β | β | All models (the safest option) |
Instructions for acetic solution (the most effective method):
- Remove the strap from the bracelet capsule.
- Immerse the strap in a solution of vinegar and water for 10 minutes.
- Clean with a brush, paying attention to the grooves and the inside.
- Wash thoroughly with water and dry for at least 1 hour (the vinegar odor should completely weather).
β οΈ Note: If you have a Mi Smart Band 7 Pro or Mi Band 8 Pro with a metal body, vinegar can cause aluminium to darken. For these models, use only citric acid or specialized wipes.

Method 3: Cleaning the case and sensors without risk of damage
The body of the bracelet requires a special approach - here are the heart rate sensor, the accelerometer and (in new models) the SpO2 sensor. Incorrect cleaning can lead to false readings or breakage.
What you need:
- π§΄ Isopropyl alcohol (70%) β the best remedy for electronics.
- π¨ Soft brush (for example, for watercolors) - for cleaning connectors.
- π§» Whipless wipes (for glasses or equipment).
- π Cotton sticks - for hard-to-reach places.
Step-by-step algorithm:
- Disconnect the strap from the body (if the model is collapsible).
- Wet the napkin in isopropyl alcohol and gently wipe the front panel (with display) and the back side (with sensors).
- To clean the charging contacts, use a cotton swab dipped in alcohol. Movements should be light, without pressing.
- If dirt has accumulated between the body and glass, use a brush soaked in alcohol.
- Allow the bracelet to dry for at least 30 minutes before connecting to the charger.
For models with a physical button (Mi Band) 2/3) Notice the gap around the button, which is often where dirt accumulates. Use a toothpick wrapped in a wet wipe to carefully remove the contamination.
π‘
Never use wet hand wipes to clean your case β they contain fats and fragrances that leave the film on the sensors and can cause allergies.
Method 4: Removal of oxidation from charging contacts
If the bracelet is not charging well or is not recognized by the charger, the problem is most often oxidized contacts, which is suitable for all Mi Band models except the Mi Band 8 Pro (it has magnetic charging).
Signs of oxidation:
- π Charging is interrupted or is jerking.
- β‘ Bracelet shows "charge" but battery percentage does not increase.
- π Contacts darkened or covered with a green coating.
How to clear contacts:
- Moisten the cotton swab in table vinegar (9%).
- Gently wipe the contacts without pressing for 10-15 seconds.
- Remove vinegar residues with a dry cotton swab.
- Repeat the procedure with isopropyl alcohol to neutralize the acid.
- Allow the bracelet to dry for 1 hour before connecting to charging.
β οΈ Attention: If the bracelet doesn't charge after cleaning, check the charger. Often the problem is the oxidation of the contacts at the dock, not the bracelet.
Method 5: Cleaning leather and fabric straps
Leather straps (for example, for Mi Band 6) NFC) And the fabrics, the Mi Band 7 Pro, require special care, and they absorb more sweat and dirt than silicone, but they don't tolerate moisture.
For leather straps:
- π§Ό Use special wipes for the skin or wet microfiber.
- π§΄ Apply some glycerin soap on a napkin and gently wipe the strap.
- βοΈ Dry at room temperature, avoiding direct sunlight.
- π‘οΈ Once a month, wax your skin (extends service life by 30%).
For fabric straps:
- Remove dust with a soft brush (for example, for clothing).
- If you have severe contaminants, use foam to clean the fabric (apply for 5 minutes, then remove with a wet wipe).
- Never wash in a typewriter β it deforms the fasteners!
If the fabric strap began to spread around the edges, carefully trim the threads and treat the edge with a transparent nail polish - this will prevent further shedding.
Method 6: Disinfection of the bracelet from bacteria and viruses
In epidemics or if the bracelet is worn by several people (for example, in the family), regular cleaning is not enough β it requires disinfection. According to research, the coronavirus can persist on plastic for up to 72 hours, and staphylococcus β up to a week.
Safe disinfectants:
| Remedy. | Concentration | Time of exposure | Notes |
|---|---|---|---|
| Isopropyl alcohol | 70% | 1 minute | The Best Option for Electronics |
| chlorhexidine | 0,05% | 2-3 minutes | He doesn't leave a divorce. |
| Hydrogen peroxide | 3% | 5 minutes. | Only for the strap (not for the body!) |
| UV lamp | β | 10-15 minutes | Effectively kills 99.9% of bacteria |
How to disinfect:
- Remove the strap from the body.
- Wash the body with a wipe with 70% alcohol (for the Mi Band 8 Pro, use chlorhexidine - it does not damage the metal).
- Load the strap in a chlorhexidine solution for 3 minutes (for silicone) or wipe with a napkin (for skin/tissue).
- Dry in the air for at least 2 hours.
Any UV lamp (such as a manicure) is suitable for UV disinfection, and place the bracelet 5-10 cm from the lamp and irradiate for 10 minutes on each side.
Method 7: Ultrasonic cleaning (for advanced cases)
If the bracelet has not been cleaned for more than 6 months and the strap is covered with black plaque or mold, an ultrasound bath will help, which removes contaminants from the silicone pores and restores the original appearance.
What you need:
- π Ultrasonic bath (you can buy for 1,500β2,000) β½ Or use a bath for jewelry).
- π§Ό Special solution for ultrasonic cleaning (or a mixture of water and glass washing products in a ratio of 10:1).
- β± Timer.
Step-by-step:
- Remove the strap from the bracelet body.
- Place the strap in the bath with the solution.
- Set the time of 3-5 minutes and the temperature is not higher than 40Β°C.
- After cleaning, wash the strap with water and dry for 24 hours (ultrasound knocks moisture deep into the pores of the material).
β οΈ Warning: Do not clean the bracelet body in an ultrasonic bath - vibrations can damage internal connections and solder off contacts!
This method is particularly effective for straps with a textured surface (such as the Mi Band 7 Pro), where dirt is clogged into micropores.
Prevention: how to prolong the purity of the bracelet
To avoid resorting to radical cleaning methods, follow simple rules:
- πΏ Remove the bracelet in front of the shower (even if it is waterproof). Chlorine and shampoo spoil silicone.
- π¦ Wash the bracelet with a wipe after training or active sweating.
- π Change the straps every 6-12 months (silicone loses elasticity).
- π Wear the bracelet not tightly - a gap of 1-2 mm between the strap and the skin reduces sweating.
- π§΄ Apply the cream 30 minutes before wearing the bracelet (fats from the creams attract dirt).
For models with NFC (Mi Band 6 NFC, Mi Band 7 Pro: Avoid contact with magnets and metal surfaces β this can disrupt the chip.
π‘
If you are playing sports, buy a second strap and change them every 3 days. This will extend the life of both straps by 2 times.
