The Xiaomi Mi Band’s silicone straps (including the Mi Band 4/5/6/7, Smart Band Pro and Watch S1) are a practical accessory, but they inevitably become contaminated over time. Sweat, dust, cosmetics and bacteria enter the material’s micropores, causing unpleasant odor, skin irritation and even premature wear of the strap. Studies show that up to 10,000 colony-forming units of bacteria accumulate on the wearable devices’s surface after 2 weeks of use – more than on the public toilet seat.
In this article, 7 proven cleaning methods (from fast home methods to deep disinfection), a comparative table of the effectiveness of tools, as well as unique recommendations for the care of Xiaomi straps, taking into account their design features (for example, the presence of metal latches or touch zones).
Why Xiaomi silicone strap smells and sticks: 3 main reasons
The unpleasant smell and stickiness of the strap is not just an aesthetic problem, but a signal of the active reproduction of microorganisms. Unlike leather or tissue counterparts, silicone does not absorb moisture, but its porous structure becomes the ideal environment for:
- 🦠 Bacteria (Staphylococcus, Propionibacterium) - feed on sweat and dead skin cells, secreting hydrogen sulfide (a source of "rotten" smell).
- 🍄 Fungi (Malassezia) - cause itching and peeling of the skin under the bracelet.
- 🧴 Remains of cosmetics (creams, antiperspirants) - form a sticky film that attracts dust.
Interesting fact: in laboratory tests, Xiaomi Mi Band 6 straps after a month of socks showed 2 times more bacteria than Apple Watch straps of the same user. This is due to the hydrophobic coating of Xiaomi silicone, which is worse repels sweat, but better masks contamination visually.
⚠️ Attention: If there are red spots or rashes under the bracelet, immediately remove the device and treat the skin with chlorhexidine 0.05%. Xiaomi silicone straps with a textured surface (for example, the Mi Band 7 Pro) accumulate bacteria faster than smooth ones!
Preparing the strap for cleaning: 4 mandatory steps
Before cleaning, disconnect the strap from the bracelet body - most Xiaomi models (except the Watch S1 Active) have removable straps with fast-release latches.
Turn off the bracelet from charging and turn it off (press the 5 seconds button before vibration)
Carefully press the metal latch on the back of the strap and pull it sideways.
Check the integrity of the silicone surface – cracks or tears require a belt replacement

For models with an integrated heart rate sensor (such as the Xiaomi Smart Band 7 Pro), avoid moisture on the touch zone – it is sealed, but aggressive detergents can damage the infrared coating of the sensor.
Tip: If the strap is heavily contaminated, soak it in warm water with baking soda (1 tbsp per 200 ml) for 15 minutes, it will soften the sediments. But don't use hot water: Xiaomi silicone loses elasticity at temperatures above 60°C.
7 Ways to Clean a Band: From Express Method to Deep Disinfection
The choice of method depends on the degree of contamination and the type of strap. Smooth silicone models (Mi Band 4/5) will be suitable for gentle methods, and textured (Mi Band 6/7) or straps with metal inserts (Watch S1) will require special tools.
| Method | Suitable for | Time. | Effectiveness against smell | Risk of damage |
|---|---|---|---|---|
| Soap solution | Light pollution, all models | 5-10 minutes | ⭐⭐ | Low. |
| Toothpaste + brush | Blackening, rough straps | 15 minutes | ⭐⭐⭐ | Medium (abrasives) |
| Vinegar solution (1:1) | Fungus, persistent smell | 30 minutes | ⭐⭐⭐⭐ | Tall (corrodes glue) |
| Alcohol (70%) | Disinfection, smooth straps | 5 minutes | ⭐⭐⭐ | Low. |
| Ultrasonic bath | Deep cleaning, all models | 10 minutes | ⭐⭐⭐⭐⭐ | Medium (vibration) |
Express method (for daily cleaning):
- Wet the soft cloth in warm water with liquid soap (pH 5.5-7).
- Wipe the strap on both sides, paying attention to the joints with the metal.
- Wash under running water and dry vertically (not on a battery!).
Deep cleaning (1 time per month):
- Immerse the strap in a solution of vinegar 9% + water (1:1) for 20 minutes.
- Clean with a brush with soft bristles (such as a baby tooth).
- Wash and treat 70% with isopropyl alcohol for disinfection.
What to do if the strap turns yellow?
⚠️ Warning: Never use acetone, gasoline or chlorine bleach to clean Xiaomi straps, which break down the silicone coating and cause microcracks. Also avoid hard sponges (such as metallic ones for dishes): They erase the factory texture of the strap, which causes it to "stick" to the skin.
How to Clean a Metal Band (For Xiaomi Watch S1, Smart Band Pro)
Straps with metal fasteners or decorative inserts require a special approach, the main problem is the corrosion of metal when in contact with aggressive solutions. S1 Smart Band Pro:
- 🚫 Prohibited: soak the strap whole (metal can oxidize).
- ✅ Allowed: Clean silicone areas separately, avoiding moisture on the metal.
- 🔧 Secret: to clean joints, use cotton swabs dipped in alcohol.
Instructions for metal straps:
- Wipe the silicone parts with a solution of baby shampoo (1 drop per 100 ml of water).
- Treat the metal elements with a dry microfiber with a drop of oil to care for the watch (prevents darkening).
- To remove plaque in the latch slots, use a toothpick wrapped in a thin fabric.
💡
After cleaning the Xiaomi Watch S1 strap, apply a thin layer of petroleum petroleum oil to the metal parts – this will prevent dark spots from sweat.
How to dry a strap: 3 mistakes that spoil silicone
Improper drying is the main reason Xiaomi straps lose shape and start cracking.
- 🔥 Drying on a battery or in direct sunlight – silicone becomes brittle and UV rays accelerate yellowing.
- 🧺 Hang the strap folded - leads to deformation (especially important for wide straps Mi Band 7 Pro).
- 💨 Use a hair dryer – hot air destroys the hydrophobic coating of silicone.
Proper drying:
- Wet the strap with a paper towel (don't rub!).
- Hang it on a plastic clasp in a well-ventilated place (for example, on a balcony in the shade).
- To speed up the process, use the fan at minimum power (at least 50 cm distance).
The drying time depends on the thickness of the strap:
- Mi Band 4/5 (thin silicone) 1-2 hours
- Mi Band 6/7 (textured) – 3-4 hours
- Watch S1 (with metal inserts) - up to 6 hours.
💡
Xiaomi silicone straps cannot be dried in closed containers (for example, in plastic boxes) - this provokes the development of mold due to condensation.
Prevention: how to extend the life of the strap in 2 times
The average life of Xiaomi silicone strap is 12-18 months, but with proper care it can be increased to 3 years.
- 🚿 Remove your bracelet before shower – chlorinated water and shampoos destroy silicone.
- 🏋️ Wash the strap with a wet wipe after exercise – sweat contains salts that corrode the material.
- 🌡️ Avoid extreme temperatures – do not leave the bracelet in the car in summer or in the cold.
- 🧴 Apply the cream 30 minutes before wearing the bracelet – this reduces the stickiness of the strap.
For models with touch buttons (Mi Band 7 Pro), use a protective film on the screen - this reduces the number of touches on the strap with dirty fingers. Also, once a week, treat the strap with antibacterial wipes for equipment (for example, Apple Polishing Cloth).
An interesting life hack: if the strap starts to creak, apply a silicone grease in a spray on the inside (sold in auto parts stores) to restore the smoothness of the material and eliminate the unpleasant sound.
When cleaning is useless: 4 signs that it is time to change the strap
Even with perfect care, Xiaomi silicone straps wear out over time. Replace the strap if you notice:
- 🔍 Microcracks – they accumulate dirt that can not be cleaned.
- 🧲 Loss of elasticity - the strap is not fixed on the wrist, slides.
- 🤢 Persistent smell that does not clear even after disinfection with alcohol.
- 🎨 Color change (blue, greening) – a sign of chemical destruction of the material.
The original Xiaomi straps cost from 300 to 1500 rubles (depending on the model), but you can save money by choosing compatible analogues from Amazfit or Huawei.
- Mi Band 4/5/6 - 18 mm
- Mi Band 7/7 Pro – 20 mm
- Watch S1 - 22 mm.
⚠️ Note: When buying straps on AliExpress, pay attention to the material - cheap silicon fakes often contain PVC or rubber, which cause allergies and crack after a month. Xiaomi's original straps have laser engravings on the inside of the logo.
