How to properly wash the Xiaomi Mi Band bracelet: from sweat to old dirt

Xiaomi Mi Band fitness bracelets (including Mi Band 4/5/6/7 and Smart Band 8) have become an integral part of the daily lives of millions of users, tracking pulse, steps, sleep and even blood oxygen levels — but they are in daily contact with sweat, dust, creams and bacteria. After a month of active use, the strap can become covered with sticky plaque, and under the body, black dirt that cannot be removed with a dry napkin.

Compounding the problem, improper cleaning can damage waterproof pads, sensors, or displays, such as aggressive solvents (acetone, high-concentration alcohol) destroy the silicone strap, and rigid brushes scratch glass. In this article, the only proven cleaning algorithm approved by Xiaomi service centers, taking into account the features of each bracelet model.

Why Xiaomi Mi Band bracelet gets dirty quickly: 3 main reasons

Even with careful use, the fitness tracker loses its original appearance after 2-3 weeks.

• 💦 Sweat and skin fat: During exercise or sleep, the pores release fluid that mixes with dead epidermis cells and forms a sticky film on the strap and back panel.
• 🧴 Cosmetics and creams: particles of moisturizers, sun lotions and deodorants penetrate the silicone micropores, leaving whitish divorces.
• 🦠 Bacteria and fungi: According to studies, up to 10 devices are found on the surface of wearable devices after a week of use^6 CFU/cm2 microorganisms (including staphylococcus).

Especially vulnerable models with textile straps (Mi Band 6 NFC, Smart Band 7 Pro): they absorb moisture like a sponge, and dry them completely without deformation is almost impossible.

What can not be used for cleaning: 5 prohibited means

Before you start cleaning, remember: Xiaomi Mi Band is IP68-proof electronics (for most models), but that doesn’t mean it can be washed under running water or soaked in solutions.

⚠️ Attention: Using ultrasonic baths to clean the bracelet will detach the waterproof pads and get moisture on the board. Warranty centers refuse repairs for such damage.

• 🔥 Hot water (above 40)°C: warps silicone and sensor adhesives.
• 🧪 Abrasive powders (baking soda, tooth powder): scratch glass and anodized coating of the body.
• 🧴 Aggressive household chemicals (Domestos, White): destroys seals and leaves toxic residues.
• 🔪 Metal brushes/knives: Even a soft dishbrush leaves micro-scratches on the display.
• ☀️ Direct Sunrays for Drying: UV Radiation Accelerates Silicone Aging, Making It Fragile.

Also avoid alcohol-containing wipes to clean the display – they remove the oleophobic coating, which is why the screen begins to collect fingerprints.

How to wash the Xiaomi Mi Band strap: step-by-step instructions

The strap is the most problematic part of the bracelet, and its porous structure absorbs dirt, and constant contact with the skin accelerates the reproduction of bacteria, and the cleaning methods depend on the material:

For silicone straps (the most common option), act as follows:

Remove the strap from the bracelet body|Prepare the solution: 1 glass of warm water + 2 drops of liquid soap|Soak the strap for 10-15 minutes|Wash with a soft bristle toothbrush|Wash under a weak stream of water|Dry in air (at least 2 hours)-->

If the strap is yellowed or covered with a sticky coating, use baking soda:

1. Mix the soda with water to a gruel state.
2. Put it on the strap for 5 minutes.
3. Rub your fingers carefully (without pressing!).
4. Wash the remains with a wet wipe.

💡

To remove the persistent odor, soak the strap in a solution of water and vinegar (1:1) for 20 minutes, then rinse. Vinegar kills bacteria, but does not damage silicone.

Cleaning the case and sensor: how not to damage the electronics

The body of the bracelet requires special care: there is a heart rate sensor, an accelerometer and charging contacts, moisture entering these areas is fraught with corrosion or short circuit.

1. Unplug the strap (if the model allows). In Mi Band 4/5, pull the strap to the side, in Mi Band 6/7/8, press the button on the back.
2. Wipe the body with a wet wipe made of microfiber, soaked in a solution of water and isopropyl alcohol 70% (proportion 1: 1).
3. Clean the sensor with a cotton swab dipped in the same solution, moving from center to edge.
4. Wipe the charging contacts with a dry cotton swab (moisture can not be used here!).

For models with a display (Mi Band 5/6/7/8), use special wipes for smartphone screens. Don't press hard - the display is mounted on a thin plume that can be torn off.

⚠️ Warning: If the bracelet is no longer synced with your phone after cleaning, check the charging contacts for oxide film (green coating), remove it with a pencil eraser, then wipe it with alcohol.

How to remove black dirt from under the case and buttons

The most challenging task is to clear the gaps between the body and the glass, as well as the area around the button (in the Mi Band 4/5 models), where a mixture of sweat, dust and dead cells accumulates, forming a black border, which can be removed in two ways:

Method 2: Vacuum cleaning (for models without buttons, such as Mi Band 6/7):

1. Take a vacuum cleaner with a narrow nozzle (or a car compressor on the blower).
2. Set minimum power.
3. Bring the nozzle to the gap at a distance of 1-2 mm.
4. Short-term impulses (2-3 seconds) blow out the dirt.

If dirt doesn't lend itself, use ultra-thin cotton swabs (such as to clean the ears of newborns), soak them in alcohol and gently scrolle them in the problem area.

💡

Never use toothpicks or needles to clean the seams – they puncture waterproof pads, which leads to moisture getting inside the case.

Disinfection of the bracelet: how to kill bacteria and fungi

Conventional cleaning removes visible dirt, but does not destroy microorganisms.

• 🦠 Ultraviolet lamp: place the bracelet under the UV lamp on 10–15 The method kills. 99.9% Bacteria, but not suitable for models with AMOLED-Display (Mi Band) 6/7/8 — pixel-burn).
• 🧼 Chlorhexidine 0.05%: wipe the body and strap with a napkin dipped in solution.
• ☀️ Sunlight: Leave the bracelet on the windowsill for 4-6 hours. UV rays naturally destroy microbes.

For sensor models SpO₂ (Mi Band 5/6/7) After disinfection, check the accuracy of the readings: run the oxygen saturation test and compare it with the pulse oximeter. ±2%, Repeat cleaning of sensor contacts.

How to wash the Xiaomi Mi Band bracelet from paint, glue and other persistent contaminants

Sometimes the bracelet is stained not only with sweat, but also with paint (for example, from hair or clothing), glue (from stickers) or ink.

⚠️ Warning: To remove the permanent marker from the body of the Mi Band, use a melamine sponge, but only on a matte surface! on glossy cases (Mi Band 7 Pro), it leaves micro-scratches.
