How to properly clean the strap from Xiaomi smart watches: from poto fat spots to mold

Why does Xiaomi’s smartwatch strap require regular cleaning?

Xiaomi’s smartwatch strap is not just an accessory, but a zone of constant contact with the skin. Sweat, skin fat, dust and even residues of creams create the perfect environment for bacteria to multiply. According to dermatologists, the surface of silicone bracelets accumulates up to 10,000 microbes per 1 cm2 after 2 weeks of wear — more than on a smartphone screen! 68% of users never wash the straps, limiting themselves to wiping the case.

The consequences of neglect of hygiene are manifested quickly: from skin irritation and unpleasant smell to the appearance of black spots of mold on the inside of the strap (especially important for Mi Band models). 5/6 Leather and fabric variants suffer from deformation and loss of color, and metal links become dim due to oxidation. Proper cleaning not only prolongs the life of the accessory, but also prevents dermatitis - this is warned even in the instructions for the Xiaomi Watch. S3 Pro and Mi Band 8.

This article provides 7 proven cleaning methods for all types of straps (silicone, leather, metal, fabric), including emergency measures against mold and persistent contaminants, and a table of materials compatibility so that you do not spoil the bracelet in the first 5 minutes of cleaning.

What straps Xiaomi uses: materials and their features

Xiaomi has four basic materials straps in its devices, each requiring a different cleaning approach, and consider their characteristics and weaknesses:

• 🧪 silicone (TPU) — The most common variant for the Mi Band and budget Xiaomi Watch, water-resistant but absorbs sweat fat deposits, gets sticky over time, fears alcohol and acetone!
• 🐄 Natural/artificial leather – used in premium models (Watch) S3, Mi Band 7 Pro. Sensitive to moisture, deformed when drying improperly, can be covered with white plaque from sweat.
• 🔗 Metal (stainless steel, aluminum) - straps for Xiaomi Watch 2 Pro and limited editions. resistant to corrosion, but accumulate dirt in the joints of the links. Require polishing.
• 🧵 Tissue (nylon, polyester) - found in the sporty version (Mi Band 6) NFC). It gets dirty quickly, absorbs smells, but is easily erased.

Important: Xiaomi often changes material suppliers even within the same model. For example, the 2022 and 2023 Mi Band 7 straps differ in the composition of silicone - newer less porous but more prone to electrification. Check the labeling on the inside of the bracelet: if there is a label TPU-95A, It is a soft silicone that cannot be rubbed with hard brushes.

Preparation for cleaning: what can and can not be done

Before proceeding with the procedure, unplug the strap from the watch body – almost all Xiaomi models (except the Watch). S1 Pros with a non-removable bracelet allow you to do this without tools. Press the lock button on the inside and pull the strap aside. If there are no buttons, use a plastic blade (such as from a mediator) to fit the mount.

General rules for all types of straps:

• ❌ Do not use hot water (above 40)°C - This deforms silicone and skin.
• ❌ Avoid abrasives (baking soda, powders, hard sponges) – they scratch the surface.
• ❌ Do not dry the straps with a hairdryer or on a battery - this leads to cracking of materials.
• ✅ For drying, use paper towels or cotton fabric.

Disconnect the strap from the body

Check the material (marking on the inside)

Prepare a soft brush (dental or makeup)

Prepare a basin with warm water (no more than 40)°C)

Choose the tool on the compatibility table-->

⚠️ Warning: If the strap has electronic components (such as the heart rate sensor in the Mi Band 8 Pro), avoid being completely immersed in water!

7 Ways to Clean Xiaomi Band at Home

The choice of method depends on the degree of contamination and material, and below are step-by-step instructions from the most gentle to the "heavy artillery" for old spots.

1. Soap solution (universal method for all materials)

Suitable for weekly preventive cleaning.Use baby soap or dishwashing product without fragrance (e.g. Fairy or AOS).

1. Dissolve 1 tsp. soap in 200 ml of warm water.
2. Load the strap for 10-15 minutes (except leather - only wipe them with a moistened sponge!).
3. Clean the hard-to-reach places (grooves, holes for fastenings) with a soft brush.
4. Wash under running water and dry vertically (for example, hanging on a pinch).

2. acetic solution (against smell and bacteria)

Effective for silicone and fabric straps if you have a persistent smell. Vinegar (9%) kills up to 80% of microbes, but not suitable for skin and metal!

Mix water and vinegar in a ratio of 3:1, soak the strap for 20 minutes. To enhance the effect, add 1 drop of tea tree essential oil - it has antifungal properties. After the procedure, thoroughly rinse with water to avoid skin irritation when wearing.

Alcohol wipes (express method)

Use isopropyl alcohol (70%) or wipes for machinery. Suitable for metal and silicone straps, but no more than 1 time a month - alcohol dries the material. Wipe the surface with a napkin, paying attention to the joints of the links. For Xiaomi Watch 2 Pro with sapphire glass, you can use alcohol to clean the case, but avoid getting on the strap of natural leather.

4. Toothpaste (for polishing metal and silicone)

Unexpectedly, but white toothpaste without granules (for example, SPLAT Whitening is great at removing the darkening from the metal straps and bringing back the shine to the silicone. Apply the paste on the brush, brush the strap in circular motions, wash it off in 5 minutes!

5. Baking soda (against black mold spots)

If the strap has dark mold spots (a common problem for the Mi Band 5 after wearing in humid climates), make a gruel of soda and water (1:1), apply for 10 minutes, then rinse. To enhance the effect, add a few drops of hydrogen peroxide (3%). After soda treatment, be sure to apply a thin layer of vaseline to the silicone - this will restore the elasticity of the material.

6. Lemon juice (lightening of yellowed silicone)

Silicone straps turn yellow over time due to oxidation. Lemon juice will help to return the original color: wipe the surface with it, leave it for 5 minutes under direct sunlight (UV radiation enhances the bleaching effect), then rinse it. The method does not work for deep contaminants, but brightens 1-2 tones.

7. Special means (for leather straps)

Clean your natural skin with only special formulations (e.g. Collonil Lederpflege or Saphir Renomat). Apply it on a cotton-coat disc, wipe the strap, then apply skin conditioning. For artificial skin, a mixture of water and glycerin (1:1) will do. Never use alcohol or vinegar - they destroy fibers!

💡

For silicone straps Xiaomi Mi Band the best combination – soap solution + vinegar 1 time per week. This removes 99% of bacteria and prevents the appearance of odor.

How to remove persistent contamination: mold, potassium stains, paint

If conventional methods don't work, you'll have to use heavy artillery, but remember, aggressive means reduce the life of the strap by 30 to 40 percent.

Mold on silicone

Black mold spots appear when stored in a wet room (for example, if you dry a strap in the bathroom).

1. Prepare the solution: 1 tbsp hydrogen peroxide (3%) + 1 tbsp water + 1 tsp. soda.
2. Apply the mixture on the spots with a cotton swab, leave for 30 minutes.
3. Rub it with a soft brush and rinse it off. Repeat it if necessary.

After processing, be sure to dry the strap for 24 hours - residual moisture will provoke the reappearance of mold.

Potassium deposits on the skin

On leather straps, sweat leaves a white coating that cannot be removed with soap. Use a solution of water and ammonia (10:1):

1. Wet the cotton disc in solution.
2. Clean the contaminated areas (don’t press hard!).
3. Apply skin conditioning in 1 hour.

Paint or ink

If the strap is ink (for example, from a printer) or ink, use vegetable oil:

1. Apply the oil on the stain, leave for 10 minutes.
2. Wash it with a paper napkin.
3. Wash it with soapy solution.

For silicone, a melamine sponge is also suitable, but it cannot be used on skin and metal.

⚠️ Note: If the Xiaomi Watch strap S3 magnetically fastened, do not use metal brushes for cleaning - they will magnetize the mechanism, and the fastener will cease to fix!

How to prolong the life of a strap: pollution prevention

Compliance with simple rules will reduce the cleaning frequency by 2-3 times:

• 🚿 Take off your watch in front of a shower, pool or sauna – chlorine and high heat destroy silicone.
• 🧴 Apply the cream 10 minutes before putting on the clock – it will reduce the amount of fat on the strap.
• 🌞 Dry the strap outdoors after sweating (for example, while charging the clock).
• 🔄 Alternate straps – if you wear one bracelet constantly, buy a spare one (original ones cost from 500) ₽).

For silicone straps, the Mi Band can use a protective spray (such as Apple Polishing Cloth or Whoosh!) to create a thin film that repels dirt. Apply the spray 1 time per month, avoiding sensors.

If you are a sportsman, choose antibacterial coated straps (such as the Xiaomi Mi Band 7 Pro in the Antibacterial Strap trim), which contain silver ions that inhibit the growth of microbes.

💡

Store spare straps in a sealed bag with silica gel (a bag from a shoe box) - this will prevent mold from appearing during prolonged storage.

Frequent mistakes when cleaning Xiaomi straps

Even the most experienced users sometimes ruin the straps because of the wrong actions. TOP-5 errors and their consequences:

1. Using a toothbrush with hard bristles → scratches on silicone, erasing paint from metal.
2. Drying by a hairdryer → cracking of the skin, deformation of silicone.
3. Application of bleach for fabric straps → fibre destruction, loss of color.
4. Long-term soaking of leather straps → stratification of the material, the appearance of a white plaque.
5. Use of the WD-40 metal-strap → leaves a greasy film that attracts dirt.

Another common problem is trying to bleach yellowed silicone with chlorine, which not only doesn't help, but also makes the material brittle. Instead of chlorine, use hydrogen peroxide (3%) + soda (recipe described above).

If you accidentally used a prohibited product, immediately rinse the strap under running water and apply a care product:

• For silicone — WD-40 Specialist Silicone Lubricant (thin layer).
• The skin is the Bick 4 Leather Conditioner.
• For metal, Autosol Metal Polish.
