Xiaomi's fitness band is not just an accessory, it's part of a device that comes in contact with skin and then external contaminants every day. Even if you wear the Mi Band 6, Mi Smart Band 7 Pro or the new Xiaomi Band 8, over time, the strap loses its original appearance: yellowness, unpleasant smell, sticky plaque or microcracks, while improper cleaning can spoil the material - the silicone will break, the skin will crack, and the fabric strap will shed.

In this article, we will discuss 7 proven ways to clean Xiaomi fitness bands, from budget home remedies to professional methods. You will learn which materials can be washed under running water and which require a delicate approach, what is different from the care of silicone, leather and fabric straps, and how to avoid the typical mistakes that make the bracelet become unusable. For convenience, we have compiled a table of compatibility of materials and cleaning products – it will help you choose the best option without experimentation.

Why Xiaomi’s fitness bracelet strap gets dirty and stinks

The main cause of pollution is natural skin discharge, and during exercise or hot weather, sweat accumulates under the strap, which contains salts, fats and bacteria, and if you do not clean the bracelet regularly, these substances react with the material, causing:

• 🟡 Yellowness - especially noticeable on white and light straps made of silicone.
• 🤢 Bad smell is the result of the reproduction of bacteria (most often Staphylococcus and Corynebacterium).
• 🧴 Sticky plaque – a mixture of sebum and dust, which attracts even more dirt.
• 🔍 Microcracks – appear due to drying up of the material (especially in cheap replicas).

The second cause is external pollution: dust, hand cream, cosmetics or even food particles (if you forget to remove the bracelet while eating).For example, the Mi Band 5 with a fabric strap quickly absorbs greasy spots, and the leather Xiaomi Watch models. S1 They may be covered with white coating from contact with water.

⚠️ Note: If you are wearing a bracelet 24/7, brush the strap at least less often 1 Ignoring care not only leads to aesthetic problems, but also to skin irritation (dermatitis, itching, redness).

How to determine the material of the strap: silicone, leather or fabric

Before cleaning, it is important to understand what your strap is made of. Xiaomi has three main types of materials:

If you are not sure about the material, check:

• 📦 Box or documentation – usually listed in the box.
• 🔍 Marking on the back of the strap (e.g, "TPU" — thermoplastic polyurethane, a type of silicone).
• 💡 Price – leather straps are more expensive than silicone.

7 Safe Ways to Clean Xiaomi’s Strap

The choice of method depends on the material and the degree of contamination, and we have sorted the methods from the most gentle to aggressive (use the latter only in extreme cases!).

1. Soap solution (universal method)

Suitable for all types of straps except leather straps with open seams. Use baby soap or dishwashing product without fragrances (such as Fairy or Fresh.) AOS).

Remove the bracelet capsule from the strap (if the model is collapsible)|Pour warm water (not hot!) into a bowl|Add 2-3 drops of soap and foam|Load the strap for 10-15 minutes|With a soft toothbrush, clean hard-to-reach places (perforation, clasp)|Rinse under running water|Dry in air (not on a battery!)|Return the capsule to its place after drying out completely.-->

For silicone straps, you can use a soft bristling toothbrush, which is good at removing dirt from micropores. For fabrics, you'd better use a cotton-coated disc.

⚠️ Note: Do not rub the strap with a sponge for dishes - its hard fibers scratch silicone and leave microcracks in which später smudge.

Alcohol wipes (rapid disinfection)

Ideal for daily cleaning of silicone straps, use wipes with 70% isopropyl alcohol (sold in pharmacies or electronics stores) not suitable for skin and fabric!

How to clean:

1. Wipe the strap with a napkin on both sides.
2. Pay attention to the fastener and mounting holes - there accumulates the most bacteria.
3. Let dry in the air for 5-10 minutes (alcohol evaporates quickly).

Alcohol dissolves skin fat more efficiently than soap, but does not remove deep contaminants (such as yellowness from sweat).

3. Baking soda (for persistent stains and odor)

Soda is a natural abrasive and deodorant, and it is suitable for silicone and fabric straps, but not for skin (can dry).

Instructions:

1. Mix the soda with water to a gruel state.
2. Apply on the strap with a soft brush, paying special attention to darkened areas.
3. Leave for 5-7 minutes, then rinse with warm water.

To enhance the effect, add 1-2 drops of tea tree essential oil to the mixture - it has antibacterial properties.

4. Vinegar solution (against mold and odor)

If the strap smells of mold or has not been cleaned for a long time, use 9% table cider vinegar diluted with water in a ratio of 1:1.

Algorithm:

• Immerse the strap in the solution for 15-20 minutes.
• Rub with a brush and rinse with water.
• Dry in the sun (UV light kills bacteria).

⚠️ Note: Do not use vinegar for straps with metal elements (for example, fasteners) - it can cause corrosion.

5. Toothpaste (for polishing silicone)

White toothpaste without pellets (like Colgate Total 12) helps to restore the shine of the faded silicone and remove the yellowness. Not suitable for fabric and skin!

How to apply:

1. Put the paste on the strap.
2. Rub with your finger or brush for 2-3 minutes.
3. Wash and dry.

💡

To enhance the effect, use a paste with a bleaching effect, but not more often than 1 time a month - frequent processing overdries silicone.

6. Special cleaners (for leather and premium straps)

For leather straps (Xiaomi Watch) S1) use:

• 🧴 Cleanser for the skin (for example, Collonil or Saphir).
• 🧼 Wet wipes for the skin (without alcohol!).
• 💧 Skin conditioning (after cleaning to avoid cracks).

Apply the product to a soft fabric, not directly on the strap. After cleaning, allow the skin to soak up the air conditioner for 10-15 minutes, then remove the excess with a dry wipe.

Ultrasonic bath (professional method)

If the strap is heavily contaminated (for example, after prolonged wear without cleaning), an ultrasound bath will help, which can be found in equipment repair shops or jewelry salons.

Advantages of the method:

• ✅ Removes dirt from micropores and cracks where the brush will not reach.
• ✅ Safe for silicone and metal (unless there is rust).
• ✅ It takes 5-10 minutes.

💡

For fabric straps, only hand washing in soap solution is suitable, machine washing or ultrasound will deform the fibers and lead to shrinkage.

What not to do when cleaning the Xiaomi strap

Even the most innocuous at first glance can ruin a strap. Here are the 5 most dangerous mistakes:

• 🔥 Boiling – silicone deforms, skin shrinks, tissue sheds.
• 🧼 Washing powder – contains abrasives that scratch the surface.
• 🍋 Lemon juice or hydrogen peroxide – bleached, but destroy the structure of the material.
• 🔌 Dryer or battery for drying - overdrying and leads to cracks.
• 🧴 Acetone or solvent – dissolves silicone and paint on fabric straps.

Be especially careful with straps with electronic components (for example, Mi Band 7 Pro with built-in sensor), getting moisture into the connectors can cause the bracelet to fail.

⚠️ Warning: If the strap becomes sticky after cleaning, you have used an overly aggressive agent (e.g., undiluted vinegar), in which case re-treatment with a solution of water and soda (1:1) to neutralize the acid will help.

How often to clean the fitness bracelet strap

The frequency of care depends on the intensity of wearing:

How to replace a strap if it deteriorates

If the strap is worn, cracked or lost its appearance, it can be replaced. Xiaomi has official accessories, but there are also universal options:

• 🔄 Original straps – sold in Mi Store or on AliExpress (look for the bracelet model).
• 🛒 Universal silicone – suitable for most Mi Bands (width 18–22 mm).
• 👔 Leather or metal – for premium appearance (for example, for Xiaomi Watch) S2).
• 🧵 Fabrics are breathable, but require frequent washing.

When choosing, pay attention to:

• 📏 The width of the mount (at the Mi Band) 6/7 — 18 Mmm, the Mi Band. 8 Pro — 22 mm).
• 🔗 Type of fastener (not all universal straps are compatible with original capsules).
• 💧 Waterproof (if you plan to swim with a bracelet).

💡

Cheap replicas of straps are often made from low-quality silicone, which cracks and smells quickly, and it's better to pay too much for the original or a certified accessory.
