How to Clean a Xiaomi Watch from Silicone Stripe: From Daily Care to Deep Cleaning

Xiaomi’s smartwatch silicone straps are a practical solution: they’re lightweight, water-resistant and durable. But even the best silicone eventually loses its original appearance: dark bands of sweat, unpleasant smells, and dirt accumulates in the texture of the material. This is a particularly important issue for Mi Band owners. 5/6/7 Xiaomi Watch S1/S2, wearer.

In this article, we've got 7 proven cleaning methods, from quick daily care to deep cleaning of old contaminants, which are safe for silicone and which can spoil it, and recommendations for prevention, all of which are tested on Xiaomi straps and require no special skills.

Why Silicone Straps Get Stained and What It Means

Silicone is a porous material that actively absorbs moisture and fat, the main causes of pollution are:

• 💦 Sweat and skin fat - when wearing watches on the hand, up to 1-2 ml of sweat per hour is released, which mixes with dust and forms a sticky plaque.
• 🧴 Cosmetics and creams – particles of hand creams, lotions or perfume settle in the micropores of silicone.
• 🌡️ Temperature changes – when heated (for example, in the sun), silicone expands, “drawing” dirt deeper.
• 🦠 Bacteria and fungus – a moist environment is ideal for the reproduction of microorganisms that cause the smell.

If you do not clean the strap regularly, the consequences will be noticeable after 2-3 months:

• 🟤 The appearance of yellow or gray spots (especially on white straps).
• 🤢 A persistent smell that does not clear even after washing with water.
• 🧩 Material stratification – dirt acts as an abrasive, destroying the structure of silicone.
• 🚫 Skin irritation – a buildup of bacteria can cause itching or rash.

⚠️ Warning: Do not use acetone, gasoline or solvents to clean, they break down silicone, making it brittle. Also avoid hard brushes (such as metal ones) that leave micro-scratches.

Preparation of the strap for cleaning: what to do before the procedure

Before cleaning, be sure to unplug the strap from the watch case. on most Xiaomi models (such as the Mi Band 7 or Xiaomi Watch). S1 Pro, you need it:

1. Turn the clock back to your side.
2. Find a small button or latch on the back of the strap.
3. Press it with a screwdriver or nail and pull the strap to the side.

If the latch doesn't lend itself, don't put too much effort into using a plastic shoulder blade (combined with some smartphones) or a credit card. On Xiaomi Watch 2 Pro and later, you use a magnetic fastener, so you just pull the strap up with effort. ~5 N.

Disconnect the strap from the clock|

Prepare all the products in advance (soap, brush, wipes)|

Check the strap for cracks or damage|

Remove rings/bracelets from your hand to avoid scratching silicone-->

Also check the integrity of the strap:

• 🔍 If there are cracks or tears, cleaning with water can aggravate the damage.
• 🎨 Colored straps (e.g. blue or green) can water when using aggressive means – test them on a small area.

Method 1: Quick cleaning with water and soap (for daily care)

This method is suitable for mild contaminants and is recommended to use 1-2 times a week.

• 🧼 Liquid soap (preferably antibacterial) or dishwashing agent.
• 🧽 Soft toothbrush or microfiber napkin.
• 💧 Warm water (not hot! optimally 30-40)°C).

Step-by-step:

1. Moisten the strap in warm water for 1-2 minutes to soften the dirt.
2. Apply a few drops of soap to the brush and gently clean the strap on both sides, paying attention to:

Wash the strap under running water, removing the residue of soap.

💡

To enhance the effect, add 1 tbsp. spoonful of baking soda to the water - it neutralizes odors and helps whiten the yellowed areas.

This method removes up to 80% of surface contaminants, but is powerless against old spots or fungus. For deep cleaning, move on to the following methods.

Method 2: Ultrasonic bath (for persistent contaminants)

If the strap is heavily contaminated (for example, after prolonged wear without cleaning), an ultrasonic bath will help remove dirt from the deepest pores. 4/5/6 and other models with dense silicone.

What do you need?

• 🛁 Ultrasonic bath (you can buy an inexpensive model for jewelry).
• 🧴 Special solution (or a mixture of water and soap in a ratio of 10:1).
• ⏱️ Timer – Do not exceed processing time!

Instructions:

1. Pour the solution into the bath (temperature not higher than 40)°C).
2. Place the strap in the bath and turn it on for 3-5 minutes.
3. After processing, wash the strap with water and dry.

⚠️ Note: Do not use ultrasound for straps with metal inserts (e.g. Xiaomi Watch) S1 Active - vibration can damage the attachments.

Method 3: Cleaning with vinegar or citric acid (against smell and bacteria)

If the strap starts to smell and it gets dark spots, it's bacteria or fungus that's to blame, and then acid treatment, which kills up to 99 percent of the microorganisms, will help.

Option 1: Table vinegar (9%)

1. Mix vinegar with water in a 1:1 ratio.
2. Immerse the strap in the solution for 15-20 minutes.
3. After soaking, clean with a brush and rinse with water.

Option 2: Citric acid

1. Dissolve 1 tsp. of citric acid in 200 ml of warm water.
2. Soak the strap for 10 minutes.
3. Rinse and dry.

These methods not only eliminate the smell, but also lighten the yellowed areas, but after acid treatment, the silicone can become a little stiffer — a temporary effect that goes away in 1-2 days.

Method 4: Baking soda paste (for whitening and deep cleaning)

Baking soda is a soft-acting abrasive that does a great job with:

• 🟡 Yellow on white or light straps.
• 🖤 Black stripes of sweat.
• 🦠 Older Pollutions in the Texture of Silicone.

How to make pasta:

1. Mix soda with water to the consistency of thick sour cream.
2. Apply the paste on the strap with a toothbrush.
3. Leave for 5-10 minutes (no longer, otherwise the soda can overdry the silicone!).
4. Wash it with warm water.

To enhance the effect, add hydrogen peroxide (3%) to the paste, which will increase the bleaching effect. But remember, peroxide can slightly change the color of bright straps (red, blue).

💡

Soda is the only abrasive that's safe for silicone, and all other powders (such as kitchen cleaners) scratch the surface and accelerate wear.

Method 5: Alcohol or antiseptic (express disinfection)

If you need to disinfect the strap quickly (for example, after sports), use:

• 🧴 Isopropyl alcohol (70%) – kills 99.9% of bacteria.
• 💊 Chlorhexidine: Safe for silicone and skin.
• 🧻 Wet wipes with antiseptic (for example, for treating hands).

How to apply:

1. Apply the product to a cotton disc or a napkin.
2. Wipe the strap on both sides, paying attention to the joints.
3. Let it dry in air (alcohol evaporates in 1-2 minutes).

This method doesn't remove dirt, it only disinfects. For a comprehensive cleaning, combine it with washing with water.

⚠️ Warning: Do not use medical alcohol (96%) - it is too aggressive for silicone and can cause cracking.Dilluminate it with water to 70% concentration.

Method 6: Steam treatment (for delicate cleaning)

If you're afraid of damaging your strap with water or chemicals, try steam cleaning.

• 🎨 Colored straps that can be moistened.
• 🆕 New models (e.g. Xiaomi Watch) S3) delicately coated.
• 🧼 Allergic drugs that are contraindicated by chemicals.

What do you need?

• 💨 Steam generator (or iron with steaming function).
• 🧻 Soft fabric for condensation collection.

How to clean:

1. Hold the strap over the steam at a distance of 5-10 cm for 2-3 minutes.
2. The dirt will soften - remove it with a napkin.
3. Repeat the procedure for the other side.

The vapor kills bacteria and removes up to 70% of the contaminants without mechanical action, and the method will not cope with old spots.

Method 7: Special products for silicone (professional care)

If home methods do not help, use professional chemistry:

These funds are more expensive than home counterparts, but:

• ✅ Do not damage silicone.
• ✅ Longer retain the effect (up to 1-2 months).
• ✅ Often contained UV-filters that prevent burnout.

Where to buy: in car stores (care departments) or on AliExpress (search for "silicone cleaner").

How to Prevent Fast Contamination of a Belt: 5 Rules

To keep the slack clean for longer:

1. 🚿 Take off the watch in front of a shower or pool – chlorine and salt accelerate the wear of silicone.
2. 🧴 Apply the cream 10-15 minutes before putting on the watch so it will soak up.
3. 🔄 Alternate straps – if you wear the watch around the clock, buy 2-3 replacement straps.
4. 🧼 Wash the strap with a wet wipe after training or active sweating.
5. ☀️ Keep your watch in the shade – direct sunlight destroys silicone.

The average lifespan of a silicone strap, if properly maintained, is 1.5 to 2 years, and then it loses its elasticity and begins to crumble.
