How to remove scratches from the fitness bracelet Xiaomi Mi Band 5: from polishing to radical methods

Xiaomi Mi Band 5 is one of the most popular fitness bracelets on the market, but even its durable plastic body is not immune to mechanical damage. Scratches spoil the appearance, and deep defects can eventually lead to cracks or leakage. In this article, we will discuss 7 effective ways to remove scratches, from budget home methods to professional solutions that will return your gadget to its original appearance.

It is important to understand that not all scratches are the same: superficial (small, not clinging to the nail) are eliminated by polishing, and deep (tangible to the touch) may require more radical measures. We will also tell you which methods are categorically contraindicated for the Mi Band 5 - their use can irrevocably spoil the device.

Before you start repairing, assess the damage: hold the bracelet to the light source at an angle. Small scratches will reflect light differently, and deep scratches will form a shadow, which will help you choose the best way to restore.

Preparation of the bracelet for repair: what to do before the start of work

Incorrect preparation can nullify all efforts to remove scratches. Follow this checklist to avoid mistakes:

Turn off the bracelet (press the touch button for 5 seconds)

Remove the strap (greatly pull the locks on the back side)

Clean the case of dirt and fat (use isopropyl alcohol 70% and a lilac-free napkin)

Stick the touch button and connectors with paint tape

Check the leakproofness after repair (do not turn on if there are traces of moisture left)-->

Pay special attention to cleaning: greasy marks from skin or creams can interfere with even polishing. To remove persistent contaminants, use a cotton swab soaked in alcohol, but do not rub too hard - the Mi Band 5 plastic is softer than it seems.

If the scratches are located with a touch button or a charging connector, tape these areas with paint tape in 2-3 layers, which will prevent abrasive particles or polishing from entering the device. Remember, damage to the internal contacts can lead to complete inoperability of the bracelet.

⚠️ Warning: Never use acetone, solvents or abrasive sponges to clean the plastic, which breaks down the protective coating and makes it more vulnerable to new scratches.

2. Method 1: Polishing toothpaste – myth or reality?

This is a technique that is often mentioned online, but it only works for small surface scratches. Toothpaste contains microscopic abrasive particles that smooth out irregularities but do not cope with deep damage. For the Mi Band 5, only white paste without gel additives (for example, Colgate Classic or Splat Whitening) is suitable.

Instructions:

• 🧴 Apply a paste pea to a soft microfiber fabric (not on the bracelet itself!).
• 🌀 Circular movements with light pressure polish the scratch 2-3 minute.
• 💧 Remove the leftovers of the paste with a wet wipe and dry the bracelet 10-15 minute.
• 🔍 Check the result under bright light – repeat the procedure if necessary.

The effect of this method is temporary: after 1-2 weeks, scratches may become noticeable again, since the paste does not restore the structure of the plastic, but only masks defects.

3. Method 2: Professional polymers for plastic

For deep scratches, it is better to use specialized products. Unlike toothpaste, they contain polymer fillers that fill microcracks and restore gloss.

Application technology:

1. Apply a small amount of polish on a cotton disc or soft tissue.
2. Rub the scratch with straight-line movements (not in a circle!) for 3-5 minutes.
3. Remove the excess with a dry wipe and polish the surface until it shines.

For matte Mi Band 5 after polishing, it is recommended to apply colorless wax for plastic (for example, Turtle Wax) - this will return the factory texture and protect against new scratches for 1-2 months.

💡

Before buying polyrole, check its compatibility with polycarbonate - this is the material made of the body of the Mi Band 5. Information is usually indicated on the package in the section "Suitable materials".

4. Method 3: Heat treatment (only for power users!)

This is a good way to deal with deep scratches that are not removed by polishing, and when heated, the plastic softens and the top layer of the plastic leaks out, masking defects, but it requires extreme care: overheating can deform the body or damage the internal components.

Step-by-step:

• 🔥 Heat the building dryer to temperature 150-180°C (not higher!).
• 🌀 Keep the hair dryer at a distance. 10-15 cm from the bracelet, constantly moving it to avoid local overheating.
• ⏱️ Heat the scratch no more. 10-15 Seconds – the plastic should be slightly soft, but not melt.
• 🧊 Immediately cool the bracelet by attaching a metal object (such as a spoon) to it. 20-30 seconds.

⚠️ Attention: This method is not suitable for bracelets with damaged display or bloated battery. Heating can aggravate the problems. Also, do not use a lighter or open fire - this will lead to melting of the body.

After heat treatment, the surface may become less glossy. To return the shine, polish the bracelet with wax for car headlights (for example, Sonax Plastik Glanz).

5. Method 4: Masking scratches with coatings

If the scratches are too deep to polish, but you don't want to risk heat treatment, you can camouflage them with special coatings. This method doesn't eliminate the defects, but makes them less noticeable.

Coating options:

• 🎨 Car lacquer in a can (for example, Motip Clear Lacquer): applied in 2-3 thin-layer 10 It's perfect for glossy bracelets.
• 🖌️ Nail gel (transparent): fills in the scratches and creates a protective layer. It is applied with a brush, dried under the skin. UV-lamp 2-3 minute.
• 🛡️ Hydrophobic coating (e.g. Nano Protect): forms an invisible film that hides minor defects and protects against new scratches.

Before applying the coating, be sure to degrease the surface of the bracelet with isopropyl alcohol. Use an airbrush or a soft pile brush to evenly distribute the varnish. After drying (24 hours), the coating can be further polished with GOI paste.

Life of coatings:

• Car lacquer: 3-6 months (may turn yellow over time).
• Nail gel: 1-2 months (prone to chipping when hit).
• Hydrophobic coating: up to 1 year (requires re-application after washing the bracelet).

Method 5: Replacing the body is a radical but reliable solution

If the scratches are too deep or too many, the most reliable way is to replace the case. Original parts for Xiaomi Mi Band 5 cost from 300 to 800 rubles depending on color and material, you can buy them on AliExpress, Beru or Xiaomi service centers.

How to change the body yourself:

1. 🛠️ Carefully tuck the plastic cover on the back of the bracelet (use a mediator or plastic shoulder blade).
2. ⚙️ Disconnect the display plume and battery (take photos of the process so as not to confuse the assembly order!).
3. 🔄 Move all components to a new enclosure, respecting the polarity of the contacts.
4. 🔧 Secure the lid, making sure it fits tightly (check the tightness with a waterproof test).

If you are not sure about your skills, you should contact a service center. The cost of replacing the body in the workshop will be 500-1200 rubles, but you will get a guarantee for work. If you replace it yourself, the risk of damage to the plume of the display or battery is about 20%.

💡

When buying a new case, pay attention to its serial number - it must match the original one (starting with the MDZ-09-D for the Mi Band 5).

7. Scratch prevention: how to protect the bracelet in the future

The best way to fight scratches is to prevent scratches. Here are 5 proven methods of protecting Xiaomi Mi Band 5:

• 🛡️ Protective film: transparent vinyl stickers (like Spigen Tempered Glass) are 200-300 and reduce the risk of scratching on 70%.
• 🧤 Silicone case: Full bumpers (such as Ringke Fusion) protect against impacts, but can interfere with the sensor.
• 💍 Wearing on the other hand: If you work with your hands often, transfer the bracelet to a less active hand.
• 🧼 Cleaning regularly: Sand and dust act like an abrasive – clean the bracelet once in a while 3-4 day-day.
• 🚫 Avoid contact with keys/coins: Keep the bracelet separately in a case or box.

For additional protection, you can apply a ceramic coating (for example, Ceramic Pro), which forms a hard layer with a thickness of 2-5 microns. The cost of applying in the service is from 1500 rubles., But the coating will last 2-3 years.

If you are exercising, remove the bracelet during resistance exercises (barrels, dumbbells) - metal easily scratches plastic. Also avoid wearing the Mi Band 5 in a sauna or bath: high temperatures make plastic more fragile.
