How to remove scratches from the fitness bracelet Xiaomi Mi Band 6: from polishing to glass replacement

Xiaomi Mi Band 6 is one of the most popular fitness bracelets, but its plastic body and touch glass are vulnerable to mechanical damage. Even when used carefully, small scratches appear on the screen and body that spoil the appearance and can interfere with touch control. In this article, we will discuss 7 working ways to eliminate defects, from budget home methods to professional solutions.

It is important to understand that the depth of the scratch determines the choice of method. Surface microdamage (which feels like roughness to the nail) can be eliminated by polishing. Deep furrows (visible at an angle and clinging to the nail) will require more radical measures, up to replacing the glass, we will also tell you how to prevent new scratches and when to contact the service center.

Follow the instructions carefully!

1. Damage assessment: when scratches can be removed on their own

Before you start repairing, determine the type and depth of the scratches, take a clean nail and gently run it over the damaged surface:

• 🔍 Microdamage: the nail does not cling, the scratch is visible only under direct light.
• 📏 Medium scratches: the nail gets slightly stuck, the furrow is visible at an angle.
• ⚠️ Deep scratches: nail clearly clinging, possible sensor damage. Self-cleaning is risky - it's better to replace the glass.

Pay special attention to the sensor area (under the screen). If the scratches are located there and the bracelet does not respond well to touch, polishing can aggravate the problem, in which case it is optimal to turn off touch control in the Mi Fit settings and use a physical button.

Critical Zone: If the scratch is located above the pulse sensor (the green LED on the back), polishing can disrupt the accuracy of the measurements, in which case it is better to use a protective film or cover.

Budgetary methods: toothpaste, soda solution and wax

Surface scratches are suitable for the use of improvised tools, which have the advantage of being low cost and not risking damage to the bracelet (1-2 months), as these methods do not restore the structure of the material, but only mask defects.

Toothpaste (without abrasives!)

Use a bleaching paste without pellets (for example, Colgate Total 12 or Splat Whitening).Abrasive particles in whitening pastes can aggravate scratches.

Apply a drop of paste on soft tissue (microfibra)|rub in circular motions 2-3 minute|Remove the remains with a wet wipe|Dry with alcohol to degrease-->

⚠️ Warning: Do not use an electric toothbrush - vibration can damage the mounting of the screen to the body. Also avoid the paste entering the charging connector (marked by the symbol) 5V).

Baking soda + water

Mix the soda with water to the consistency of a thick paste. Apply on the scratch and polish with a cotton swab 1-2 This method is effective for matte plastic of the case, but it's not suitable for the screen - soda is too abrasive for glass.

Furniture wax or car polymer

Apply a thin layer of wax (such as Pledge or Turtle Wax)>) If you scratch, let it dry for 5 minutes and polish it with a dry cloth, the wax fills the microcracks and creates a protective layer, but it doesn't last long (wash with water).

💡

For the best effect, warm up the bracelet with a hair dryer before polishing (temperature not higher than 50).°C) This will open up the pores of plastic and improve the penetration of polyrell.

Professional means: pasta GOI, Displex and sandpaper

Silicone cases

Soft silicone cases (such as MoKo or Spigen) completely cover the body and screen, protecting against impacts. Minus - thicken the bracelet and can interfere with touch control.

⚠️ Attention: Cheap hard plastic covers often scratch the screen on their own due to internal burrs.

Liquid glass (nanocoating)

Compositions such as Nano Glass or Ceramic Shield create a protective layer thickness 3-5 They won't remove old scratches, but they will prevent new ones, they're applied like a regular film, but they last longer. 6 months).

💡

Before applying liquid glass, warm up the bracelet with an incandescent lamp (at a distance). 30 centimeter) 2-3 It'll improve the adhesion of the coating.

Radical measures: glass and case replacement

If the scratches are deep or the polishing techniques don't work, there are two options: changing the glass or completely replacing the case, both of which require disassembling the bracelet and risk impairing the leakage.

Replacement of glass

Glass for Mi Band 6 You can buy it on AliExpress (price — 200-500 or in service centers, you will need to replace:

• 🔧 Plastic mediator (for disassembly).
• 🔥 Hair dryer or thermo-air station (for softening glue).
• 🧴 Clay. B-7000 or LOCA (fixing).

Step-by-step:

Hair-dryer bracelet (60°C) 1-2 minute|Carefully subdue the glass with a mediator, starting from the corner|Clean the glue residues with alcohol|Apply new glue to the frame and press the glass|Scotch on 12 hours-->

⚠️ Warning: When disassembling, do not touch the screen plume - it is attached to the board with thin contacts. If the bracelet stopped turning on after replacement, check the integrity of the plume with a multimeter (resistance between contacts should be 0.5-1 Om).

Replacement of the hull

Complete replacement of the body (together with glass) will cost in 600-1200 It's more reliable than just replacing the glass, because the new case comes with factory sealing, and the downside is that you have to carry the board with the sensors, which requires a soldering iron and skill.
