Scratches on the Xiaomi Mi Band 6 screen are a problem that almost every wearer of this fitness bracelet faces. Despite the manufacturerβs stated strength of the display (hardened glass with oleophobic coating), microdamages appear from contact with keys, coins or even sand in his pocket. Unlike smartphones, there is no way to paste a glass protective screen β you either have to put up with defects or find ways to fix them.
In this article, we will discuss 7 working methods, from gentle polishing to radical glass replacement, taking into account the specifics of the Mi Band 6. Importantly, not all scratches can be removed completely, but most of them can be made less noticeable. We will also explain why standard βfolkβ methods (for example, toothpaste) often make things worse. AMOLED-screens, and we will give a checklist for safe processing.
Before you start, assess the depth of the damage: swipe your nail over the scratch. If it gets caught, it's a deep scratch (not only the oleophobic layer is damaged, but the glass itself is damaged), and you can't do without polishing or replacing it. If the scratch is only visible from a certain angle, the chances of successful removal are higher.
1. Screen Preparation: What to Do Before Processing
Incorrect preparation can turn a small scratch into a network of microcracks. Follow this algorithm to avoid additional damage:
- π§Ό Screen cleaning. Use isopropyl alcohol (70% or higher) or special wipes for optics. No water or household chemicals, they leave a divorce that will prevent you from assessing the result.
- π Lighting. Light up the screen with a 45-angle flashlight.Β° β So you can see the scratches as clearly as possible. Take a picture of the damage before the treatment for comparison.
- π‘οΈ Protect the case, seal the plastic parts of the bracelet with paint tape so that they do not damage the polishing compounds.
Note that if there are chips on the screen (there are no glass fragments), polishing is contraindicated - it will expand the damage. In this case, immediately go to the section about replacing the glass.
β οΈ Warning: Do not use paper wipes or toilet paper for cleaning - their fibers leave new mycroscraps.
2. Method 1: Recovery of oleophobic coating (for small scratches)
If the scratches are barely noticeable and do not "cling" the nail, most likely, only the upper oleophobic layer is damaged, and it can be repaired using special compounds:
- Apply 1-2 drops of oleophobic coating repair products (such as Displex or NanoMagic Screen Protector) to a microfiber wipe.
- With light pressing, circle the screen for 30 to 60 seconds.
- Remove the excess with a dry wipe and allow the coating to polymerize for 12 to 24 hours (do not wear the bracelet at this time).
This technique doesn't physically remove scratches, but it makes them less visible by filling up the micropores and restoring the sliding effect, and is suitable for surface damage that is not visible when the screen is off.

If there is no specialized formulation, temporarily replace it with a drop of vegetable oil (for example, flaxseed). The effect will last 2-3 days, but this is enough to assess whether to buy a professional remedy.
3. Method 2: Polishing with GOI paste or diamond paste
Mechanical polishing is suitable for scratches of medium depth (visible when the screen is turned off, but not βgrabbingβ the nail), and this method requires carefulness, since if you press too hard, you can wean the oleophobic coating or even damage it. AMOLED-matrix.
| Materials | Graininess | Application | Risks. |
|---|---|---|---|
| pasta GOI β1 | fine-grained | Final polishing | Can leave divorces if applied incorrectly |
| pasta GOI β2 | Medium | Removal of noticeable scratches | Requires a mandatory final polishing paste β1 |
| Diamond paste (1 ΞΌm) | Very small. | For delicate screens | Expensive, hard to find at retail |
Instructions for polishing:
- Apply a drop of pasta to a felt circle (or soft cloth without pile).
- Polish the screen in circular motions with a minimum pressure of 2-3 minutes.
- Remove the remaining paste with alcohol and examine the screen. Repeat the procedure if necessary.
β οΈ Warning: Do not use electric polishing machines β even at minimal revs, they overheat. AMOLED-Mi Band 6 screen, which can lead to broken pixels.
Method 3: Ultrasonic bathing (for mycroscrapines)
Ultrasonic cleaning helps remove microparticles of dirt from scratches, making them less noticeable, a technique only suitable for shallow damage and requires special equipment (an ultrasonic cleaner for jewelry).
Algorithm of action:
- Pour distilled water or isopropyl alcohol into the bath.
- Place the bracelet in the cleaner basket (do not allow contact with the fluid of the connectors!).
- Set the time of 2-3 minutes at a temperature of 30-40 Β° C.
- After processing, dry the bracelet 24 hours before use.
The effect is achieved by vibrations that knock out the dirt from the microcracks, but the method does not remove the scratches themselves, it only improves the appearance of the screen.

5. Method 4: Replacement of protective glass (radical method)
If the scratches are deep or too many, the only reliable way is to replace the glass. Unlike smartphones, the Mi Band 6 has a screen glued to the body, so the procedure requires care.
- π§ A set of plastic mediators (for disassembly).
- π₯ Hair dryer or thermoplatform (to soften glue).
- 𧴠Clay. B-7000 or similar (to fix a new glass).
- π± New glass for Mi Band 6 (sold on AliExpress or service centers).
Step-by-step:
βοΈ Preparation for glass replacement
- Carefully tuck the glass on either side and slowly separate it from the body, moving around the perimeter.
- Clean the remains of the glue from the body with alcohol.
- Apply a thin layer of B-7000 glue to the new glass and press it against the body.
- Secure the glass with tape and leave it under a press (such as a stack of books) for 12 hours.
The cost of new glass - from 300 to 800 rubles. If you are not sure of their skills, it is better to contact the service: the price of replacement in the workshops starts from 1,200 rubles.
Method 5: Folk remedies - what works and what does not
The Internet often advises using toothpaste, soda solution, or wax to polish screens, and for the Mi Band 6, most of these methods are not only useless, but dangerous.
| Remedy. | The effect | Risks for the Mi Band 6 |
|---|---|---|
| Toothpaste | Can smooth out mycroscraps | Abrasive particles scratch AMOLED-matrix, remove the oleophobic coating |
| Baking soda | Minor polishing | Alkaline eats glue at the edges of the screen, violates tightness |
| Wax for furniture | Temporary filling of scratches | Leaves a sticky plaque that attracts dust |
| jelly | Masking scratches for 1-2 days | Gets into the connectors, disrupts the sensor |
The only relatively safe "folk" remedy is a solution of vinegar and water (1:1). It helps dissolve mineral deposits in scratches, but does not physically remove them. Apply the solution for 10 seconds, then rinse with alcohol.
π‘
No folk remedy will restore the original strength of the screen, and at most, it will temporarily improve the appearance, but often at the cost of new damage.
7.How to prevent scratches in the future
Even after the scratches have been successfully removed, the risk of them reappearing remains. To protect the Mi Band 6 screen, follow these tips:
- π‘οΈ A liquid glass film, applied as a protective coating, increases the hardness of the screen by 1-2 Mohs units. It lasts 3-6 months.
- π Proper storage: Wear the bracelet inside your wrist to minimize contact with foreign objects.
- πΏ Avoid sand and dust. After the beach or repair, clean the bracelet with compressed air (with a canister for equipment).
- π Contacting the metal charger connectors can leave micro-damage.
If you are active in sports or work in dusty environments, consider buying a silicone case with a transparent screen insert, which will add 0.5 mm to the thickness of the bracelet, but will reliably protect against mechanical damage.
