Owners of Xiaomi, Redmi and POCO smartphones often face the need to remove the sticker from the device’s body, whether it’s a factory protective film that they forgot to remove when selling it, or an advertising sticker left after buying it in a store. Sometimes users glue decorative elements that eventually lose their appearance or interfere with the use of the case. The main difficulty is not in removing it, but in getting rid of the sticky layer that remains after dismantling.
Incorrect actions can damage the oleophobic screen covering or micro scratches on the glossy back panel. Especially carefully, if the sticker is near the sensors or on the glass surface. In this article, we will discuss proven methods that will help remove the sticker from the Xiaomi phone without harming the appearance of the gadget.
Many users mistakenly believe that removing the edge of the nail and pulling it sharply, but this approach often leaves a significant amount of glue that is difficult to remove with dry cloth. Moreover, a sharp mechanical impact can damage the paint coating on the metal or plastic elements of the body, so it is important to choose the right tool and chemical composition to dissolve the adhesive layer.
Preparation of the workplace and necessary tools
Before removing the sticker, you need to organize a clean and well-lit workspace, dust and dirt, caught under the solvent or on the sticky layer, will turn into an abrasive gruel, which is guaranteed to scratch the body, it is recommended to cover the table with a soft cloth or use a special antistatic mat, so that the accidentally fallen phone does not get damaged.
You'll need a set of simple tools that you can find in every home, a plastic card or a special mediator to open the housings, and metal objects like knives or blades are not recommended because they leave deep furrows on glass and metal, and you'll also need to prepare a soft, lilaless microfiber wipe that will not leave any villi on the surface.
- 🧴 Isopropyl alcohol or a special solvent for glue - the basis for softening the adhesive.
- 💳 Plastic card or spatula - for careful tweaking of the edges of the sticker.
- 🧻 Microfibre or napkins for optics - for final polishing and removal of residues.
- 💡 Bright light bulb for better visual control of cleaning process.
It's important to make sure all the chemicals you plan to use are safe for electronics.Isopropyl alcohol is the standard in the repair industry, as it evaporates quickly and does not conduct current.Regular ethyl alcohol or vodka can contain impurities that will leave stains or damage the plastic elements of the smartphone case.
Mechanical method of removal without heating
If the sticker is weak or paper-based, you can try to remove it mechanically without using aggressive chemistry. This method is suitable for fresh stickers that have not had time to stick to the surface due to the heat of the hands and time. Start by carefully examining the edges of the sticker to find the place where it most easily departs from the case.
Carefully tuck the sticker angle with your nail or plastic spatula. Try to keep the tool at a minimum angle to the surface, almost parallel to it, so as not to scratch the body. Slowly pull the sticker along the surface, not upwards, gradually increasing the angle of separation. If you feel strong resistance, do not force the process so as not to tear the paper.
⚠️ Warning: If the sticker breaks and stays on the case, don't rub it with your fingers.This will only drive the glue deeper into the surface texture and make it harder to clean further.
In cases where the sticker is made up of multiple layers, remove them sequentially. The top layer is often removed easily, leaving the bottom adhesive layer. It may require a slight thumb friction to remove it, rolling the glue into the coils. This method is effective for rubber bases, but requires patience and time.
💡
Mechanical removal is only effective for fresh stickers; older stickers require prior softening of the glue.
Using heat to soften glue
Heat exposure is one of the most effective ways to remove an old sticker from a Xiaomi phone.Heating allows you to soften the adhesive base, making it less viscous and more malleable. However, it is critical to maintain a temperature regime here so as not to damage the battery or internal components of the device, especially if the sticker is above them.
The best heating tool is a hair dryer set to a medium temperature. Don't use a building hair dryer as it can instantly melt plastic or damage the screen. Direct the flow of warm air to the sticker from 10-15 centimeters away. Keep the hair dryer in motion, evenly warming the entire area of the sticker for 30-60 seconds.
After warming up, try to re-inject the sticker edge. If it still resists, repeat the heating procedure. Heat also helps remove the glue residue: after removing the main part of the sticker, warm up the remaining sticky layer and quickly wipe it with a dry microfibre. The glue should easily collect on the fabric.
- 🌡️ Heat the surface gradually, avoiding local overheating at one point.
- ⏱️ The heating time is usually between 30 and 60 seconds.
- 🔥 Do not allow the heating of the body above 45-50 degrees Celsius.
- 📱 Remove the protective case before the procedure for better access.
There is a myth that you have to put your phone on a battery or hot surface, and you can't do that because you can't control the temperature, because overheating a lithium polymer battery can cause it to swell or even catch fire, and you can only use controlled heat sources like a hair dryer.
Chemicals for removing glue residues
When the bulk of the sticker is removed, it often leaves a sticky layer on the body that attracts dust and looks unaesthetic. Isopropyl alcohol is ideal for removing it. It effectively dissolves most types of glue without leaving traces and evaporates quickly. Apply a small amount of alcohol on the napkin, rather than directly on the phone, so that the liquid does not leak into the connectors.
If isopropyl alcohol is not available, you can use screen cleaners or citrus oil-based stickers to remove them, but you need to be careful about the latter: they may contain aggressive components that can damage plastic or paint. Always test any product on an inconspicuous area of the case before full use.
For persistent contaminants, vegetable oil can be used, but only with extreme caution. The oil dissolves glue perfectly, but it is very difficult to completely flush off the phone, and it can clog into the speaker or microphone. If you choose this method, after removing the glue, carefully degrease the surface with alcohol.
Specifics of cleaning different materials of the body
Xiaomi smartphones come in a variety of materials, and each requires a personalized approach. Glossy plastic and glass are more sensitive to scratches but are easier to clean from glue. Matte surfaces and metal may require more intense friction, but the risk of leaving visible scuffs on them is lower.
Special attention should be paid to the screen. If the sticker was on the display, use only the softest fabrics and minimal alcohol. The oleophobic coating of the screen is very tender, and aggressive friction or the use of acetone can completely destroy it, making the screen dull and quickly dirty.
| Case material | Recommended remedy | Risks. | Tool. |
|---|---|---|---|
| Glass (screen/back) | Isopropyl alcohol | Particulate scratches | Microfiber |
| Glossy plastic | Screen special fluid | Surface clouding | Cotton disc |
| Metal (aluminum) | Alcohol or butter | Oxidation (rarely) | Flour without pile |
| Eco-skin | Dry cleaning, minimum moisture | Texture damage, color damage. | Soft brush |
If your smartphone has an eco-skin back, like some of Xiaomi's flagship models, it's best to refrain from using liquids. The glue from such surfaces is removed mechanically, by gently rolling your finger. The chemistry can change the color or texture of artificial leather, making the defect more noticeable than the sticker itself.
What not to do: Common mistakes
In pursuit of quick results, users often make mistakes that cause permanent damage to the device, the most common being the use of acetone, paint solvents or varnish removal fluid, which aggressively impact plastic, instantly making it cloudy and sticky, and can also corrode paint on a metal case.
Another mistake is using blades, scissors or metal scrapers. Even if you think you're being neat, metal is harder than most smartphone coatings. One awkward move will leave a deep scratch that you can't polish at home. Use only plastic or wood to tweak the edges.
⚠️ Warning: Never pour liquid directly onto your phone! The liquid can leak under the screen, into the charging connector or speaker, causing the device to short-circuit and fail.
Also, you should not use abrasive sponges for washing dishes (the side with a hard pile), they are designed for pans, not for delicate electronics. These sponges leave a net of micro scratches, which when the screen is turned on will create a rainbow effect or glare, worsening visual perception.

Final processing and protection of the device
After successful removal of the sticker and glue, you need to perform a final surface cleaning. Wash the case with a dry microfiber to remove possible stains from alcohol or cleaner. Make sure that the speakers and connectors do not have any villi from the wipes that could stick to the glue residue.
If you notice that the oleophobic coating of the screen is damaged or worn during the cleaning process, consider installing a protective glass that will not only hide minor defects, but also protect the screen from further damage.
Check the status of the sticker regularly if you choose to leave any of them (for example, the warranty on the back, although Xiaomi service centers most often do not require it). Over time, the glue can leak and stain the case, so it is better to remove all third-party items immediately after purchase.
