When buying high-quality protection for the Xiaomi Redmi smartphone screen, many users are surprised to find not only the tempered glass itself, but also a small bag of liquid. Often this element is ignored or thrown away by mistake, which is a serious mistake, because this component plays a key role in the final result.
Without careful surface preparation, even the most expensive glass will not fit perfectly, causing rainbow stains or flaking at the edges in a couple of days, and in this article, we will take a closer look at the chemical composition of this liquid, explain the physics of the adhesion process, and provide step-by-step instructions on how to turn a conventional sticker into professional protection.
It's important to understand that today's smartphone screens are covered with an oleophobic layer that repels fat but eventually becomes contaminated, and that the alcohol solution in the bag is designed to effectively dissolve these contaminants without damaging the display and the oleophobic layer itself, and ignoring this stage of preparation is the main reason for self-installation.
Chemical composition and principle of action of degrimer
The liquid in the small soldered sachets is not just water, but a special solution based on isopropyl alcohol or its high-purification analogues. The main task of this compound is to instantly dissolve organic compounds, skin fat and cosmetic residues that inevitably accumulate on the surface of the Xiaomi display. Normal water with fat can not cope, and the use of aggressive household chemicals can damage the matrix.
The principle of operation is based on high volatility and the dissolving ability of alcohol. When contacted with the surface of the screen, the liquid instantly destroys the fat bonds, then quickly evaporates, leaving no divorces, which is why the kit also comes with a lilaless wipe made of microfiber: it is necessary for mechanical removal of dissolved fat before the alcohol evaporates.
- 🧪 Solvent: The basis is isopropyl alcohol, which is safe for electronics in short-term contact.
- 💧 Distilled water: Added to reduce the aggressiveness of pure alcohol and control the rate of evaporation.
- ✨ Polymer additives: Some premium sets may contain micro-additives that improve glass slip when positioned.
Can I use regular vodka or cologne?
It is worth noting that the alcohol concentration in the factory sachets is experimentally selected to achieve a balance between the rate of drying and the efficiency of cleaning. Using too strong alcohol can overdry the rubber seals of the speaker if the liquid flows in and too weak solution simply spreads the fat on the screen.
Why you should not miss the degreasing stage
Many users think it's easy to wipe the screen with a dry cloth, but the human eye can't see the thinnest fat film. This film creates a micro gap between the protective glass and the smartphone matrix. In places where there is fat left, the adhesion will be completely absent, which visually manifests as unpatched areas or "bubbles".
In addition, fatty contamination can oxidize or change over time under the heat of the processor, which will cause a color change at the site of contamination. On a white background, such spots will look like yellow or gray blots that cannot be removed without gluing the glass. Xiaomi Redmi have a dense layout and clearances are minimal, so the purity of the surface is critical.
⚠️ Warning: Never try to stick glass onto a "just wiped" screen.Even if you think your fingers were clean, a microfilm of fat remains on the display surface 100% of the time after any touch.
Another cause is static electricity. Dry wiping often only increases the electrostatic charge, attracting new dust from the air. Wet treatment with alcohol solution helps neutralize the static, creating more favorable conditions for stickers. If you skip this step, the risk of dust particles falling under the glass during installation increases many times.
Instructions: How to properly prepare the Redmi screen
The screen preparation process is the foundation of the whole operation, and how well you spend those minutes depends on the life of the protection, first you turn off your smartphone to better see the contamination and avoid accidental pressing, then you take a bag of cleaning fluid and carefully cut the corner.
Don't pour liquid directly onto the screen! Squeeze a few drops onto the corner of a microfiber napkin (usually marked with a 1 or an A.) With circular motions, wipe the entire surface of the display carefully, paying special attention to the edges and areas of the speaker where the most fat accumulates. After that, wipe the screen dry with the same dry side or corner of the napkin.
