What You'll Learn

Clean your screen and work area
To successfully install a plastic screen protector, you must ensure that your screen and work area are clean. Dust is the most important thing to remove before applying a screen protector, as it can get trapped underneath and is difficult to remove. To minimise dust, find a low-dust workspace, ideally a calm indoor area with no wind. Running a hot shower can also help, as the steam will cause the dust to settle.
Before you begin, wash your hands and dry them with a clean towel. Vigorously cleanse your screen with a microfibre cloth to remove fingerprints and smudges. You can apply a small amount of moisture to aid this process by breathing on the screen as you would when cleaning eyeglasses. Avoid using tissues or paper towels, or any cleaning solution other than a diluted alcohol-based solution, as these can damage the screen.
Once your screen is clean, check your screen protector for dust. Use a mild adhesive, such as a sticky note, to remove any residual dust from the screen protector. Look at the reflection of a bright area on the screen at an angle to confirm the presence or absence of dust.
Finally, ensure your work area is clean and free of dust. Any dust that falls onto your screen during the application process will be trapped underneath the screen protector.

Wash your hands
Before installing a plastic screen protector, it is important to wash your hands to ensure you don't leave any fingerprints or smudges on the adhesive side of the screen protector. Here is a detailed, step-by-step guide on how to wash your hands effectively for this purpose:
Prepare the Workspace
Firstly, ensure your workspace is clean and well-lit. The installation process requires precision, and good lighting will help you see any dust or dirt more clearly. Prepare your workspace by laying out all the tools and materials you will need, including a sink or basin for washing your hands.
Wet Your Hands
Start by wetting your hands with clean, running water. The temperature of the water doesn't matter, but warm or lukewarm water may be more comfortable. Avoid extremely hot water as it can be harsh on your skin and cause dryness.
Apply Soap
Dispense a small amount of mild soap or hand wash onto your palms. Avoid using harsh or heavily scented soaps, as these may irritate your skin or leave a strong residue. Liquid soap is generally more hygienic than bar soap, as it doesn't retain as much moisture and bacteria.
Lather and Scrub
Rub your hands together vigorously to create a rich lather. Be sure to scrub all areas of your hands, including the backs of your hands, between your fingers, and under your fingernails. This process should last for at least 20 seconds. A good way to time this is to hum the "Happy Birthday" song twice, or think of another short song or rhyme that lasts around 20 seconds.
Rinse and Dry
Rinse your hands thoroughly under running water to remove all traces of soap. Dry your hands completely with a clean towel or air dryer. If using a towel, ensure it is replaced regularly to maintain hygiene.
Now that your hands are clean, you can proceed with the installation of your plastic screen protector, ensuring no fingerprints or smudges are transferred to the adhesive side of the protector. Remember to work in a dust-free environment to avoid any particles getting trapped under the screen protector during installation.

Use guide stickers or tape
Using guide stickers or tape is a great way to ensure your plastic screen protector is applied accurately. Many screen protectors come with guide stickers, but you can also use tape if yours does not.
First, ensure your screen is clean and free of dust. You can use a dust sticker or a piece of tape to lift off any remaining dust particles. You can also use a mild adhesive, such as a sticky note, to remove dust.
Now, place the screen protector as if to install it, without removing the backing. If using guide stickers, place them on one edge of the screen protector to create a hinge. If using tape, take two pieces of low-tack tape, such as Scotch tape, about an inch long. Place the tape on the non-sticky side of the screen protector, with half on the protector and the other half sticking off the edge.
With the protective film still on, place the screen protector on your device and line it up. The tape or guide stickers will allow you to adjust the position without touching the screen with your fingers. Once you are happy with the placement, gently press the screen protector onto your screen.
Finally, remove the guide stickers or tape, taking care not to lift the screen protector. Use a plastic squeegee or a credit card to remove any air bubbles.

Remove dust with adhesive
Dust is the most crucial element to eliminate when applying a screen protector, as bubbles will eventually disappear, and fingerprints will likely blend with the glue. However, dust particles will remain. Before installing a plastic screen protector, it is essential to remove any dust particles from the adhesive side. Here are some detailed instructions to effectively remove dust with adhesive during the installation process:
Firstly, find a place with minimal airflow to reduce dust in the air. Close any windows or doors nearby and wait a few minutes for the dust to settle. This simple step will help minimise the amount of dust in the environment, reducing the chances of dust landing on your screen protector during the installation process.
Secondly, prepare your dust removal tools. Some screen protectors come with dust removal stickers or strips designed specifically for this purpose. If your screen protector kit includes a dust removal sticker, have it readily available. Alternatively, you can use a sticky note, a piece of cellophane tape, or a similar adhesive product. It is important to have these tools ready beforehand, as you will be holding the screen protector in one hand during the dust removal process, making it challenging to access the tools.
Now, it's time to inspect your screen protector. If you notice dust particles on the adhesive side of the screen protector, it is essential to act carefully. Avoid touching the adhesive with your fingers, as this can create unevenness in the adhesive and affect the screen protector's adhesion. Instead, gently lift the screen protector from the device, ensuring that the sticky side faces downwards to prevent further dust accumulation.
With the screen protector lifted, use your chosen adhesive tool to remove the dust particles. If you are using a dust removal sticker or sticky note, gently dab it over the adhesive side of the screen protector to pick up any dust. If you are using tape, carefully place it on the adhesive side, pressing down gently to ensure the dust particles adhere to the tape. Once you have removed the visible dust, quickly proceed to the next step to avoid attracting new dust particles.
Finally, carefully reapply the screen protector to your device, being mindful not to touch the adhesive side. Slowly press down on the screen protector, paying extra attention to the areas where dust was previously present. This will help ensure a smooth, bubble-free finish. If you notice any remaining bubbles, use a soft cloth to gently push them towards the edges of the screen. Apply light and even pressure to avoid damaging the protector.
By following these detailed steps, you can effectively remove dust with adhesive during the installation of your plastic screen protector, resulting in a cleaner and smoother application.

Smooth out air bubbles
Air bubbles can be a common issue when installing a plastic screen protector. These bubbles can make it difficult to see your screen clearly and reduce touchscreen sensitivity. However, there are several methods to smooth out these air bubbles and ensure a clear seal across your device's display.
One common method is to use a plastic card, such as a credit card, to push out the air bubbles. Place your device on a flat surface and apply gentle pressure with the card's edge, working from the centre towards the edges. Push the bubbles out in one direction if possible to maintain a firm grip. It is normal for the bubbles to change shape or move to another position, so continue working with the card until they are completely gone. If you encounter a stubborn air bubble in the corner, try briefly lifting the screen protector's edge closest to the bubble to remove it.
Alternatively, you can use a hairdryer to heat up the area with air bubbles. Be cautious not to overheat your device, as it may damage the components. Apply heat for a short duration, such as 10 to 15 seconds, using the lowest heat setting. Once the adhesive is softened, use a card or cloth to guide the bubbles towards the nearest edge.
If the air bubbles are caused by dust or dirt particles, the hairdryer method may not be effective. In such cases, you may need to remove the screen protector and use sticky tape to eliminate the dust particles.
To prevent air bubbles from forming in the first place, ensure that your device's screen is clean and free from dust, grease, or fingerprints before applying the screen protector. Additionally, follow the manufacturer's installation instructions and select a high-quality screen protector with effective adhesive.
