Why does dust get in? First, let's find out the cause.

Dust in the air
Although it is invisible to the naked eye, there is a lot of fine dust floating in the air. When you move your hands during the application process, the dust gets stirred up and ends up on the screen.
Dust from clothes and hair
Wool and lint-prone clothing tend to produce lint, which can fall off during work. Dust can also be found in hair.
Electrostatic adsorption
Smartphone screen protectors are made of resin, which is prone to static electricity. Friction attracts dust. This is especially important when using nylon clothing. Reducing static electricity and friction can significantly prevent dust from adhering to the screen.

No mistakes! 5 steps before application to ensure zero dust
To ensure successful application of the film, proper preparation before application is crucial. Follow these five steps to prevent dust from getting in.

Wash your hands and get dressed
Wash your hands thoroughly to remove dirt and dust. It's a good idea to change into clothes that don't easily pill (such as cotton). Create an environment that is less susceptible to dust.
② Working in a humid place such as a bathroom
Taking a bath after a shower is the best environment for working as it reduces the amount of dust in the air.
3. Clean your smartphone thoroughly
Remove oil with the included alcohol wipe, then wipe dry with a microfiber cloth to carefully remove even the most invisible dust particles from the screen.
④ Eliminate static electricity
Using an anti-static sheet will prevent the film and smartphone body from attracting dust.
⑤ Final check with dust removal sticker
Immediately before applying, thoroughly remove any fine dust from the screen and film surface using a sticker.
💡 Just by keeping these five things in mind, you can significantly reduce mistakes when applying the stickers!
