1. Clean the screen with BG cleaning cloth (or fiber soft cloth, glasses cloth) thoroughly. It is better to clean the screen indoors in a neat condition without air flow to reduce the influence of dust. If there is dust on the screen, bubbles will stay between the membrane and the screen which means the failure of sticking membrane. Membrane will become useless when there is dust between it and the screen which damages the silica gel layer of packaging film.
2. Wipe off the stubborn?dirt with BG dedusting paster. If there is stubborn?dirt remaining on the screen, clean the screen with dry cleaning cloth. Wet cloth should not be used. Dedusting paster can stick the dust. So it can be used to clean the screen. Stick dedusting paster back to the original backing paper after using it. Then the paster is recycled.
3. Check the membrane. Take the membrane out of the package. Do not tear off the release liner directly. Put it on the screen of the cellphone, check if the membrane is suitable. Make clear of the place to stick membrane. This will help in later steps.
4. Tear off the first release liner partly. Pay attention to not touch the part of protective membrane exposed with your finger. Each cellphone film is composed of three layers. The first and the last are release liners to protect the protective membrane sandwiched between them.
