Wash and dry your hands
Clean the screen and protector with a microfiber cloth
Use a dust sticker or tape to remove any dust particles
Lift the nearest edge of the protector slightly
Reapply the protector slowly and evenly
Push bubbles toward the edge with a credit card or squeegee
Wrap the card in a soft cloth to avoid scratches
Press from the center outward
Use a pin only for tiny trapped bubbles, then smooth them out
Leave the protector alone for 24 to 48 hours if it is a self-healing type
Replace the protector if bubbles are caused by dust or damage that cannot be removed
