I have had my screen repaired at one of the cheep asian shops and ever since then i have been getting more and more dust underneath the screen. I can lift the screen up, but would it be a bad idea to wipe the dust off of the LCD and underneath the screen?
Use a camera dust blower to blow off the dust. Clean with professional lens cleaning cloth only when the blower does not work well. NEVER touch the LCD surface with your fingers. It is not possible to repair iPad Air perfectly by anyone except Apple, since the original foam gasket is nowhere to be found on the market. Once opened, the iPad becomes a dust bag regardless of what you do.
I opened mine and the “dust” seems to be stuck inside the lcd and is not possible to get off
