Your tablet’s screen is not a cast-iron skillet. You cannot go at it with a scrub brush or a spray of Windex. That’s a one-way ticket to a ruined oleophobic coating—the thing that keeps your glass from turning into a smudge city. Instead, think of it like cleaning a pair of reading glasses: gentle, dry, and patient.
If you absolutely need moisture, use a microfiber cloth slightly dampened with a mix of distilled water and a tiny drop of mild dish soap. Never spray anything directly onto the screen. The liquid can sneak into the edges, and then you’re not cleaning—you’re baptizing your tablet.
