Quick Answer

Use a dry microfiber cloth first, then a slightly damp one with plain water if needed. Avoid paper towels, alcohol, and abrasive cleaners—they can strip the oleophobic coating or scratch the glass.

Why Cleaning Method Matters

Screen protectors, especially tempered glass, have an oleophobic coating that repels oil and makes fingerprints easier to wipe off. Using the wrong cleaner can degrade that coating over time, leading to more smudges and reduced touch smoothness.

Abrasive materials like paper towels or rough cloths can leave micro-scratches on the glass, which become visible when the screen is lit. Even if the protector is replaceable, you want to extend its life and keep your display clear.

What to Avoid

Skip alcohol-based wipes, ammonia cleaners, and household glass sprays. These can break down the coating and cause cloudiness. Also avoid using your shirt or tissue—they often carry dust or fibers that scratch.

If you have a Belkin UltraGlass protector, the same rules apply: stick to dry and damp microfiber cloths to protect the ultra-glass surface and its clarity.

Step-by-Step Safe Cleaning Process

  1. Power off and inspect: Turn off your phone and hold it under a bright light to see smudges, dust, and streaks clearly. This helps you target the dirty spots without wiping the whole screen repeatedly. Check for any loose particles that could scratch when wiped.
  2. Dry wipe with microfiber: Use a clean, dry microfiber cloth to gently wipe the screen in a circular motion. This removes most fingerprints and light dust without needing moisture. If smudges remain, move to the next step; do not press hard.
  3. Dampen cloth with water: Lightly dampen a corner of the microfiber cloth with plain water (not soaking wet). Wipe the screen again, then use the dry part of the cloth to buff it dry. Never spray water directly on the phone or protector.
  4. Handle stubborn spots: For dried-on residue, use a tiny drop of mild soap (like dish soap) diluted in water on the damp cloth. Wipe gently, then thoroughly dry with a clean microfiber section. Avoid any soap with alcohol, bleach, or fragrances.
  5. Reapply coating if needed: If the oleophobic coating has worn off (screen smudges more easily), consider a coating repair kit or replace the protector with a new one like the Belkin UltraGlass for restored clarity. Regular gentle cleaning helps postpone coating wear.
