Short answer
Steam up the bathroom, then: alcohol wipe to remove oils, microfibre cloth to dry, dust sticker over the whole screen under a bright light. Fit the protector straight away, before new dust lands.
The routine
- Steam. Run a hot shower for three to five minutes; airborne dust settles.
- Alcohol wipe. Removes skin oils that stop adhesive bonding.
- Microfibre dry. Wipe in one direction until no streaks remain.
- Light check. Hold the phone under a light or use a torch at a low angle.
- Dust sticker everything. Dab the whole screen, not just visible specks.
- Clean the edges and earpiece. Lint here gets pulled under the adhesive.

Questions people ask
What should I clean my screen with before a screen protector?
An alcohol wipe to remove oils, a microfibre cloth to dry, then dust stickers.
Why steam the bathroom before fitting a screen protector?
Moisture in the air helps airborne dust settle, so less lands on the screen.
