Depending on how thick your phone case is, you may also want to remove it. If it’s super bulky, it could be hard to clean the edges of the screen thoroughly.
A microfiber cloth would also work well for this process. You should never use paper towels or tissues to clean your screen. They can leave behind little bits of lint or could even potentially scratch your screen.
When applying the cooking oil to the cloth, just a little dab will do. You don’t want to use a dripping-wet cloth and risk getting oil into your speaker or charging port. To clean off the oil afterward, wipe the screen down with a clean microfiber cloth several times.
Make sure to put the cap back on the rubbing alcohol or move it away from where you’re working. You don’t want it to fall over and spill onto your phone! You can use nail polish instead of rubbing alcohol if you prefer.
Once you’re done cleaning your screen, you may want to wipe it down several times with a clean microfiber cloth. Be careful to not get any mayonnaise in the speaker or charging port.
Don’t hold the hairdryer against your phone or point it at one spot for too long.
You may also find it useful to use a toothpick. Just be sure to angle the toothpick up so that it doesn’t scratch the screen when it slips under the protector.
Doing this slowly should also help prevent the adhesive from sticking to your screen.
If you notice adhesive sticking to your screen, try gently pushing the protector back into place and removing it even more slowly. The hope here is that the adhesive will stay with the protector instead of your screen.
