You need (2) microfiber cloths, and a plastic grocery bag to store them in.
Get a Microfiber cloth and wipe away any heavy smudges going left to right almost as if your brushing dirt off the screen first, while slowing working your way down the screen from the top to the bottom.
Then switch microfibers to the clean one and you can buff or wipe the screen in any motion you like.
The first microfiber takes off any dirt, or initial grunge or debris. The 2nd microfiber will stay clean, and make the screen look perfect.
I’d keep the microfibers separate and in a bag so dirt cannot get on them.
This doesn’t need to be done very often, and it’ll keep any glass screen from scratching.. It’s easy and straight forward.. 2 microfibers, and a plastic grocery bag to put them in.
Tissue, paper towels, and most other household items will scratch a screen. So it’s important to use Microfiber, or Magic-fiber only. And dirt is the enemy.
