White smudges on M1 macbook air's screen

Got my macbook air 10 days ago. Since the day I got it I have noticed that it attracts lots of fingerprints, grease on the keyboard, and dust; and if I try to wipe them they will create smudges all over the screen. Then I brought it to my local apple store. An employee cleaned my screen and recommended "Whoosh!" which is a cleaning tool they use.

My mac's screen was quite dirty today so I decided to try the recommended cleaning tool but it made the smudges look a lot more worse... and they are driving me nuts.

I just want to know how to get rid of them and if most people have this problem with their M1 macbook air or retina screen. Also should I return it if it is not a common problem? I will appreciate any input.
