I work with my tablet a lot and the screen is rather dirty all the time. I try to use different removers or cleaners for the screen, but the effect is temporal and not for a long time. What do you use? May be any personal hints?

My choice is the result of custom synthesis https://ereztech.com/product/boron-phos ... 3308-51-5/ that I ordered once a month. I need it for every my screen and happy to find it half a year ago. It is so great and effective that I do not imagine my devices without it.
