I don’t know about the alcohol part but I do know it’s important what you use along with the liquid. You don’t want to inadvertently use something that can cause even minor scratching.
FWIW I’ve been getting excellent results for years with plain bottled water (to eliminate excess minerals) and coffee filters.
I just cut a coffee filter in quarters and use it that way. I also use this for my iPhone and tablet screens as well as my computer screen.
Gets everything cleaned up great with never any damage and some things I always have around the house.
In years past I’ve also used those small alcohol swabs for my phone until I realized that water and the coffee filter did the job just as well.
And after you use the filter damp, then just using it dry to get any excess moisture off leaves everything streak free and looking like new.
I was pleasantly surprised to find this worked well for the phone and tablet screens especislly because they can get pretty schmutzy because of the natural oils from one’s fingerprints.
When I first read about using coffee filters for this purpose, I wasn’t expecting much but it’s the best method I’ve found so far.
I don’t really know what value alcohol brings to the equation other than the fact that it evaporates quickly and supposedly streak free. But using the coffee filters along with water works just fine and no streaks at all.
This is similar in principle for using newspapers for cleaning windows and car windshields. Excellent results. Simple and no fuss. Shiny and good as new.
