You’ve always “needed” a soft cloth to clean glass of any kind. This is not a downgrade, it’s doing the best you can to preserve things.

I wonder how many people in these threads also use vinegar to clean their led/lcd tvs and monitors? If you are, stop it. It’s also not a downgrade to not use acid.

As I said in another comment. Most clothing now has plastic in it, that is way more abrasive than pure cotton.
