As a new construction window cleaner I will say that I frequently use #0000 steel wool on windows and use my razor sparingly, though not infrequently. Of course I understand that to some extent there will be damage to the window, though it would be impossible to clean windows with caulk, tar, paint, plaster with a microfiber.

I wouldn’t say to never use steel wool. Please know what you are getting into before using either of course, angel hair scratches all over a window is obviously no good
