I've been using Swifter cloths which I think are Microfibre to clean it and a smooth cloth with water but it doesn't work well and there is a huge smudge at the lower left area of my T.V and it is getting annoying to look at so I stopped cleaning it with those when I wipe it with microfibre cloth the smudge won't go away
Can someone please help me figure out a way to get rid of the smudge
