I tried PlastX because I have the same exact problem as you and it didn't make a difference. I started with just a small corner of a microfiber towel and a small area of the scratch, but then got more aggressive once I knew it wasn't scratching up the rest of the screen, but it made no difference.
I also tried the pencil eraser tip and the petroleum jelly trick as well...no dice. Prolly only option is to change out the screen if you ever see one cheap on Fleabay. I decided at that point not to mess with it any more. Only really noticeable when the screen is off.
good luck,
