My MacBook screen has been getting progressively worse - total staingate! I have used mild “screen” wipes available in our office - no help. After watching a YouTube video of a guy removing the coating with Listerine, I opted to try an '''''anti-bacterial all purpose wipe''''' (this was a no-name brand) similar to Lysol. I had nothing to lose! '''It worked'''. Screen is 99% better than it was. I reckon one more treatment will do the trick. It took about 5 minutes to clean it.
