I purchased a product called Whoosh! at the Apple store and was told it was the only safe product Apple recommends to clean retina screens. The weird thing is that Whoosh isn't sold at Apple store anymore and I'm wondering if it's because of the residue/streaks/film I'm seeing when I use it?<p>http://imgur.com/dWqtPvM
I seem to get tons of lint particles on the screen no matter what kind of cloth I use (I tried microfiber, tissue paper, paper towels, etc). Lately I've been using a clean white sock (with no liquid) and it works alright. I just buff out the smudges rather than trying to clean them off with a liquid.<p>Cleaning it in daylight helps a lot as well, much easier to tell what you're doing.
Be extremely careful when washing your Macbook screen.<p><a href="http://www.staingate.org/" rel="nofollow">http://www.staingate.org/</a><p>This recently happened to someone I know, after attempting to clean the display. It is not covered under warranty, and there is no fix.
