Mhmph! Well, my Glossy SR MBP screen was a little dusty after the last couple of weeks, so to keep it looking spotless I used my trusty iKlear and accompanying cloth. iKlear has worked fantastically well on all my matte Mac screens, so when I read on the bottle that it was also recommended for glossy I didn't think twice before applying it. Anyway, it looked, how I'd describe as, greasy. It took about 15 minutes of polishing to remove it all, the last 5 being with my 30" ACD cloth (great cloth comes with these) as the iKlear one just seemed to be moving the iKlear 'grease' around. Thankfully it all looks spotless now, as best I can tell in this light, but I certainly wont use iKlear on my glossy MBP screen ever again! Edit: For the smart-arses who think I can't read, here are the instructions as written on the bottle, which I followed! 1) Turn off electronic device. 2) Lightly mist screen with iKlear (one pump per square foot). 3) Spread solution evenly using corner of Micro-Chamois or Micro-Fiber Cloth. 4) Polish off solution using horizontal and vertical strokes.
