Hi, I would like to know the safest and the best way to keep Dell's case black and bright. Mine's 15 months old and looks kind of dingy black, almost gray as if faded....probably from wiping it down too often. Living in the Arizona desert doesn't help, even keeping it covered when not it use. I have a new, second one now and I'd like to keep it looking new. Also...OK to use Windex on my CRT screen? Is there a safer way? Thanks Mike....Picture Rocks, AZ
