Howdy! This is my first post. I am the proud owner of a new iPad 4 with retina display. I elected to go with the black 16GB wireless model. This is my first iPad or tablet. So far, I love it! I figured I'd like it quite a bit, but I truly am enjoying it more than I thought I might. Anyhow, I am wondering what the best way to clean the back aluminum part of the iPad is. I am extremely careful with all my stuff and wash my hands before I handle my iPad (or any other high-end device). Despite my efforts, I noticed that the aluminum on the back of my iPad has smudges from my fingers. I went online and did some research on cleaning it. I took the advice of the Apple website and got a clean, lint-free cloth (a soft, smooth t-shirt) with just a tiny bit of water and tried cleaning the back portion of the iPad. While it seems that the fingerprints do go away, I noticed the dampness seems to smudge the aluminum further. After a few seconds, I go over it again with the dry portion of the t-shirt. This helps a little bit, but the smudges still remain. So, I'm wondering if this is just the way the aluminum is and if I'll never be able to get it perfect, or if there's a better way to clean it and prevent the smudging? I ordered the Apple Smart Case, which I'll put on it as soon as it comes in. Thanks in advance!
