I bought a early 2006 black MacBook off a family friend awhile back and it was practically brand new. Since I have been using it I noticed the keys and the trackpad on it are starting to get a weird feeling. The feeling is sort of like grease or something on the trackpad and keys. I wash my hands before using it, but I guess just from the oils on my hands have caused this. I have included pictures below trying to show what I am talking about. I have read around online on ways to clean it and everyone has suggested many different things and I've tried a few and nothing has worked. I used water and windex mixed with water and that cleaned it up a little bit, but didn't help much. I was just wondering if anyone had any suggestions so to a method that works for cleaning the trackpad and keys to remove whatever it is on there. Thanks a lot.
