I've had my 2010 Macbook since it launched and this thing just attracts grime and scratches. I literally left my Macbook on my desk for a day and all of a sudden it has two jagged scratches near the apple just by sitting on desk! Now after that happened, I bought a Caselogic sleeve to protect it when not in use but now I have a green stain near the power indicator on the side of the palm rest. I tried cleaning it off with soap and water, it didn't work. Then I googled it and I heard toothpaste might take out stains, so I tried that and it came off now but then it returned a couple of days later when I wasn't using the sleeve, so I figured it's not the problem. Cleaned it again with toothpaste and now there's a just a faint green stain I just can't get rid of. Is there a better way of protecting my Macbook?
