I bought an ibook and I just stuck it in the plastic antistatic bag until my sleeve came via the mail. The adhesive seems to got on the back of it and now is brown and dirty looking and I tried using Iklear but it did not take care of this. I can use my fingernail and take it off but it is really tedious. Also I have some nicks and I'll try to get pictures up in a day or so to show you what i mean. Any ideas?
