hi. i'm using the new MacBook white for a month or so already but i've gotten some pretty stubborn stains on the trackpad. after trying a combination of damp cloth and soap, i went to get an iKlear, which was recommended by the sales officer. however, iKlear doesn't seem to work at all. in fact, it actually made the stain spread all over the trackpad. i really need help in cleaning this stain. it's such an eyesore!
