I recently purchased a case for my Macbook from techshell.com, which is awesome. Since it covers the outside of the Macbook completely, I removed my InvisibleShield, which I had been somewhat unhappy with because I managed to get some dust stuck to it during application. My problem is, despite InvisibleShield's claims, there is some residue left on my Macbook (fortunately it is just in a few spots and not on the entire thing). The only cleaning product I have on hand is iKlear, which didn't do a thing for it. Can anyone think of something non-abrasive I can use to get it off? It is much like the stucky residue left when you remove a sticker.
