I like using decals on my mac, lately I've been using a cute decal of Pikachu where it looks like it's holding the mac apple. I've used this decal for probably a year, occasionally removing and switching colours. But I noticed today when removing it when I washed the laptop case I saw the imprint of the Pikachu on the mac. I only see the imprint when you wash the top case with some water, otherwise the imprint is invisible. Is there any way to remove the imprint, or is the imprint there forever? I'm gonna put on a new sticker anyway and my mac is 3 years old so whatever. But just wondering is there a way to remove the imprint off?
