Just wondering what the best way to safely get rid of these are. I have a white MacBook that is about 6 months old. I wash my hands alot, but it appears as though the oil on the keys lays on the screen when the laptop is closed. I know there are many topics on here to fix oil stains (I searched). But I want to know the most efficient and safest way to clean them off of the screen, and prevent it from happening again. Thanks.
