Yes, oil from our fingers. Also, that contains a small amount of some type
of acidic something or other. Over time, I imagine that this (something or
other), is what is etching your screen. Most times I'm able to remove most
of the outline. But If I lok closely, I can see a faint outline still there,
doesn't affect my work, so no worries.
