Why Is My Otter Box Armor Series Leaving Marks On My iPhone 5?

I have an iPhone 5 and I also have an Otter Box Armor Series on it. When I look at the back of my iPhone the rubber from the Otter Box will leave marks onto my iPhone 5. Why does it leave marks and what can I do to get rid of the marks?

You're in the wrong category. This is for Home & Garden. You should try Consumer Electronics, then cell phones sub-category.
