I have a iphone 6 and want to make it as neat as possible before I retire it. I have light damages on it. The only replaced thing is the battery. I have a very light ring around my apple logo from the case and am now covering it to prevent it getting worse. I have a bit of water damage at the top left corner (brighter patch) from a snowball that was thrown on it. I also have quite light long scratches on my display which reflects light. How do I go about fixing these minor problems without spending much money?
Most of your issues have to do with the screen so if you want to look good prior to selling it or giving it someone, I would suggest you replace the screen. You can do this yourself by following this guide.
