I mentioned waxing your phone with nano wax or teflon wax. I use nano.
Someone suggested using a plexiglass cleaner. Plexiglass cleaner will destroy your phone. It works by removing the scratches and marks off the screen. Doing so will thin the screen and all other plastic. Do not use any plastic polish on your phone, it will mess it up bad!! When I wax mine, i first turn it off and remove the battery. Then I take a qtip and clean the inside of the phone gently to remove dirt and grime from the camera lense and the battery area.
Then I clean the back cover with a cotton ball dampened with water and eye glass cleaner. Let it dry. Use a cotton bal dampened in nano wax and apply it to the back cover. Let dry and wipe it to a shine. Use a piece of screen protector and cut it to fit over the camera hole on the back cover. Use a cotton ball dampened in eye glass cleaner and clean the rest of the phone. DO NOT GET PHONE SOAKED, JUST WIPE IT CLEAN! Let it dry and then do the same for the rest of the phone as done withthe back cover. Please do not spray anything on your phone!! When you clean the screen, hold the phone upside down and clean it, dirt will fall off and it prevents the phone from getting moisture in it. Always use a screen protector.
