Second step is with the Metal Polish. Get a clean Dirty Deeds microfibre cloth and apply a 10cm dollop onto the cloth and then apply, again onto a small section of the glass and in a circular motion. Feel free to get a little bit aggressive with it, as this action breaks the diminishing abrasive down, making it more effective and giving you a kick ass clean screen! After polishing for about a minute, remove with a clean side of the Dirty Deeds cloth. Then when the entire screen is done, give it a final clean with the Naked Glass cleaner and wipe clean with the microfibre cloth so you can inspect it and see if it's done.
