Cerium oxide polishing powder is an excellent polishing material.

Smartphones are really easy to use thanks to their large touchscreens that dominate the entire front of the handset. Toughened glass offers some protection, but even this isn’t enough to completely protect your handset and you can easily get scratches.

Here, we’ll show you how to polish out scratches on glass screens. Before you start, you should know that polishing a scratch out will also remove any coatings on the screen, such as an oleophobic coating, which lets you fingers move smoothly across the surface. To create an even finish, you may wish to polish the entire front of the screen to remove all the coating

To begin with you’ll need a suitable polish. We’re dealing with glass screens only (check your phone’s specs to make sure it doesn’t have a plastic screen), so you need a tough polish. We recommend Cerium Oxide Polishing Powder , which comes as a powder that you need to mix with water.

Cerium Oxide Polishing Powder, also called cerium polishing powder and rare earth based polishing powders, high suspension in water and quick polishing when used with any felt polishing pad, removes hairline scratches, lime scale and adhesive residue.


Use masking tape to mask off the area that you want to polish. It’s important to cover any areas where the cerium oxide compound can get into the phone or clog it up. Take care around buttons, speakers and microphone inputs.



Put a dab of Cerium Oxide Polishing Powder  on to a polishing cloth. Rub it vigorously in circles over the scratch, until the compound is fully expended and has dried up. Use your second cloth to remove the remainder of the cerium oxide from the phone. Check carefully to see if the scratch is still visible; if it is, repeat this step. It can take a while: we took over an hour to get a scratch out of an iPhone 4S. Repeat Step 1 and 2 for all major scratches.



With the scratch gone, you can focus on the rest of the phone. A quick polish of the rest of the screen will give you an even finish. While it may remove the phone’s coating, we’d rather have this than the scratch. Remove the masking tape from the phone, bar that covering the buttons, then put a bit of Cerium Oxide Polishing Powder on your polishing cloth. Use circular movements over the phone’s entire screen. A good few minutes should do the trick, focusing on the minor scratches your handset may have.



Take your second cloth and polish off the remainder of the Cerium Oxide Polishing Powder . Remove the masking tape from your phone. Next, you may want to clean the screen. A microfibre glass cleaning cloth with a dab of water on it usually does the trick. Once done, you’ll have a nice, clear, scratch-free handset once again.
