Hydrogen Peroxide

How about putting a classic combination of hydrogen peroxide and UV light to the test? Don’t worry about where to get the chemical. If you can’t find it, go for an H2O2-based cream. Also, get a light source that can emit UV rays. UV rays provide a safe type of radiation that breaks down chemical bonds. You can use a UV nail dryer too.

Yes, you can erase some of those stains off. For a case with matte finishing, consider this a viable option. Alternatively, the method should also work on a silicone case with a smooth texture. Simply, erase stains and marks from your case as you would a book.


Sunrays tend to whiten anything exposed to it. While we have no ideal reason why that happens, what we are certain of is it’s workable for a phone case. Place it out and let it bask in the sun. To avoid uneven lighting, keep changing positions as the sun shifts from East to West.


Have you ever considered scrapping off the top layer of yellow cases? It is possible thanks to sandpaper. We recommend it for a transparent phone case. Although it will most probably not give you a seamless clean, your case will be a few shades brighter.

Sand your case then wipe it with a damp cleaning cloth. Once done, it will be good to go.

Get a New Phone Case

If you try all these and nothing seems to stop or reverse the yellowing process, it might be about time to get a new one. For an upgrade, give preference to non-yellowing cases when buying. To give it a longer life span, consider cleaning and disinfecting it regularly to prevent degradation.

The privilege you get by doing so is you prevent debris and dirt from setting in. Consequently, you will only deal with light stains which will come off easily most of the time. In addition to doing it frequently, do it accurately. Avoid preventable mistakes like using wet or semi-dry phone cases.

On the other hand, clean and bacteria-free phone cases are beneficial to your health too. On average, we spend three hours and 15 minutes on our mobile phones every day. To put this into perspective, for a 6-inch screen dirty phone, you directly interact with over 200,000 germs.
