Uncommon Hacks You Can Use To Clean Your Phone Case

Not every method you can use is so conventional. In some cases, you can try other hacks which very few people would ever think of. Remember, the aim is to get rid of that annoying yellow, so whatever works to get the job done. Let’s look at some examples:

Person holding a new clear case for iPhone11


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


Sunrays tend to whitening 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 lightening, keep changing positions as the sun shifts from East to West.


Ever think of scrapping off the top layer of your yellowed case? It is possible thanks to sandpaper. We recommend it for clear plastic phone cases. Although it will most probably not give you a seamless clean, your case will be a few shades brighter.

Sand your phone 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 works, it might be about time to get a new one. For an upgrade, give preference to non-yellowing phone 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, a clean and bacteria-free phone case is beneficial to your health too. On average, we spend three hours 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.

Scary, right? Ultimately, aim to clean your phone case as frequently as you can and it will serve you back. Once it has served its due time, get a new one to maintain your phone in mint condition.
