How To Clean A Clear Phone Case

by craftyclub

There is nothing worse than a once clear phone cover developing an unappealing yellow tint. It’s something we’ve all undoubtedly experienced at some point – and despised.

However, it is as disheartening when a new phone case becomes yellow. Clear phone covers are typically silicone, a popular material due to its low cost and flexibility. Unfortunately though, when these polymers age, they turn yellow. This is a natural process that is usually accelerated when there is constant exposure to heat such as sunlight and your phone’s own heat.

The yellowing is part of the material breakdown, not just a stain so it’s much harder to remove than a simple rinse under the tap.

Luckily, there are several methods you can use to remove a nasty yellow stain from your phone case. 

How To Clean A Clear Phone Case

Dish Soap and Water

It may appear to be a simple hack, but lo and behold it breaks down any residue it comes in touch with. As a result, it’s an effective cleaning solution for a yellowing phone case. 

Follow the instructions below to use this method.

Add a couple of drops of dish soap to lukewarm water and mix it until soapy. Grab a clean toothbrush and use the solution to clean the insides of your removed phone cover. 

Remember to check the ports/buttons in the corners and any gaps. Dunk the case in the water repeatedly as you thoroughly clean it.

Drain the filthy water and rinse the case with clean water to remove residual soap.

Towel dry the case with a microfiber cloth and allow it to air dry entirely. Make sure your phone case is entirely dry before reapplying it to your phone; else, it may be damaged.

Baking Soda

You can remove most stains on plastic phone covers with baking soda, but not all of them. Scatter baking soda around the surface of your phone case. 

Scrub the baking soda into the spots with a wet toothbrush, carefully covering the whole phone case. Rinse your phone case to remove the baking soda. 

Make sure to wash your phone case with water and some soap to eliminate any remaining baking soda. In a bowl, combine a few drops of dish soap with 1 cup of water. 

Scrub your phone case with soapy water using the toothbrush. Rinse and dry the case with soapy water and a gentle towel.

White Vinegar

How can we talk about baking soda without also talking about white vinegar? After all, the two work well together, which is why they are so effective at cleaning. 

Because of its power and acidity, white vinegar is an excellent natural cleanser. It may simply remove limescale and sterilize your surfaces. Here’s how to apply it on a transparent phone case.

Locate a small jar or dish large enough to hold your phone cover. Place the empty case inside, with something heavy on top, to keep it in place. Just make sure it’s not metal or rubber, so it doesn’t rust.

Use two teaspoons of baking soda and spread it over the case, then slowly pour one cup of white distilled vinegar on top. Expect it to bubble at first; this is a normal part of the cleaning process. 

If the case isn’t completely immersed, add extra vinegar as needed. Allow soaking for a few hours. When the timer goes off, properly rinse your case. 

Dry with a microfiber cloth and allow to air dry entirely before reusing the case.


If your phone cover is filthy, use a rubber eraser to clean it. Scrub at the markings with the eraser along the side of the phone cover to remove them.

To remove the eraser residue, wash your case with dish soap. Wash the case with running water and then dry it with a soft towel. Before reinstalling your phone case, make sure it is totally dry.

Alcohol To Disinfect

Disinfecting your phone regularly is an excellent habit to develop. It’s also a good way to keep your phone case from yellowing.

It may, however, discolor certain transparent cases, so verify with the manufacturer or test the rubbing alcohol in an inconspicuous area before using it on the entire case.

Coat the phone case with rubbing alcohol and leave it on for a while. Use a cloth to scrub gently then remove it with a clean, dry towel.

Allow it to dry for an hour before replacing it on your phone. Even if it does not erase the yellowing, it will be bacteria-free and more sanitary.

Hydrogen Peroxide

If you’re desperate, you can attempt restoring a brown phone cover with hydrogen peroxide. However, be cautious since it may harm some phone cases. However, it will disinfect your case.

Fill a small container halfway with water, then add half a cup of hydrogen peroxide. Please insert your phone case and ensure it is coated with the solution.

Soak your phone case for several hours or until it is completely clean. Rinse and dry your case with a gentle cloth. Wait an hour before replacing your phone in its case to ensure that it is entirely dry.

Toothpaste And Paint Thinner

If the stains are so stubborn that none of the methods above work you can resort to using paint thinner and some paste. Coat your phone cover with the paste first, then clean it with steel wool. 

Then, rinse off the toothpaste and coat it with paint thinner. Work on it again with the steel wool. Finally, use water to remove the paint thinner.
