What You'll Learn
Clean with dish soap and water
To clean a phone case with dish soap and water, start by removing your phone from the case and setting it somewhere away from the water. Next, prepare a mixture of warm water and dish soap. The general recommendation is to mix about 1 cup (240 ml) of warm water with 2 to 3 drops of liquid dish soap, but some sources suggest using hot water and increasing the amount of soap to a few drops. Stir the mixture until it becomes soapy.
Once your solution is ready, use a toothbrush to scrub your phone case with it. Make sure to get into all the nooks and crannies, especially inside the case and around the buttons or openings for the camera and charge port. If your case has tough stains, you can apply the solution directly to these areas with a toothbrush before scrubbing. You can also use a cloth or sponge to wipe down the case, but a toothbrush will allow you to reach the smaller spots more easily.
After scrubbing the case, rinse it off under running water in your sink. Pay special attention to hard-to-reach spots to ensure that all soap residue is removed. If there is any remaining debris or stains, scrub the case again with the soapy water solution, then rinse. Finally, dry the case thoroughly with a cloth and let it air dry for at least an hour before putting it back on your phone. To speed up the drying process, wipe the case as dry as possible first, then place it on a clean towel in a well-ventilated area.
Repeat this cleaning process regularly, at least once a week, to prevent your phone case from turning yellow and to remove excess oils and chemicals that can cause material degradation over time.

Use baking soda and water
Baking soda is a mild abrasive that can help remove surface stains from plastic phone cases. It is safe for use on plastic and will not scratch your phone case. Here is a step-by-step guide on how to use baking soda and water to clean your phone case:
Step 1: Prepare the mixture
Mix one tablespoon of baking soda with one cup of warm water in a bowl to form a thick paste. You can adjust the measurements as needed, but ensure the paste is thick enough to adhere to the phone case.
Step 2: Apply the paste
Take your phone case off your phone and place it on a clean surface or in the sink. Sprinkle baking soda generously over the entire case, ensuring all stained areas are covered. Alternatively, use a soft-bristled toothbrush or a paste applicator brush to apply the paste to the yellowed areas of the case.
Step 3: Scrub and soak
Scrub the paste in a circular motion, focusing on the yellowish areas. Let the paste sit on the case for about 10-15 minutes to allow the baking soda to work on the stains. If using a toothbrush, dampen it with water before scrubbing.
Step 4: Rinse and dry
After soaking, rinse the case with running water to remove the paste. Shake out excess water and wipe the case dry with a clean cloth. Pay attention to the corners and openings to ensure all moisture is removed. Let the case air dry completely before using it again. Choose a well-ventilated area for drying, as the case will dry faster in a bright and airy space.
Additional tips:
- For tougher stains, you can repeat the process or try using a mixture of dish soap and water.
- To remove any residual baking soda, wash the case with soap and water or use a disinfectant like rubbing alcohol.
- Regular cleaning of your phone case can help prevent yellowing. Use mild soap and water or rubbing alcohol for weekly maintenance.
- Avoid harsh chemicals and abrasive scrubbing as they can weaken the plastic.

Try hydrogen peroxide
Hydrogen peroxide is a popular method for whitening yellowed plastic phone cases. It is a bleaching agent and a UV stabiliser, meaning it can reverse the yellowing process.
To use hydrogen peroxide to whiten your phone case, start by removing your phone from its case. Then, take a container and fill it with enough hydrogen peroxide to fully submerge your phone case. Place your case in the container and let it soak for 1-2 hours. After soaking, remove the case from the container and rinse it thoroughly with running water. Dry the case entirely before reusing it.
It is important to note that hydrogen peroxide can be corrosive to the skin, so it is recommended to wear gloves when handling it. Additionally, prolonged exposure to the bleach can weaken the plastic, so do not leave the case in the bleach for too long.
Before applying hydrogen peroxide to your entire case, it is advisable to test a small area first. Apply a small amount of peroxide to a corner of your case and follow the above steps. This will allow you to see how your case reacts to the peroxide before fully committing.
Hydrogen peroxide is a great way to remove hardened yellow stains from your phone case and restore its transparency. However, it should be used sparingly and with caution.

Apply toothpaste to yellowed areas
To apply toothpaste to yellowed areas of your phone case, start by removing your phone from its case. Then, apply toothpaste onto a clean toothbrush and gently scrub the yellowed areas in circular motions. Continue scrubbing for a few minutes, then rinse the case under warm water. Finally, wipe the case with a clean cloth and allow it to air dry.
Toothpaste is a handy way to clean a clear phone case that has turned yellow. It mildly abrades and helps remove yellow stains without damaging the case. It is most effective for minor yellowing and is one of the safest methods for any clear phone case.
While toothpaste can help remove minor yellowing, it may not be effective for more serious cases of yellowing. In such cases, you may need to consider other methods or purchase a new phone case.
Additionally, it is important to note that preventing yellowing is always better than trying to remove it. Regular cleaning with mild soap and water or rubbing alcohol can help prevent the build-up of stains and discolouration. Keeping your phone case away from direct sunlight and heat can also slow down the degradation process.

Buy a new phone case
If your plastic phone case has turned yellow, it might be time to consider buying a new one. While there are some methods to try and restore your old case, the results may vary and it can be a tedious process. So, here are some reasons why purchasing a new phone case is a good idea:
Aesthetics: A yellowed phone case can be unsightly and take away from the overall appearance of your device. By buying a new case, you can restore the original look of your phone and even choose a completely different style or design if you want to switch things up.
Protection: Phone cases are meant to protect your device from scratches, dents, and breaks. Over time, the constant exposure to sunlight, body oils, and other elements can weaken the plastic, making it more brittle and less effective at protecting your phone. Getting a new case ensures that your phone continues to receive optimal protection.
Hygiene: The discoloration of plastic phone cases is often caused by a combination of UV rays and exposure to air pollutants and oils from our hands. These same factors can also create a breeding ground for bacteria. Starting fresh with a new case can improve the hygiene of your phone, especially if you opt for antimicrobial or antibacterial cases.
Variety: The market is flooded with a vast array of phone case options, giving you the chance to be adventurous with your choice. You can explore different materials, colors, and designs to find something that truly suits your style. From slim, sleek cases to rugged, durable options, there's something for everyone.
Affordability: Phone cases are generally quite affordable, especially when compared to the cost of repairing or replacing a damaged phone. So, even if you're on a budget, you can likely find a new case that suits your needs and preferences without breaking the bank.
When buying a new phone case, make sure to select the correct model for your phone to ensure a perfect fit. You can often find this information on the packaging or in the product description online. Also, read reviews from other buyers to get an idea of the case's quality and durability.
