Why Does Your Transparent Case Turn Yellow?

Silicone is the material used to make clear phone cases. It’s a polymer popular because it’s inexpensive and quite flexible. These traits make them an excellent phone cover, but polymers, unfortunately, come with the side effect of turning yellow as they age.

Yellowing is a natural process that is accelerated when the transparent phone cases are exposed to too much light, heat, and chemicals. Given how often phones are used, this happens commonly.

This information tells you that the yellowish color of your transparent phone cases is not a stain. It’s a normal part of the material degrading over time. However, don’t worry because you can still counter this issue in various ways.

How to Clean Your Dirty Transparent Phone Case

Follow the steps and tips below on how to clean your silicone phone cases properly:

Gather Necessary Supplies

Begin by gathering your supplies. You might need the following:

  • • Dish soap
  • • Warm water
  • • Old/new toothbrush
  • • Microfiber cloth
  • • Rubbing alcohol
  • • Disinfecting all-purpose cleaner
  • • Baking soda

    Disinfecting All-Purpose Cleaner

    One way to clean your minimalist phone covers (silicone or plastic) is by using a disinfecting all-purpose cleaner. Here is how:

    • 1. Turn off your device and remove your phone case.
    • 2. Get your ammonia-free disinfecting cleaner and spray on the case. Make sure you choose an all-purpose cleaner that works and is safe to use on glass.
    • 3. Let the solution soak the case for a few minutes to kill germs effectively.
    • 4. Get your microfiber towel and wipe down the case (and the phone too if you’ve cleaned it as well).
    • 5. Ensure you wipe them both down dry before you put the phone case back onto your device.

    Dish Soap

    One of the easiest ways to clean your iPhone or Samsung phone cases is using dish soap. It’s readily available and cheap, so it’s perfect if the phone cover you’re cleaning isn’t too stained or yellowing. Here’s how to use it:

    • 1. Make a simple dish soap cleaning solution by mixing a few drops of dish soap with a cup or 240ml of warm water.
    • 2. Get your old or new toothbrush and scrub the phone case while soaking in the dish soap solution.
    • 3. Make sure to get into the nooks and crannies of the phone case and properly clean its interior and exterior.
    • 4. Rinse once you are done scrubbing and dry using a microfiber or soft cloth.

    It helps to repeat this method every few weeks to stave off excess oils and chemicals on your phone case that could cause it to degrade quickly.

    Baking Soda

    If basic cleaning doesn’t help remove the stain off your slim-fit phone cases, you may want to try deep cleaning them using baking soda. Do this following the steps below:

    • 1. Like before, remove your phone case after turning off your phone.
    • 2. For this method, start by making the dish soap solution mentioned before. Soak your phone case in this solution for a few minutes.
    • 3. Next, sprinkle baking soda all over the case and scrub with a toothbrush. Continue until you see all the dirt removed.
    • 4. Once you’re done scrubbing, damp your microfiber towel with some dishwasher and wipe down your phone. Use another microfiber towel to wipe your device dry.
    • 5. Go back to the phone case and rinse in cold water.
    • 6. Like what you did with your phone, use a dry microfiber towel to dry your clear, ultra-thin phone case.
    • 7. Lastly, put your phone case and device back together.

    Rubbing Alcohol

    After cleaning your durable protective cases using dish soap, baking soda, or an all-purpose cleaner, it is time to disinfect them. You can do this using rubbing alcohol by following the steps below:

    • 1. Spray some rubbing alcohol directly on the phone or use a soft cloth soaked in the alcohol.
    • 2. Coat the whole phone case with rubbing alcohol, ensuring you have the case soaked entirely.
    • 3. After a while, dry the case by removing alcohol using a clean, dry cloth.
    • 4. Air out the phone case for about an hour before returning it to your device.

    Using rubbing alcohol not only removes and prevents yellowing but also helps keep bacteria off your device.

    How Often Should You Clean Your Transparent Case?

    To answer your question—it depends. Do you use your phone while eating and does it often get grease from it? In that case, you will need to have your phone case clean pretty often. Otherwise, it would be quite gross to use your device.

    On the other hand, you’re likely to clean your SUPCASE UB Pro case less likely if you work from home. We suggest simply washing your phone cases as frequently as it gets dirty, which helps keep your phone as hygienic as possible.
