How to Clean a Plastic Phone Case

How to Clean a Plastic Phone Case

Although plastic phone cases are relatively low maintenance, they can be difficult to clean correctly. Unlike other materials, such as leather, plastic is susceptible to wear, discoloration, and warping.

Following these simple steps will ensure your case is as clean as possible. The best part of this method is that it only takes a few minutes, and your case will look as good as new!

Step One: Gather Your Supplies

You will need the following:

  • Paper towels
  • Mild soap, such as hand soap or dish liquid
  • Water
  • A dry towel or cloth
  • A toothbrush or sponge

Step Two: Mix Soap and Water

Mix the soap and water in a bowl. Add mild soap to warm water, mixing until the solution is frothy.

Remove the cover from your phone carefully and gently so as to not damage your case. For especially dirty phone cases, soak the case in soapy water for 10 minutes before moving on to the next step.

Step Three: Gently Scrub Your Phone Case

Now that you've soaked the phone cover in water, it's time to scrub it down.

Take your toothbrush and fill a small bowl with warm water. Dip the toothbrush into the bowl of water and drench it thoroughly with water—you'll also want to give this brush a thorough rinse before using it to clean!

Use this wet toothbrush to gently rub over all of the surfaces of your phone case, including any little crevices or cracks where dirt may have gotten caught. Do not press too hard, as rubbing hard will wear away the plastic over time and cause permanent damage to the finish! If necessary, repeat these steps until all parts are clean.

Step Four: Rinse the Case Off

Now that you’ve wiped the case off, it’s time to rinse it. Make sure there is no soapy residue left behind. Rinse thoroughly with water and let dry for about 30 minutes.

Step Five: Dry Thoroughly

After you've done the initial cleaning, make sure that you dry the case thoroughly with a microfiber towel. Before putting the phone case back on your device again, set it in a safe and dry area to allow it to get some airflow and ensure no water is left to damage the fragile electronics inside your phone.

The heat that blows from a hair dryer is too hot, and that high heat could damage the structure of your case, so don’t use one to speed up the process. Instead, use a fan that blows cool air to dry your case faster if you don’t have an hour to let it air dry.


Cleaning a plastic phone case is easy. Simply wash it with soap and water, rinse well, and dry it thoroughly before using it again. You can use a damp cloth to wipe the case if you don't have time to do an in-depth cleaning immediately.

With the proper care, you can rely on Casely's high-quality polycarbonate plastic phone cases to continue protecting your phone and adding style to your everyday looks.
