Keep your phone case looking fresh and lasting longer with simple cleaning steps. Learn how to remove yellow stains and care for silicone cases.

Quick answer

Clean your phone case weekly with mild soap and warm water, and dry it completely before putting it back on. For yellow stains on clear cases, a baking soda paste or diluted hydrogen peroxide can help restore clarity.

Why regular cleaning matters

Phone cases trap dirt, oil from your hands, and dust from pockets. Over time, these residues can scratch your phone's back, cause discoloration, and even harbor bacteria. A quick weekly wipe-down prevents buildup and keeps your case looking new longer.

Clear cases are especially prone to yellowing due to UV exposure and heat. While no cleaning method reverses UV damage entirely, regular cleaning slows the process and removes surface stains that make the case look older than it is.

What you'll need

Most phone cases need only mild dish soap, warm water, a soft cloth or sponge, and a toothbrush for crevices. For tougher stains, keep baking soda, white vinegar, or hydrogen peroxide on hand. Avoid bleach, alcohol wipes, or abrasive scrubbers—they can strip coatings or dull the finish.

Step-by-step phone case cleaning routine

Remove the case from your phone: Take the case off your phone completely. This lets you clean every surface and allows the phone to air out. For tight cases, start from one corner and work your way around gently. Check for debris trapped between the case and phone—those tiny particles can scratch your phone's back.
Wash with mild soap and warm water: Mix a few drops of mild dish soap in a bowl of warm water. Dip a soft cloth or sponge and wipe the entire case inside and out. Use a soft toothbrush to scrub corners, button cutouts, and the camera bump area. Don't soak the case for more than a few minutes—prolonged exposure can weaken the material or fade colors.
Rinse and dry thoroughly: Rinse the case under cool running water to remove all soap residue. Shake off excess water and pat dry with a lint-free cloth. Let the case air-dry completely for at least an hour before putting it back on your phone. Putting a damp case on your phone can trap moisture, leading to fogging under the screen or damage to charging ports.
Treat yellow stains on clear cases: Make a paste of baking soda and water, or mix equal parts hydrogen peroxide and water. Apply to stained areas with a soft cloth and let sit for 10–15 minutes. Rinse and dry as usual. Repeat if needed. This method works best on surface stains. Deep UV yellowing is permanent—prevention with regular cleaning is more effective than trying to reverse it.
Disinfect occasionally without damaging the case: For a deeper clean, wipe the case with a cloth dampened with 70% isopropyl alcohol. Avoid soaking or using higher concentrations, which can dry out or crack silicone and TPU materials. Let it air-dry completely. Test on a small hidden area first—some coatings or finishes may react to alcohol even at 70%.
