How to Clean a Phone Case: Clear, Silicone, Leather & Denim

For most phone cases, a little mild soap, warm water and a soft cloth is all you need. The trick is matching the method to the material, because a clear case, a silicone one, and a leather or denim cover each want slightly different handling, and a couple of common shortcuts (bleach, alcohol, the washing machine) will wreck them. Here's how to clean every type safely, and how to deal with yellowing and stubborn stains. Not sure which type you have? See our guide to the types of phone cases.

The quick version

Find your case type, then read the full steps below.

Case type How to clean Avoid
Clear / TPU Mild soap + water, soft brush; baking-soda paste for yellowing Bleach, alcohol, direct sun
Silicone Mild soap + water; a dab of baking soda for grime Soaking near ports, solvents
Hard plastic Damp cloth + mild soap, then dry fully Abrasive scrubbers
Leather / vegan leather Barely-damp cloth with the grain; condition now and then Soaking, alcohol, heat drying
Denim / fabric flip cover Spot-clean with mild soap on a cloth, air-dry flat Machine wash, soaking, wringing

What you'll need

  • A soft microfibre cloth, plus an old soft toothbrush for seams and cut-outs
  • Mild soap or a drop of dish liquid in warm water
  • For yellowing: baking soda. For leather: a little leather conditioner
  • A dry towel and a shaded spot to air-dry

The whole kit: a soft cloth, a soft brush and a little mild soapy water.

How to clean a clear or silicone case

These pick up grime in the corners and along the edges, and clear ones tend to yellow over time.

  1. Take the case off the phone. Never clean it with the phone still inside.
  2. Mix a few drops of mild soap into warm water and dip the cloth or a soft toothbrush.
  3. Gently scrub inside and out, working the corners and the camera cut-out.
  4. Rinse under a light stream of water, shake off, and pat dry.
  5. Air-dry fully for a few hours before putting the phone back. Trapped moisture is the enemy.

Yellowing on a clear case is usually oxidation from UV light and skin oils. A paste of baking soda and water, scrubbed gently then rinsed, lightens it. Be honest with yourself, though: deep yellowing on a cheap TPU case is often permanent, and at that point a fresh case is the real fix.

How to clean a hard plastic case

Polycarbonate is the easiest. Wipe it with a cloth dampened in mild soapy water, get into the cut-outs with a toothbrush, then dry it fully. Skip abrasive scrubbers, which leave micro-scratches that dull the finish.

How to clean a leather or vegan-leather case

Leather and vegan leather (like the tan trim on our covers) do not like water sitting on them.

  1. Wipe with a cloth that's barely damp, not wet, moving with the grain rather than in circles.
  2. For a mark, add the tiniest bit of mild soap, wipe, then go over it again with a clean damp cloth.
  3. Dry with a soft towel and let it air-dry away from heat and direct sun.
  4. Once in a while, a small amount of leather conditioner keeps it supple and stops it cracking.

Never use alcohol, sanitiser wipes or harsh cleaners on leather, which strip the finish and dry it out.

How to clean a denim or fabric flip cover

A denim flip cover (like ours) is woven fabric over a frame, finished with a tan leather trim, so treat it as a mix of the two.

  1. Brush off loose dust first.
  2. Spot-clean marks with a cloth dipped in mild soapy water. Dab, don't soak. Work gently so the weave doesn't fray.
  3. Wipe the tan leather trim separately with a barely-damp cloth, following the leather steps above.
  4. Press out moisture with a dry towel and air-dry flat, in the shade.

Do not machine-wash or soak a flip cover. It has a rigid inner tray and a magnetic strip; soaking warps the frame and can weaken the glue. Spot-cleaning keeps the denim looking new for far longer. Ours are built with a tan vegan-leather trim that wears in rather than out, so a quick wipe now and then is all they need.

What not to do, ever: no bleach or alcohol (strips colour and finish), no washing machine or soaking (warps the frame, ruins leather), no hair-dryer or direct sun to speed drying (cracks leather, fades fabric), and never clean a case with the phone still inside.

How often should you clean it?

A quick wipe once a week keeps oils and dust from building up; a proper clean once a month is plenty for most people. If you cook, travel or work outdoors, do it more often, since grime that sits in the seams is what ages a case fastest.

Frequently asked questions

How do I remove yellowing from a clear phone case?

Scrub it with a paste of baking soda and water, then rinse and dry. That lightens surface oxidation, but deep yellowing on a cheap TPU case is usually permanent, and a new case is the real fix.

Can I wash my phone case in water?

A clear, silicone or hard plastic case can be washed in mild soapy water and air-dried fully. A leather case should only be wiped with a barely-damp cloth, and a flip cover should be spot-cleaned, never soaked or machine-washed.

How do I remove ink or pen marks from a cover?

Try a cloth with a little mild soapy water first. On leather, keep it minimal and wipe with the grain. Avoid alcohol or solvents, which often lift the colour along with the ink.

How do I clean a leather or vegan-leather case?

Wipe with a barely-damp cloth moving with the grain, dry with a soft towel, air-dry away from heat, and condition it occasionally. Never soak it or use alcohol-based cleaners.

Does a denim phone cover fade or wear out?

A well-made denim cover with a vegan-leather trim ages slowly and softens rather than cracking. Spot-clean it and keep it out of prolonged direct sun, and it holds its colour for a long time.
