It is one of carbon's great arguments: unlike silicone that yellows or leather that demands regular care, a genuine carbon fiber case requires very little maintenance. But “very little” does not mean “none” — and above all, a few everyday products can damage the resin that protects the fibers.
Here is the complete guide to the right moves, the products to ban and the special cases, so your case keeps its original look as long as your phone.
Why carbon is so easy to live with
What you touch on a carbon case is not the raw fiber: it is the epoxy resin that impregnates and protects it — the same family of resins aerospace has used for 40 years. This surface is non-porous: it absorbs neither sweat, nor skin oils, nor liquids. Result: dirt stays on the surface and comes off easily — where silicone soaks it up and leather stains.
It is also why carbon does not yellow or discolor over time, as we detail in our phone case materials comparison.
Routine cleaning, in 4 moves
- 1. Remove the case from the phone. It is the only way to also clean the inside and the edges — where dust accumulates and can, over time, micro-scratch the phone's chassis.
- 2. Wipe with a slightly damp microfiber cloth over all surfaces. In 90% of cases, that is enough.
- 3. For stubborn marks (grease, makeup, pocket marks): a drop of mild soap such as dish soap diluted in lukewarm water, applied with the microfiber, then a pass with clear water.
- 4. Dry with a clean cloth before putting the case back on — never reassemble damp, as moisture trapped between case and phone is to be avoided.
Recommended frequency: a full clean once a month, and a microfiber wipe whenever the surface needs it.
Products to never use
Carbon fiber is nearly indestructible — but the resin that covers it, like any technical varnish, has its enemies:
| Product | Risk for the case |
|---|---|
| Acetone, solvents | Chemical attack on the resin: irreversible dulling |
| Pure alcohol | Dulls the finish with repeated use |
| Bleach and harsh detergents | Discoloration, surface alteration |
| Abrasive sponges, scouring powders | Visible micro-scratches, especially on glossy finishes |
| Steam cleaner, very hot water | Unnecessary thermal stress on the resin |
In short: nothing stronger than soapy water. If a product stings the nose or strips paint, it has no business on your case.
Special cases depending on your accessories
- Apple Watch case: exposed to sweat during sport — a rinse with clear water after big sessions is enough, the non-porous surface does not retain odors. See the Apple Watch Carbon collection.
- AirPods or Galaxy Buds case: it lives at the bottom of pockets — remember to dust the inside of the AirPods case so lint does not migrate to the charging port.
- License plate frame: exposed to the road, it gets cleaned along with the vehicle — classic car shampoo, never abrasive polish. See our carbon accessories.
- Money clip: a simple microfiber wipe — daily contact with hands even gives it a slight satin sheen over time.
FIBRE, FORGE, BRUTE: slightly different care?
The three finishes are cleaned the same way, with two nuances:
- The FIBRE finish and FORGE, being smooth, only need the microfiber move.
- The BRUTE finish, textured, can hold a little more dust in its relief: press slightly with the damp microfiber, or use a very soft-bristled brush (makeup-brush type) dry.
- The colored versions are cared for exactly like the black ones: since the pigments are fused into the resin and not applied to the surface, there is no color layer to preserve.
What care cannot do
Let's be honest: cleaning does not repair a deep scratch from a fall on gravel, and does not fill a chip on a corner after a violent impact — the case then did its job: taking the hit instead of the phone, as our article on carbon's real protection explains. The good news: unlike cracked plastic, a marked carbon case remains structurally sound and keeps protecting.
Conclusion: 5 minutes a month, years of good looks
A microfiber cloth, soapy water, zero solvents: that is all carbon asks to go through the years without losing its depth. It is this care-to-lifespan ratio that makes a carbon case a purchase you don't redo every six months — explore the three finishes in our full collection, for iPhone as for Samsung Galaxy.
FAQ — caring for a carbon case
Can I run my case under water?
Yes, a rinse with lukewarm water is no problem: epoxy resin is waterproof. Simply dry the case before putting it back on the phone.
How do I disinfect my case without damaging it?
Soapy water eliminates most bacteria. If you insist on disinfecting, a wipe lightly soaked in 70% isopropyl alcohol used occasionally is tolerable — but not daily, which would eventually dull the finish.
Can my carbon case yellow like a clear case?
No. Yellowing is a chemical reaction specific to silicone and TPU exposed to UV. Epoxy resin loaded with carbon fibers is stable: no yellowing, no discoloration.
Does the BRUTE finish hold dirt?
Its relief can catch a little more dust than a smooth surface, but nothing a damp microfiber or a soft brush doesn't fix in seconds. It is the — modest — price of its unique material feel.
Do the colored versions require special care?
None: the color is in the resin's mass, not on the surface. It does not chip, does not fade, and cleans exactly like a black finish.
How often should I clean the inside of the case?
Once a month: the dust that slips in is the leading cause of micro-scratches on the phone's back — ironically caused by the case meant to protect it. Five minutes of removal-and-cleaning prevents it.
