How to Properly Care for Your Carbon Fiber Parts
Published: August 26, 2025
Carbon fiber is not only performance-driven, it is also one of the most striking visual upgrades you can add to your BMW. From mirror caps to front lips, diffusers to interior trim, carbon fiber elevates your build with motorsport pedigree and aggressive styling. But with great looks comes responsibility: carbon fiber needs the right care to stay glossy, strong, and free from yellowing or fading.
At RMD Performance, we ship carbon fiber aero and interior parts across the U.S., and one of the most common questions we get is: How do I take care of my carbon fiber?
Here’s your complete guide.
1. Understand Carbon Fiber Finishes
Most aftermarket BMW carbon fiber parts are finished with a UV-protected clear coat. This keeps the weave glossy and prevents sun damage. However, cheaper parts or older pieces may not have strong UV resistance. This makes them more prone to fading or yellowing if not cared for.
-
Gloss Finish: Sleek and reflective, but shows scratches more easily.
-
Matte/Satin Finish: Subtle and aggressive, but fingerprints and oils can show.
Knowing your finish helps determine the best cleaning method.
2. Cleaning: Less Is More
Carbon fiber does not need heavy chemicals. In fact, harsh cleaners can damage the clear coat. Stick to simple, gentle methods:
-
Rinse First: Use clean water to remove dust and dirt before wiping.
-
Use pH-Balanced Car Shampoo: The same soap you use for your paint works perfectly.
-
Microfiber Towels Only: Never use rough cloths or sponges that can scratch the surface.
Pro Tip: For interior carbon fiber trim, use a damp microfiber with a little interior cleaner. Never soak it.
3. Protect Against UV Damage
Sun exposure is the biggest enemy of carbon fiber. Even with UV clear coat, years of sunlight can dull the finish.
-
Wax or Sealant: Apply a wax or ceramic sealant designed for carbon fiber or paint surfaces every few months.
-
Ceramic Coating: For long-term protection, ceramic coating locks in gloss and shields against UV, water spots, and minor scratches.
-
Garage or Shade: When possible, avoid long-term direct sun exposure.
4. Avoid Harsh Chemicals
Stay away from:
-
Strong degreasers
-
Abrasive polishes not made for clear coat
-
Household cleaners like Windex, bleach, or ammonia-based sprays
Stick to automotive-safe cleaners only.
5. Fixing Minor Damage
If your carbon fiber develops light scratches or swirls:
-
Gloss Finish: A light polish with a clear coat safe compound can restore clarity.
-
Matte Finish: Do not polish, it will create shiny spots. Instead, use a matte-specific protectant.
For cracks or peeling clear coat, it is best to consult a professional. Attempting DIY fixes can make it worse.
6. Long-Term Care Routine
Here is a simple upkeep routine:
-
Weekly: Rinse or wash with car shampoo.
-
Monthly: Apply spray sealant or wax.
-
Yearly: Consider ceramic coating or reapplication if already coated.
Consistency is key. Just like your paint, carbon fiber looks better and lasts longer with regular care.
