Caring for and sealing carbon: Protection against yellowing & UV

Properly caring for and sealing carbon: Protection against yellowing and UV damage

Real carbon fiber is a real eye-catcher – but only as long as the surface is well-maintained. Sunlight, the wrong cleaners, and neglect will eventually lead to dull spots, yellowing, or micro-scratches. In this guide, you'll learn how to properly clean your carbon parts, seal them permanently, and keep them looking like new for years to come.

Why does carbon yellow or fade at all?

Visible carbon fiber is made of carbon fiber fabric sealed with a clear coat. This clear coat, not the fiber itself, is the part that ages. The main cause is UV radiation, which attacks the coating, causing it to yellow and become dull. In addition, aggressive cleaners, insect remains, bird droppings, and micro-scratches from improper wiping contribute to the aging process. Those who are aware of these factors can take specific preventive measures.

How to properly clean carbon – step by step

1. Rinse roughly Rinse off dust and dirt with water so nothing gets scratched.
2. Gentle wash Clean with pH-neutral car shampoo and a soft microfiber cloth or sponge.
3. Persistent solving Gently soak insect remains instead of rubbing them off.
4. Drying: Dab with a clean microfiber cloth, do not scrub the surface.

Seal carbon – this is how the shine is maintained

Cleaning alone does not protect against UV. The seal provides the actual protection. There are several levels depending on the requirements:

A new clear coat seal is the most sustainable solution for heavily used or already dull parts. You can find suitable materials and accessories in DIY Shop. Anyone who wants to have an original part completely refurbished will find our Carbon finishing best advice - the surface will be resealed and shine with full splendor again.

Interior vs. Exterior Parts Care

Interior parts like decorative trim or center consoles are barely exposed to UV radiation – regular, gentle dusting is sufficient here. Exterior parts like mirror caps or add-on parts, on the other hand, are constantly in the sun and require robust UV protection as well as more frequent care. If you are planning new exterior parts, a high-quality sealant is worthwhile from the very beginning.

What to do about dull spots or scratches?

If the seal is already damaged, care alone will no longer help. Superficial scratches and dull spots can be rectified by sanding and re-sealing – read the detailed guide on how to do this. „Repairing carbon parts“. For larger damages, our team will handle the processing through the Carbon Repair.

Care begins at purchase

How easy a part is to care for also depends on the quality of the original seal. High-quality finished visible carbon parts – such as our Carbon-reinforced plastic parts – are well protected from the factory.
