Why Does Car Trim Fade? (And What You Can Do About It)

Have you noticed your once-black plastic trim turning dull, gray, or chalky? You’re not alone. Car trim fading is one of the most common (and most frustrating) issues car owners face. But why does it happen — and more importantly, how do you fix it?

The Real Reason Car Trim Fades

Your plastic and rubber trims are constantly exposed to harsh environmental conditions. Over time, these cause oxidation — a chemical breakdown that strips away the deep black pigment and leaves behind a dull, faded appearance.

• UV radiation: The #1 cause of fading. Sunlight breaks down plastic polymers and dries out surfaces.
• Water and road salt: Wash away protective oils and accelerate wear.
• Harsh cleaners: Degreasers and detergents can strip plastic of moisture and finish.
• Friction and weather: Snow brushes, dirt, rain — it all adds up.

How to Tell If Your Trim Is Damaged

• The surface feels dry or rough to the touch
• The color looks gray or cloudy
• It no longer repels water
• There’s uneven shine or spotting

How to Reverse the Damage

Thankfully, faded trim doesn’t mean it’s ruined forever. Here’s how to bring it back:

1. Clean the surface: Use a plastic-safe cleaner to remove dirt and residue.
2. Apply a trim restorer: Choose a high-quality product like Carfidant Plastic Restorer designed for UV protection and color restoration.
3. Let it absorb: Allow the formula to penetrate the surface for long-lasting results.
4. Buff excess: Use a microfiber towel to smooth and even out the finish.

How to Prevent It From Happening Again

Once restored, protect your trim with these habits:

• Reapply your restorer every 6–8 weeks
• Use pH-neutral car wash soaps
• Park in the shade when possible
• Dry trim thoroughly after rain or washing
