The best way to clean and restore faded plastic car trim is a simple two-step process: first, a thorough cleaning with a dedicated plastic cleaner or an all-purpose cleaner diluted with water, followed by the application of a UV-protectant trim restorer. This method effectively removes grime and replenishes the oils and protectants that sun and weather strip away, preventing the plastic from turning gray and brittle.
Faded plastic trim, often seen on bumpers and wheel arches, is caused by oxidization from prolonged exposure to UV rays. Simply washing it isn't enough; you need to remove the oxidized layer.
Step 1: Deep Cleaning
Start with a clean surface. Use a dedicated interior & exterior plastic cleaner or a diluted all-purpose cleaner. Spray it onto a soft-bristled brush or microfiber cloth and scrub the trim thoroughly. A brush helps get into the textured grain. For stubborn stains, a magic eraser (melamine foam) can be effective, but use it sparingly as it's slightly abrasive. Rinse completely with water.
Step 2: Restoring and Protecting
After the trim is completely dry, apply a trim restorer. These products are formulated with oils and UV inhibitors to rejuvenate the plastic. Armor All and Meguiar's are common consumer brands, while professional-grade products like CarPro PERL offer longer-lasting results. Apply with an applicator pad, let it sit for a few minutes, then buff off any excess with a clean microfiber towel. The key is consistency; reapplication every few months is necessary for lasting protection.

Avoid using tire shine products on trim, as they are often too oily and can cause streaks on adjacent paint. For long-term gray trim restoration, testing a heat gun is a popular method, but it's risky as it can permanently damage the plastic if overheated.
