Cleaning plastic chrome trim requires a gentle approach to avoid scratching or damaging the finish. Here's a step-by-step guide:
Preparation is Key
-
Wash and Dry: Begin by washing the car, or at least the area around the trim, to remove loose dirt and debris. Thoroughly dry the surface before proceeding. (Reference: First step is to wash and dry the car, or at least the area you will be working on. Then use the Clean Detail spray to give a further clean of the chromed surface. Spray it quite liberally onto the chrome and then wipe it away with the higher pile/plush side of the Big Softie microfibre cloth.)
-
Choose Your Cleaning Solution: Several products work well, including dedicated chrome cleaners, all-in-one detailing sprays (like Klasse AIO), or even mild soap and water. Avoid harsh chemicals or abrasive cleaners. (Reference: Not only is Klasse AIO great for cleaning / polishing / protecting these chromed plastic parts, but it's also a tremendous product for painted…)
Cleaning Process
-
Apply the Cleaner: Liberally apply your chosen cleaner to the plastic chrome trim.
-
Gentle Scrubbing: Use a soft microfiber cloth or sponge to gently scrub the trim. Avoid excessive pressure to prevent scratching.
-
Rinse and Dry: Thoroughly rinse the trim with water, ensuring all cleaning solution is removed. Dry the trim immediately with a clean, dry microfiber cloth. (Reference: Use a hose or a bucket of warm water to thoroughly rinse the trim, ensuring all loose particles are washed away.)
Dealing with Oxidation and Corrosion
For heavily oxidized or corroded trim, more aggressive cleaning may be necessary. This might involve using a dedicated plastic chrome cleaner, a polishing compound (used with caution), or even more intensive methods like those shown in videos demonstrating the restoration of heavily degraded trim. (Reference: How To Remove Corrosion & Oxidation on PLASTIC CHROME…) If the damage is significant, replacement may be necessary. (Reference: Did the toothpaste not sort out those cavities? As you can see quite clearly from your own photographs, the "chrome" has degraded. There is…)
Tips for Success
- Microfiber cloths: Always use soft, high-quality microfiber cloths to avoid scratching.
- Test in an inconspicuous area: Before applying any cleaner to the entire trim, test it on a small, hidden area first to ensure it doesn't damage the finish.
- Regular cleaning: Regular cleaning helps prevent the buildup of dirt and grime, making future cleanings easier.
