Have you noticed that the exterior plastics on your car no longer look black, but rather gray, dull, or even ashy? You're not alone. This problem is more common than you think, and we often cause it without realizing it.
Here are 5 things that harm them and how to avoid them:
1. ☀️ Prolonged exposure to the sun
The number one enemy of plastics: UV rays. When you leave your car in the sun for hours (or worse, every day), the plastic gets sunburned, loses natural oils, and begins to deteriorate. The result: dry, gray, and cracked surfaces.
✅ Solution: Use a plastic restorer with UV protection, like the ones we have at SupremoClean. And if possible, park in the shade or use a sunshade.
2. 🧼 Using products not designed for cars
Many people use bleach, laundry detergent, or dish soap to wash their cars, and this damages the finish of the plastics. These are harsh products that dry out the surface and strip the color.
✅ Solution: Always use neutral car shampoo and products specifically designed for plastics. Your car isn't a frying pan.
3. 🌫️ Environmental pollution and acid rain
Air pollutants, dust, acid rain, and even constant humidity form a layer that slowly "burns" the plastic, leaving it opaque over time.
✅ Solution: Maintain a regular cleaning routine and apply sealants or protectants. This creates a barrier that prevents contaminants from adhering.
4. 🧽 Abrasion or improper washing
Scrubbing it with stiff fibers, unsuitable brushes, or old sponges creates micro-scratches and wear. Over time, the surface loses its shine and looks aged.
✅ Solution: Always use microfiber cloths after a good pre-wash and apply the appropriate product. The small details make all the difference.
5. ⌛ Lack of maintenance
Leaving months without applying conditioners or protectants causes the plastic to dry out naturally. All materials need maintenance. Yes, plastic too.
✅ Solution: Apply a durable polymer-based restorative every 3 to 4 weeks. Your pet will thank you for it.
In short: Car plastics don't magically disappear. They deteriorate over time and with bad habits. But with good products and regular maintenance, you can restore their color and shine to like-new condition.
