Why Did the Car Cover Turn Blue?

It is clearly due to color fading. Here is some relevant information about car covers: 1. Features: High-quality car covers are made of high-density flame-retardant fabric; they have excellent waterproofing effects; car covers have flame-retardant functions, meaning they do not catch fire easily. Unlike ordinary car covers that can easily ignite when exposed to sparks, posing significant hazards, this flame-retardant car cover does not catch fire, and the exposed area does not burn or spread, ensuring great safety; additionally, the material of the car cover is soft and will not scratch the car paint. 2. Product Functions: With a car cover, you can effectively protect your car from harmful dust settling in the cabin and engine parts, preventing aging of the cabin interior and wear on the engine; it can effectively avoid the erosion of acidic rain and snow in urban pollution conditions on the car's surface; it can effectively resist strong UV rays that damage the car paint, interior, and tires.
I've also encountered the issue of car covers turning blue before, and after some research, I realized it's mainly caused by oxidation reactions. When car covers are exposed outdoors for extended periods, enduring wind, sun, and rain, the protective coating on the surface gradually degrades. UV rays are particularly damaging, causing the plastic molecules in the car cover material to break down. Combined with high temperatures, which intensify molecular activity, yellowing becomes more likely. Gray car covers will first turn yellow with age, then gradually fade to a light blue, much like how plastic buckets become brittle and blue over time. This level of aging directly reflects the lifespan of the car cover, and the discolored areas will also feel more brittle and hard to the touch. I recommend choosing car covers with UV-resistant coatings, parking in shaded areas whenever possible, and using specialized car cover cleaners for maintenance every three months to effectively slow down the discoloration process.
The issue of car covers turning blue is truly frustrating, primarily caused by material oxidation. My car cover started showing this discoloration after just two years of use, particularly becoming noticeably bluish after prolonged sun exposure. Later I learned that the plastic surface layer of car covers undergoes degradation under UV radiation, damaging its internal chemical structure - the original hydrocarbons decompose into oxygen-containing compounds. It's similar to how plastic bottles become brittle and bluish after long-term sun exposure. Rainy weather accelerates this process as airborne pollutants mix with rainwater and adhere to the cover, creating micro-corrosion points. Lower-quality covers made with cheap recycled plastics turn blue even faster. I've developed the habit of checking parking environments carefully now, consciously avoiding areas near air conditioner exhaust vents or trees with heavy sap. I also wipe down the surface with a damp cloth every six months to remove accumulated dirt.
