No, it is generally not recommended to wash your car in direct sunlight.
Here's why:
- Water Spotting: The sun's heat causes water to evaporate quickly. Before you have a chance to dry the car, minerals in the water can leave unsightly spots and streaks on the paint. This is especially true if you have hard water.
- Soap Residue: Soap can dry prematurely in the sun, leaving a film or residue that's difficult to remove and can also cause spotting.
- Heat Damage: The sun heats up the car's surface, which can cause the soap to dry even faster and potentially damage the paint or clear coat in extreme cases.
Instead of washing your car in direct sunlight, consider these alternatives:
- Wash in the Shade: Find a shady spot, like under a tree or in a covered area.
- Wash Early Morning or Late Afternoon: These times of day are typically cooler, reducing the risk of water spots and soap residue.
- Use a Quick Detailer: If you have to wash in the sun, work in small sections and immediately dry each section with a microfiber towel. A quick detailer spray can help prevent water spots.
In conclusion, washing your car in the sun can lead to water spots and soap residue, damaging the paint and clear coat; washing in shade or early morning/late afternoon is recommended.
