Have you ever spent a Saturday morning meticulously washing your car, only to be left with streaks and water spots baked on by the afternoon sun? It’s a frustrating experience, and it begs the question: should you wash your car in the sun?
Let’s dive in and explore the answer, along with some car washing wisdom to keep your ride looking its best.
The Science Behind the Spots
From a car enthusiast’s perspective, washing your car in direct sunlight is a bit of a detailing faux pas. But why? The answer lies in simple science:
- Evaporation: Water and soap dry faster in the sun, leaving behind mineral deposits that show up as unsightly spots.
- Heat: A hot car surface can cause car wash solutions to dry even faster, exacerbating the water spot issue.
“Think of it like this,” says renowned automotive detailing expert, Dr. James O’Connell, author of “The Immaculate Finish: A Guide to Car Detailing Perfection,” “leaving a wet car to dry in the sun is akin to leaving dishes to air dry—you’re bound to get spots.”
The Case Against Washing in the Sun
Beyond the science, consider these real-world scenarios:
- Imagine: You’re washing your sleek, black Mercedes-Benz C-Class on a sunny California afternoon. The sun beats down as you work, and despite your best efforts, those dreaded water spots start to appear.
- Or perhaps: You’re detailing your classic Ford Mustang in your driveway in sunny Florida. You’ve just finished washing when your neighbor pops by for a chat. By the time they leave, the sun has done its damage, leaving your hard work covered in spots.
Frustrating, right?
What Can You Do?
- Seek Shade: If possible, wash your car in a shaded area or during a cooler part of the day.
- Work in Sections: Wash and dry your car in small sections to prevent water and soap from drying on the surface.
- Use a Quick Detailer: A quick detailer can help remove water spots after washing.
- Consider a Water Softener: If you live in an area with hard water, consider using a water softener or deionized water for your final rinse. This minimizes the mineral content that contributes to water spots.

Is it better to wash your car in the morning or evening?
Both mornings and evenings offer cooler temperatures and often less direct sunlight, making them ideal times for car washing.
