Seeing water spots on your freshly washed car? Timing your wash makes the difference between a sparkling finish and frustrating streaks.
The ideal car washing time is early morning or late afternoon on cloudy days. Cool temperatures prevent rapid drying that causes water marks.
Professional detailers schedule washes when temperatures stay between 50-80°F (10-27°C) - avoiding direct sunlight and extreme weather conditions.
Is it better to wash your car in the morning or at night?
Choosing between dawn and dusk for washing involves understanding how temperature and sunlight impact your results.
Morning washing beats evening washing because:
- Lower water evaporation rates
- More daylight drying time
- Cooler surface temperatures
- Less evening dew risk
Best Practices:
- Wash (6-10 AM) > Dry (before noon)
- Garage storage afterward
- Avoid washing after dark
- Check weather forecasts
Exception: Night washing works if drying thoroughly indoors afterward.
