It may be tempting to wash your car in the blazing afternoon sun, but that’s literally the worst time. When it comes to washing cars, the sun isn’t your friend. Even if you have the best tools and high-end soap, we’re willing to bet that you’ll still be left with streaking and residue. You’ll have the sun to thank for that.
What’s the fix? Opt to wash your car on a cloudy day or in the early morning before the sun gets too strong. The heat from the sun causes the soap to dry on your car before you can rinse it off completely which will leave you with a milky looking residue and spots. Switching to an overcast day or a time when the sun isn’t as strong will yield exponentially better results
