The Cool Way to Wash Your Car

If your car has been sitting in the sun or you’ve just taken it for a long drive, you should wait until it cools down before soaping up. Park it in the shade for a couple of hours—or start with the interior. A hot exterior speeds the drying of the soap and water. While that may sound like a good thing, it makes washing more difficult because it increases the chance of spots and soap scum. Avoid the hassle—wait until things cool off before soaping it up!
