Ideally, wash when temperatures range between 70-80 degrees Fahrenheit. Of course, summer often brings weeks-long stretches of heat, so finding a cool day to wash may be easier said than done. In that case, plan to wash in the early morning.

You may want to avoid washing your car if the outside temperature is at or below freezing (32 degrees Fahrenheit). Shoot for doing a car wash in cold temperatures when the thermometer shows a reading of at least 49 degrees. Ideally, though, the temperature should be between 50 and 89 degrees.

Keeping your ride clean helps keep it in good condition. If the weather's not too harsh where you live, washing your vehicle every two weeks is a good rule of thumb to help your car last longer. However, if you apply a coat of wax at the end of each cleaning session, you may be able to wash it less often.

In general, it is recommended to wash your car every two weeks to maintain its appearance and protect the paintwork. However, if you live in an area where there is heavy pollution, road salt, or bird droppings, more frequent washing may be necessary.
