I know not to wash one in the sun or when the car is hot. So how long do you guys wait to wash it? What do you professionals do when one is hot? I am planning to clean my mother-in-laws Enclave this coming week with her cleaning stuff she got with the Enclave. She will come to my house late mourning about 1 hr away. I am going to pop the hood up and use a box fan to help cool the motor and clean the inside. Does anyone know how tall they are,not sure if it will fit in my garage. thanks
