How often do you wash your car?
Daily? Weekly? Monthly? Based on need?
Maybe this belongs in the detailing forum, but it's really not a detailing question so much as an ownership question.
I foam mine up almost every other morning before the sun crosses our barn (with the pressure washer foam attachment) and then a quick blast to rinse - wheels, wheelwells and body of the car. Open the hood and trunk to dry and then if time a quick run-over the flat surfaces with detail spray.
Is that excessive?
