One of the neighbors with a huge truck that has never seen a load in the bed has it (and his other 3 cars) detailed every friggin week.

The detailer runs a generator and a compressor and a pressure washer - all obnoxiously loud for hours at a time. Then uses a god damned leaf blower to dry it. FFS. Just use a towel. Jeeze.

And this is CA. No need to wash your cars this often. Waste of time, money, water, and fossil fuels
