Came across a car wash product called “ONR”, recommended to me by one of my employees who’s husband does detailing. Can get through Amazon or car professional channels. Mix it 1oz to a bucket of water, can give the car a no-rinse sponge bath, or 1oz to a spray bottle of distilled water makes a good spot free interior and exterior detail spray. In my case it’s too hot outside to wash the car right now without water spots drying so I can do a quick maintenance wash in the garage without making a mess. For those of you with water restrictions you could do a weekly wash with just a couple gallons. I was skeptical of an “everything” product but I upgraded to a car worth keeping shiny and it’s been working.
