The best and cheapest option for
washing at home is a simple
two bucket system with a grit guard as this is where almost all people go wrong with washing themselves having no idea that only using one bucket along with sponges and chamois is what is scratching their cars paint.

One "wash" bucket for your shampoo (must be a PH neutral product) and a separate "rinse" bucket with a grit guard and washboard.
Using a
microfibre wash mit only to wash the car,
before dunking it in the "wash" bucket first scrub it out in the water only "rinse" bucket with the grit guard/washboard to remove and dirt from the mit so you only ever contact the car with a clean mit ensuring you dont create fine swirl scratches from a dirty mit. Also use separate mits for paint first and wheels last and regularly put the mits in the washing machine using a microfibre washing liquid.
Also avoid drying with a chamois as they, like sponges hold and rub dirt into the paint so a large microfibre drying towel is the way to go and take the gun off the end of your hose and let the water run freely when rinsing down the car avoiding high pressure contact or use it in showerhead mode.
So yes contactless washing is great but not a realistic option for many so if you need to contact the car just make sure its ALWAYS with a CLEAN microfibe product and nothing else.
And a great two stage ceramic coating does make cleaning easier and can last beyond 5 years with simple maintenance. I used the latest product from Gyeon out of Korea:
GYEON quartz
