Personally, I use Meguiars gold class wash, in a Mr. Clean spotless car wash sprayer. Diluted Simple Green on the wheels. Always handwash, in the shade, never in the sun. Blow dry with a Toro electric leaf blower, then a clean microfiber towel to finish the drying.
Wax with Meguiars NXT or Rejex. Rejex is what I use on my airplanes. Lasts a long time in harsh environment, not quite as shiny.
Once a year or so, clean, wash, claybar the entire exterior.
Tar, bugs, other poop, clean with a liquid type bug and tar remover promptly.
The car paint will look like new for many years. Keep it out of machine washes, use the gentlest thing possible to clean it.
Interior, just use a damp cloth to clean the vinyls and plastics. Lexol cleaner works on leather. A little goes a long way, just follow the instructions. Vacuum regularly. Floor mats will come very clean in the washing machine, dry and respray with Scotchguard. Mr. Clean magic erasers are really good on stubborn scuff marks.
I got this down to a science.
