I wash my Mercedes, I then use a clay bar/mitt on the paintwork. I then use a good quality wax (in my case Dodo Juice Diamond White). If I can be bothered I Hoover the inside and treat the dash etc. with a something to make it looks and smell nice. I wash it, clean it, valet it. I never 'detail' it. Grumpy old man rant over! Happy belated new glass half full year!
