I use a chenile mitt, meguires gold class premium car wash (or a high quality gel type wash with sheeting action), and dry it with a water sprite (simulated chamois - this thing is amazing how much water it holds). I dont really wax it often, either. Sometimes only once a year.
About 80% of my Black paint is 17 years old (both sides of my truck are original paint). This is pretty much how it has been treated since I bought it in 1991.
