Pressure washer with a foam canon. Ladder for the roof, porter cable for the polish. Spray wax to touch up, I live on a dirt road so I am not as anal about keeping my vehicles spotless but I do like them looking nice. Spray wax with hydrophobic properties have gone a long way, give those a try.

Helps with maintenance cleanings. Use a leaf blower to help with the drying process

Full detail twice a year.
