Make sure that you never dry dust the car under any circumstances.
Lubricate the dirt and grime off the surface using a wax safe, pH neutral shampoo. Only use the two bucket method to wash your car and use the correct tools for detailing. Only use microfiber cloths and good quality wash mitts that are cleaned after each use.
If youre in the mood of a durable wax, shampoo, tire gel, cloths and applicators in one decent package, i suggest you buy a meguiars new car kit. It has everything you need to start your detailing hobby.
