Soak the entire vehicle with a low-pressure stream of water (using a hosepipe or merely splashing with a tumbler - to remove the loose dirt particles on the surface)and then wipe it using a soft damp cloth or sponge. Wiping the car straight away can cause dirt particles to embed and stratch the paint.

Using special car-wash soaps help removal of dirt. Normal detergents can be harsh on the cars wax finish.

Start at the top and work down to the lower areas of your car to avoid risk of picking up dirt particle or tar pieces below and dragging them over your car's upper, high profile paint finish.

The lower body panels and the underside of your car are most prone to collect stubborn roadway contaminants, and are the areas that require the maximum cleaning attention.

Dry your car using synthetic chamois (a leatherlike cloth). A chamois is smoother than normal cloth (which can accumulate small dirt particles) and is effective for the final wipe down of your car. Remember to dry your vehicle from top to bottom.
