Hi,
Here's my washing procedure, and i apologise if it's obvious:
1. The car should be cold, i.e. never wash it if you have just been for a drive. The bonnet will hot. Park the car in the shade. Never ever wash a car in direct sunlight. If no shade is available either wake up early or wash it late when the sun is weak and not directly on the car.
2. Thoroughly rinse the car with water from the hose to get rid of any loose grit, dust etc.
3. Get your car shampoo nice and sudsy.
4. Sponge one side of the car. Rinse off with water before starting the other side. This ensures the suds dont dry on the paintwork and start to stain/mark.
5. Sponge the other side, again rinse off when finished.
6. Give the whole car a quick rinse again from the hose, the idea being that the paintwork should not dry out before you dry it.
7. Clean the wheels and sills with a separate sponge.
8. I use a "Meguiar's soft buff synthetic chamois". Where possible i open the chamois to full size and lay it flat on the car (such as with the bonnet). I hold two corners and pull it across the car. This always removes most the water. I wring out the chamois very frequently.
9. I then use a micro-fibre cloth to dry the wheels and sills.
10. Open the doors, bonnet, boot lid and petrol cap (and pop up headlights if it's an NA) and wipe down any water present in these areas again with a micro-fibre cloth.
11. Once the car is dry, i keep checking and removing any drips of water that keep running down from the door mirrors onto the door.
When i bought my chamois it states on the plastic tube container that it needs to be used a few times before it performs at its best.
Also when i have finished with the chamois i wring it out so it's damp and put it back in its plastic tube. This way it never dries out and is ready for the next time. I often check my chamois before washing the car to see if it has picked up any grit, obviously that would not be good.
Cheers
