Fill two buckets with water
Place grit guard( if any :P)
Add car soap to one bucket and let the other bucket stay with water only
Rinse down your car
Give a burst from the hose to the shampoo bucket to make suds.
Dip your washmitt in the shampoo solution and soak it well.
Wipe one panel gently in one direction
Work from top to down
After completing one panel go back to your plain water bucket and rub the washmitt inside the water against the grit guard or in my case- bare hands like you wash your hands with soap:P
Squeeze out the water
Dip in shampoo again and continue washing your car
Always go back to your rinse bucket before loading with shampoo
Do this quickly and do not let the shampoo dry
Rinse off the shampoo and check if there is water beading.
Dry the car top-down
Give a detailer wipe or even better, wax it:D
