I referred my father to Christian Clean, and he was happy with the result. My father is pretty rough on cars--spilling coffee, constantly leaving the windows down, but Christian Clean did a faulous job of cleaning the car at a very resonable price. Christian Clean offers a number of cleaning services for the very basic, to complete detailing bumper to bumper and under the hood.
I like that this is a Christian based company. You will be hard-pressed to find a more dedicated, hard-working company.
PROS: price, service
