Are you talking about just vacuuming the interior or steaming cleaning the interior. If your just vacuuming and armor all the interior shouldnt take you no more then 20 mins each for the inside of the truck.
We call this a refresh.... includes vacuum, windows, armor all, smell good amd wash with spot free water. Takes us around 25-30 to complete and we charge $65.00
If the interior needs to be steamed cleaned we charge $55.00 more and only adds about 15 mins to the time.
