I have a gantry type automatic carwash with onboard dryers. I am thinking of removing the dryers from the machine and moving them outside the bay. I don't think the onboard dryers are a good idea. It seems you get triple foam and soap residue being blown off the machine and onto the vehicle when the car is drying and what ever else is laying on the floor as the machine moves across the vehicle. Does anyone else experience these issues with onboard dryers? Is there any drawbacks to moving the dryers outside the bay?
