Does anyone know of a good manual spray car wash in the NYC, Bergen, Rockland area? I'm looking for a place where I can spray the hell out of my car/undercarriage during the winter to prevent salt and sand buildup.

I think they are all automatic. If you go to the Rainbow CW on Franklin Turnpike in Mahwah, NJ they do a good under body wash. Otherwise if you come up to Fishkill, NY there is a good manual one near the 'Cracker Barrel' on Route 9. Take the Thruway up to Newburgh and then 84 West to Rt 9 (exit 13)

There are also good manual CWs in Monmouth County, NJ

If anyone knows where the Palisades mall is in West Nyack, there is a nice manual car wash right across from it on Rt. 59. Get that salt off your car.
