Car Wash Claims Brushes "Can't scratch your vehicle"

[dlc95]

What if the vehicle right before you happened to be this?

I'd bet there's going to be a considerable amount of mudd and grit left on those fancy Tommy or Hanna brushes, enough to wind up causing scratches & swirls once they begin washing your vehicle... I mean that's like trusting the brush, even if it's made of boars hair at the local coin op. Of course a well maintained boars hair brush on it's own won't scratch your paint, it's the likely condition it's in that's the culprit.

I'd get this at my wash. I had to power wash my brushes, and run the wet down system before letting other cars follow.

Back in the 90's though, at Rochester Auto Wash, cars that looked like this were par for the course.

And yeah, that's not going to come totally clean at a "production tunnel wash". And because it's usually over a million dollars to build new, all conveyor tunnel washes are "production"

The car wash I worked at had two guys, one on either side of the car with power washers that "washed" the cars prior to them entering the tunnel. Cars like this were charged extra because of the amount of time it took to get all the mud off before going into the (of course) plastic/nylon brushes that scratched the hell out of the cars. The tops of the cars didn't get swirled so bad because we had hanging "chamois" strip curtains that were heavily soaped and waved front to back along the tops of the cars.
