True enough... but... I have some additional "insider" information some members may want to consider before letting car wash brushes near their cars.
First... it depends on the car wash company itself. The scratch free brushes are more expensive than others. Car wash owners have choices when it comes to heir supplies and how much they want to spend. Like most products, material choices effect the price. Brushes bristles can be made of boars hair, foam, and plastic to name a few. The scratch free brushes are usually advertised as being made of extra-fine polystyrene with flagged tips. Plastic bristles "will" scratch" a clear coat every time. It pays to know if the owner of the car wash runs a quality operation... or is just out to make money. That said, most car washes have a 1-800 number posted that you can call to report problems, request refunds etc. Call the number and ask if they can tell you about the brushes... ( i.e. are they scratch free etc). If they don't know or avoid the question... find another car wash. Some car washes will actually advertise the fact they use quality brushes on their website or billboards (e.g. "All Speedy Car Wash locations feature soft foam rubber brushes do not scratch or cause damages while giving your vehicle the best wash possible.)
Second... it also depends on which brushes we are talking about... the hand held foaming brush or the motorized brushes in the drive thru car wash. For the most part the hand held foaming brushes are safe to use "IF" you have inspected them first and determined the bristles are of the scratch free variety and you give the brush it a good cleaning before using it, by spraying it down with the high pressure soap wand to blast out any dirt and/or debris left in it by the last customer who used the brush to remove the dirt and mud from his off road 4-Wheeler... or clean the Barbecue grill in the back of his pickup. I generally lay the brush on the ground, bristles up, and with one foot on the handle to keep it from moving, blast the heck out of it with the high pressure soap before I let it any where near my car.
However, if we are talking about the drive thru car washes with revolving brushes... I wouldn't let them within 10 feet of my Rogue... unless... I saw the 2 or 3 cars in line ahead of me and verified they hand minimal surface grime. Why? ... Well, between my bother and brother-in-law they own 16 self serve car washes. Each car wash has at least one "touchless" drive thru bay (i.e. a series of high pressure wands that revolve around your stationary vehicle, as well as spray the wheels and undercarriage). Before they converted to the "touchless" bays, they had the top dollar mega expensive swirling brushes that were as soft as rabbit fur and guaranteed not to scratch. The brushes were cost a couple grand each due to their size and the properties of the scratch free material. However after numerous lawsuits by unhappy customers with scratched or swirled clear coats... they converted all their car washes over to touchless. During the lawsuits the manufacturer stood behind their brushes as scratch free. The problem was the investigation of the scratched cars showed it wasn't the brushes... but dirt trapped in the brushes from the car that went thru ahead of the scratched cars. My brother added longer rinse times to the brushes between car washes in an effort to clear out any dirt but the problem still occurred. If a car was super dirty (i.e. mud covered)... nothing short of a concentrated effort of individually washing and rinsing each brush could guarantee they were free of dirt. As a result... they cut their losses... pulled all the brushes and converted all brush bays over to touchless.
NET: If you're going to drive thru a swirling brush car wash... and you didn't see the vehicle that went thru just before you... then cross your fingers and pray it wasn't Bubba in his pickup after a hard weekend of 4 wheeling.
