So this is an old wives tale.
Even if it were true, you would be spraying off super chunky salty surface conditions and replacing them with much more dilute salty surface conditions. This seems like an improvement to me.
And virtually nobody claims that excessive car wash underbody spray usage has ever resulted in accelerated underbody rust conditions.
So there's that...
Car washes here are required to reuse water. Not an old wives' tale at all, but a fact of many car washes.
If I had a choice between chunky surface salt on small parts of the car and high pressure saline water sprayed into every nook and cranny of the car, I'll take the chunky surface salt every time.
There are many folks in the rust belt who claim that car washes accelerated rust by getting salt into unprotected areas.
So there's that...

Is salty water reused in car washes?

Is water at car washes recycled and full of corrosive salt that's been washed off the vehicles? Motormouth gets answers. (Rich Pedroncelli / AP)
Q: I just had my car washed at a popular local facility. I watched almost every customer hit the "free" under-carriage rinse button. Could that rinse water be recycled from the wash process? This time of year with so much road salt being washed away, I wondered if we were getting a "salt water rinse." I imagine that would simply hasten early rust and corrosion. What do you think?

A: We turned to Eric Wulf, the CEO of the International Carwash Association, who stated: None of the water that is reused and recycled in the wash process is unfiltered. Meaning, the water used for undercarriage washing is going to be filtered of much of the salinity you fear — certainly it will have much less salinity than the "raw salt" sticking to the underside of the vehicle.
