I just learned that many car wash places use the OLD RECYCLED water back
to use again, and that its filtered system only filters dirt.. NOT SALT..
they salt the roads where im from and that means every time I wash my car at these places im thinking its clean from salt. but really its not.! im actually getting salt back on my car again from these places..?

 

Sounds like you need to call the owner or do a taste test. I recommend the phone call.

 

i recommend the taste test. but yes its recycled water with salt in it but only the first wash with soap is recycled water the final rinse is fresh otherwise you would have salt crystals forming all over your paint and windows.

 

Sounds about right itburns. Never thought of the process before.
