^^ Your post made me curious, so I sent this question to the Customer Service email address for Delta Sonic, one of the popular car wash chains in Western NY, and also the car wash that I use several times/week on my Impreza (I have an Unlimited subscription that allows me to wash my car as often as 1x/day).
Here was my question:
I've read online that many car washes recycle the wash water, which then contains a lot of salt this time of year. Can you please comment on how fresh the water is that''s used at Delta Sonic car washes?
Here's the answer I received:
Almost all of our washes use 100% fresh water for our entire operation. We have been working on water reclaim systems at a couple of our locations, but even where we are doing that, we are only using the reclaimed water in the initial soap and power wash of the vehicles. The reclaim system does remove salt, but even so, the last 3/4 of the wash process use only clean fresh water to insure that there are no or unwanted substances in the water which could lead to anything other than a neutral surface PH insuring superior shine and protection.
I hope this has answered your questions.
So then I asked:
Thank you for your quick answer.
Can you please tell me if the undercarriage wash is in the part of the process that uses fresh water at all of your wash locations? I'm a member of your Unlimited wash program, and I typically wash my car several times/week. I'd like confirmation that the undercarriage wash isn't spraying reclaimed water, if possible.
And here's the answer:
The underspray does not use reclaimed water at any of our locations.
With that, I will continue to drive my Impreza through Delta Sonic several times/week.
