Yeah That is a option I have heard of but I do not know if the owner will go for it. It will one be costly to replace the windows as it is then 2 add the cost of that on top, he may not go for it. I will run it by him though.
We do have a water softener for our spot free but that is it. We use regular city water for all the other functions. The issue is the hard water plus chemicals getting on the windows.
I have a question. I manage a Self-Serve Carwash that has Glass between the bays. When we first opened you used to be able to see from one bay all the way into the dog wash. It was what we were known for. Made everything seem open. We loved it. Every day it was the attendant's job to rinse off...
